2. What Is an EP Agricultural Vehicle Wheel?<\/h2>\n

The agricultural vehicle wheel<\/strong> is a purpose-engineered steel rim assembly designed specifically for the demanding operating conditions found in crop fields, rural roads, and heavy-duty farming equipment. Unlike standard passenger or commercial wheels, an agricultural wheel<\/strong> must tolerate prolonged exposure to soil compaction loads, chemical fertilizers, irrigation water, and the continuous lateral stress produced by tractor-mounted implements. This EP series has been developed using roll-formed high-strength steel technology, producing a wheel that is simultaneously lighter and more structurally rigid than conventional cast-iron agricultural wheel rims.<\/p>\n

Each wheel in this range is manufactured through a fully automated production process \u2014 from raw coil steel through pressing, forming, welding, and in-line balance inspection \u2014 ensuring dimensional consistency across every unit in a batch. The product lineup spans sizes from compact 12\u00d76 spoke-pattern wheels used on smaller agricultural trailers all the way to large-diameter 24\u00d79 multi-stud assemblies designed for heavy combine harvesters and construction-class agricultural machinery. Both SOLID face and open-spoke configurations (6-spoke and 8-ellipse ventilation patterns) are available, allowing thermal management to be tailored to the application.<\/p>\n

For buyers in Colombia, Peru, Ecuador, and across South America, the agricultural vehicle wheel for sale<\/strong> in this EP series has been verified against the road and field conditions typical of the Andean agricultural corridor. Whether you are sourcing agricultural wheel rims<\/strong> for a John Deere-compatible tractor, a CIMC trailer, or an off-road construction machine operating on a Colombian coffee or sugarcane plantation, this product line provides a certified, cost-effective, and fully traceable solution. Custom dimensions, bolt patterns, and surface treatments are available for OEM and wholesale buyers who require bespoke specifications.<\/p>\n<\/div>\n

\n

3. Five Key Advantages of Our Agricultural Vehicle Wheel<\/h2>\n
\n
\n
01<\/div>\n

Roll-Formed High-Strength Steel Construction<\/h3>\n

Using advanced rim flow forming technology with high-strength materials including SPFH590 and DP600 grades, each agricultural wheel<\/strong> achieves a weight reduction of 15\u201330% compared to conventional manufacturing methods, without sacrificing structural load rating. This directly lowers machinery fuel consumption during field operations.<\/p>\n<\/div>\n

\n
02<\/div>\n

Comprehensive Size & Bolt Pattern Range<\/h3>\n

The EP range covers wheel sizes from 12\u00d76 to 24\u00d79 with bolt quantities of 4, 5, and 10 studs, and PCD options spanning 114.3mm to 335mm. This breadth of agricultural vehicle wheel<\/strong> sizes ensures compatibility with the majority of tractor and harvester brands operating across Colombian and broader Andean agricultural markets.<\/p>\n<\/div>\n

\n
03<\/div>\n

Solid Face & Open-Spoke Ventilation Options<\/h3>\n

SOLID face wheels provide maximum structural rigidity and are preferred for high-torque applications, while 6-SPOKE and 8-ELLIPSE hand hole configurations offer enhanced brake cooling and heat dissipation \u2014 a critical advantage in the high-ambient-temperature agricultural environments common across Colombia’s Cauca Valley and coastal lowland regions.<\/p>\n<\/div>\n

\n
04<\/div>\n

100% In-Line Inspection & Dynamic Balance Control<\/h3>\n

Every agricultural vehicle wheel<\/strong> passes through automated in-line quality inspection covering runout, dynamic balance, weld penetration, and air leakage testing. National-level testing center equipment \u2014 including German RMS cornering fatigue machines and USA ITS radial fatigue testers \u2014 validates product performance before export.<\/p>\n<\/div>\n

\n
05<\/div>\n

\n

4. How an Agricultural Vehicle Wheel Works<\/h2>\n

The agricultural vehicle wheel<\/strong> functions as the primary mechanical interface between the axle spindle and the ground-contact tyre. When load is applied through the machine’s axle, force travels through the hub mounting flange \u2014 anchored to the wheel disc by the stud-and-nut bolt pattern \u2014 and distributes radially outward through the wheel disc into the rim barrel and ultimately to the tyre bead seats. The geometry of the wheel, particularly the offset (ET value), determines how the loaded tyre sits relative to the vehicle’s track width and steering geometry.<\/p>\n

In heavy agricultural applications such as tractors pulling multi-row planters or combine harvesters cutting wet-season crops, the wheel must absorb combined vertical compressive loads, lateral bending moments from tyre side-forces, and shock impulses from field debris or ridge crossings. The roll-formed rim profile used in this EP series concentrates material at the highest-stress zones \u2014 specifically the rim flange and bead seat area \u2014 while allowing controlled thinning in lower-stress regions of the barrel wall, producing the weight savings without reducing load capacity.<\/p>\n

The stud mounting system (STUD type) and solid-hub disc (HUB type) configurations each produce a different load path: STUD-mounted wheels transfer load through the wheel bolt threads into the hub flange, making torque calibration during assembly critical; HUB-centric designs rely on the center bore fitting precisely over the hub pilot diameter, sharing centering load more evenly across the entire flange face. Both configurations are available within the EP agricultural vehicle wheel range, depending on the application’s axle type.<\/p>\n<\/div>\n

\n

5. Materials Used in EP Agricultural Vehicle Wheels<\/h2>\n

The material selection for an agricultural vehicle wheel<\/strong> is driven by three competing priorities: structural strength to carry rated axle loads, corrosion resistance to survive field chemical and weather exposure, and the dimensional accuracy required for reliable tyre seating. The EP series addresses all three through a carefully specified material stack.<\/p>\n

\n
\n

Rim Barrel & Disc Steel<\/h4>\n

Primary structure uses SPFH590 high-strength hot-rolled pickled and oiled steel sheet, with ultimate tensile strength exceeding 590 MPa. Where weight reduction is prioritised \u2014 particularly on larger agricultural wheel rims<\/strong> for harvesters \u2014 DP600 dual-phase steel is specified, offering a higher strength-to-weight ratio and improved formability during roll-forming.<\/p>\n<\/div>\n

\n

Wheel Bolts & Nuts<\/h4>\n

Grade 10.9 alloy steel wheel bolts with zinc-flake or dacromet corrosion coating. For STUD-mount configurations, the stud material meets SAE J429 Grade 8 requirements. All fastener hardware included with complete wheel assemblies is matched to the specific torque requirements of the host agricultural vehicle’s axle specification.<\/p>\n<\/div>\n

\n

Surface Coating<\/h4>\n

Standard surface treatment is a two-stage process: phosphate conversion coating followed by electrostatic polyester powder coat, minimum film build 60\u201380 \u00b5m. Salt spray resistance exceeds 500 hours (ASTM B117). For buyers in humid coastal regions of Colombia or tropical plantations, enhanced epoxy primer options are available on request.<\/p>\n<\/div>\n

\n

Tyre Bead Seat Finish<\/h4>\n

The bead seat areas of each agricultural wheel<\/strong> are machined to a controlled surface roughness (Ra \u2264 3.2 \u00b5m) to ensure consistent tyre bead seating and airtight retention. This is particularly important for tubeless configurations used on modern tractors, where bead-seat integrity is the sole factor preventing bead drop-off under dynamic cornering loads.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n

6. Application Scenarios<\/h2>\n

The EP agricultural vehicle wheel<\/strong> series serves a wide range of machinery types and operating environments. Below are the primary application categories where this product is deployed.<\/p>\n

\n
\n

Row-Crop Tractors<\/h4>\n

The 15\u00d76 and 16\u00d75.5 solid-face agricultural wheel<\/strong> configurations are widely used on row-crop tractors operating in Colombia’s coffee, maize, and sugarcane plantations. The 6-bolt \u00d7 152.4mm PCD pattern is compatible with major tractor brands common in the Colombian market, including equipment serviced through Agrofertil, Agrozootecnia, and regional machinery dealers.<\/p>\n<\/div>\n

\n

Combine Harvesters<\/h4>\n

The heavy-duty 24\u00d79 series wheels with 10-bolt 335mm PCD patterns are engineered for combine harvesters and large self-propelled agricultural machinery. Negative-offset variants (e.g., JG30E08 at \u22128mm, JG30E02 at \u221222.4mm) allow the tyre to position outboard of the machine’s chassis for the wide track widths that modern combine platforms require in wet-field operations.<\/p>\n<\/div>\n

\n

Agricultural Trailer & Implement Wheels<\/h4>\n

The 12\u00d76 (6-spoke) and 12\u00d77.5 (6-spoke) models with 136mm PCD are commonly fitted to agricultural trailers, fertiliser spreaders, and towed implements. The open-spoke hand hole pattern provides visual access for checking brake condition and improves ventilation around electric brake drums on braked trailer configurations \u2014 a key advantage for compliance with Colombian road authority requirements for towed agricultural equipment.<\/p>\n<\/div>\n

\n

Construction & Earthmoving Support Equipment<\/h4>\n

Compact construction machinery operating on agricultural or plantation sites \u2014 including skid-steer loaders, compact telehandlers, and ride-on rollers \u2014 frequently uses agricultural wheel rims<\/strong> of the 15\u201316 inch diameter range. The solid-face construction and high-strength steel of the EP series make these wheels suitable for equipment exposed to the rock and root debris typical of land-clearing operations on Colombian highland farms.<\/p>\n<\/div>\n

\n

Specialty Crop Vehicles<\/h4>\n

Narrow-track specialty crop vehicles used in vineyards, flower-growing operations, and orchard rows \u2014 industries significant to Cundinamarca and Boyac\u00e1 departments in Colombia \u2014 require compact agricultural vehicle wheel<\/strong> sizes with precise offset control to avoid crop damage. The 8-ellipse ventilation pattern used on the JG53JA04 and JG78JA01 models reduces unsprung weight while maintaining sufficient disc strength for these lighter-duty applications.<\/p>\n<\/div>\n

\n

Agricultural Truck Support Vehicles<\/h4>\n

Farm support trucks, field transport vehicles, and agricultural water tankers operating on unpaved routes across the Llanos Orientales and Caribbean Coast regions of Colombia benefit from the durability of the EP series agriculture wheels<\/strong>. These applications demand consistent weld quality and corrosion resistance given the extended service intervals typical of remote Colombian farming operations.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\n

7. Regulatory Standards & Compliance for Agricultural Vehicle Wheels<\/h2>\n

When sourcing agricultural vehicle wheels for sale<\/strong> for use on public roads or in regulated farming operations, buyers must consider the applicable regulatory framework of their target country. Below is an overview of the key standards affecting agricultural wheel products in Colombia, South America, and other major markets.<\/p>\n

\n
\n

\ud83c\udde8\ud83c\uddf4 Colombia \u2014 ICONTEC & MinTransporte<\/h4>\n

In Colombia, agricultural machinery operating on public roads falls under the oversight of the Ministerio de Transporte. Resolution 3027 of 2010 and subsequent modifications govern dimensional limits for agricultural vehicles on national highways. Agricultural trailer wheels used on towed implements exceeding 750 kg must meet rim and tyre compatibility standards as defined in NTC (Norma T\u00e9cnica Colombiana) standards. Buyers in Colombia should confirm that replacement agricultural vehicle wheel<\/strong> specifications align with the registered tyre dimensions on the vehicle’s technical inspection document (RTM).<\/p>\n<\/div>\n

\n

South America \u2014 MERCOSUR & Regional<\/h4>\n

The MERCOSUR automotive and vehicle component standards (GMC Resolutions) apply to Brazil, Argentina, Uruguay, and Paraguay and influence procurement practices across the region. While Colombia is not a MERCOSUR member, many Colombian importers reference these standards when specifying agricultural wheel dimensions. The RANDON and Implementos standards widely used in Brazil often serve as a de-facto quality benchmark for agricultural wheel procurement across the continent.<\/p>\n<\/div>\n

\n

\ud83c\uddfa\ud83c\uddf8 North America \u2014 SAE & ANSI<\/h4>\n

For agricultural wheels for sale<\/strong> destined for North American markets, SAE International standards J267 (disc wheel and hub \u2014 fastener considerations) and J1995 (agricultural tractor test) govern load capacity validation and fastener specifications. ANSI\/ASABE S296 covers agricultural tractor tyre and rim matching. Buyers sourcing custom agricultural vehicle wheels<\/strong> for export to the USA or Canada should request test reports confirming compliance with these SAE standards.<\/p>\n<\/div>\n

\n

\ud83c\uddea\ud83c\uddfa European Union \u2014 ETRTO & ECE<\/h4>\n

The European Tyre and Rim Technical Organisation (ETRTO) publishes the authoritative dimensional standards for agricultural wheel rims used in EU member states. EU Regulation 167\/2013 on agricultural and forestry vehicles sets type-approval requirements that include wheel and rim specifications. Agricultural machinery exported from Colombia to European buyers must comply with these regulations, making ETRTO-compliant agricultural wheel manufacturers<\/strong> preferable for multi-market supply chains.<\/p>\n<\/div>\n<\/div>\n<\/div>\n

\nQ1. What is the best agricultural vehicle wheel size for a row-crop tractor operating in Colombia’s coffee-growing regions?
\n\uff0b<\/span><\/summary>\n
\n

For standard row-crop tractors used in Colombian coffee plantations and similar mid-altitude growing environments, the most common agricultural vehicle wheel<\/strong> sizes are 15\u00d76 and 16\u00d75.5 with a 6-bolt \u00d7 152.4mm PCD bolt pattern. These dimensions are compatible with the majority of 50\u201380 HP tractors used in that region. If you are sourcing a replacement agricultural vehicle wheel<\/strong> and are unsure of the current spec, measure the hub face width, count the wheel studs, and measure the bolt circle diameter \u2014 then contact our team with those three numbers for a direct match recommendation.<\/p>\n<\/div>\n<\/details>\n

\nQ2. What is the difference between STUD-type and HUB-type mounting on an agricultural vehicle wheel, and which should I specify?
\n\uff0b<\/span><\/summary>\n
\n

In a STUD-mount system, the wheel centre bore is larger than the hub pilot diameter, and wheel centering is achieved entirely through the tapered or spherical seat of the wheel nuts\/bolts clamping against the wheel’s stud holes. In a HUB-centric system, the wheel centre bore fits precisely over the hub pilot, so the hub pilots the wheel concentrically before the studs are torqued. For heavy-duty agricultural vehicle wheels<\/strong> on combine harvesters and large tractors, STUD-type mounting is standard in most markets. For lighter agricultural trailer wheel hub<\/strong> applications, HUB-centric mounting often provides better vibration characteristics. Your axle manufacturer’s documentation will specify which type is required.<\/p>\n<\/div>\n<\/details>\n

\nQ3. Which agricultural vehicle wheel models are compatible with John Deere or similar tractor brands commonly used in Colombia?
\n\uff0b<\/span><\/summary>\n
\n

Compatibility depends on the specific John Deere model and production year. Most 5E and 6M series tractors common in Colombia use a 6-bolt \u00d7 152.4mm PCD rear wheel mounting, which corresponds to our JG15LB01 (15\u00d76), JG17LB01 (15\u00d78), JG19E01 (16\u00d74.5), and JG20F01 (16\u00d75.5) models. For front wheels, smaller 4-bolt patterns are often used, matching our JG48JJ01 (15\u00d74.5, 4-bolt \u00d7 127mm PCD). Please provide your tractor’s model number when requesting confirmation, as some regional variants may use different specifications.<\/p>\n<\/div>\n<\/details>\n

\nQ4. How do I check the dimensions of an agricultural vehicle wheel to make sure it matches my existing tyre and hub assembly?
\n\uff0b<\/span><\/summary>\n
\n

To verify dimensions of an agricultural vehicle wheel<\/strong> for correct fitment: (1) check the rim size marking stamped on the rim barrel (e.g., “15\u00d76”); (2) measure the bolt circle diameter (PCD) using a vernier calliper across opposite studs; (3) measure the centre bore inner diameter; (4) measure the offset by finding the geometric centre of the rim cross-section and comparing it to the hub mounting face position. Compare all four values against the candidate wheel’s published specification. If you can send us a photograph of the existing wheel’s stamp markings and a measurement of the bolt circle, our team can identify the correct agricultural vehicle wheel replacement<\/strong> model for you.<\/p>\n<\/div>\n<\/details>\n

\nQ5. How do I verify that the agricultural vehicle wheel I am buying has passed proper quality testing and is safe for use on my machinery?
\n\uff0b<\/span><\/summary>\n
\n

When purchasing agricultural vehicle wheels<\/strong> from a reputable manufacturer, request the following documentation as standard: (1) material mill certificate for the steel coil used in production; (2) in-house test report covering dynamic balance, runout measurement, and air leakage test for the specific batch; (3) third-party test report from an accredited laboratory (SGS, T\u00dcV, or equivalent) covering cornering fatigue and radial fatigue per relevant ISO or SAE standards; (4) dimensional inspection report confirming PCD, centre bore, offset, and rim contour against drawing tolerance. We provide all four documents as standard for any order of agricultural wheels for sale<\/strong> from our EP product range.<\/p>\n<\/div>\n<\/details>\n<\/div>\n<\/div>\n
