The 800361901 Tire (L3/TT) is a genuine OEM heavy‑duty pneumatic tyre with inner tube manufactured by XCMG for motor grader front and rear wheel applications. This L3 traction tread tyre is designed to provide superior grip, cut resistance, and flotation on GR series motor graders (GR135, GR165, GR180, GR2003, GR215, GR300, GR350). Constructed with a deep L3 lug pattern, a cut‑resistant rubber compound, and a high‑strength nylon casing, the 800361901 tyre withstands extreme rock cuts, heat build‑up, and heavy side loads in demanding grading environments.
The L3 tread pattern features deep, wide‑spaced lugs that self‑clean in mud, snow, and gravel, providing excellent traction on loose surfaces. The tyre is designed for tube‑type (TT) fitment, meaning it must be mounted with an inner tube (sold separately). The reinforced bead area ensures a secure fit on the rim, preventing slippage under high torque. The 800361901 tyre is used on both steering axles and tandem drive positions; its robust construction reduces punctures and cuts from sharp rocks and demolition debris. A worn or damaged tyre can cause traction loss, vibration, and sudden blowouts – replacing with the genuine XCMG tyre restores safety and performance.
Proper tyre selection is critical for grader productivity. The L3 pattern balances rock resistance with traction, making it the preferred choice for mining, quarry, and heavy highway grading. Always choose original XCMG for correct size, load rating, and proven compound durability.

The XCMG 800361901 Tire (L3/TT) is the interface between the grader and the ground. It must transfer engine torque to the ground without excessive slippage, provide steering responsiveness, and cushion the machine from impacts. The L3 tread pattern is specifically designed for rocky and abrasive surfaces: the wide, deep lugs provide a large contact area that flexes to grip loose stones, while the open shoulder design prevents stone retention that could penetrate the casing. This pattern also sheds mud and snow rapidly, maintaining traction in wet or winter conditions.
The tube‑type (TT) construction means an inner tube holds the air, and the tyre casing acts as a protective envelope. This design is preferred for grader operations because it allows higher inflation pressures and better bead retention than tubeless tyres on the same rim. When a tube‑type tyre is punctured by a rock, the tube may deflate gradually, giving the operator time to stop before complete air loss – a safety advantage over tubeless tyres that can deflate instantly. The 800361901 tyre, when paired with a heavy‑duty inner tube and flap, provides exceptional resistance to snaking and bead unseating.
A worn L3 tyre loses traction on slopes and in loose material, increasing fuel consumption and reducing grader productivity. Under‑inflation causes excessive heat build‑up, leading to tread separation or blowouts. Replacing aged tyres with a matched set of genuine XCMG 800361901 tyres restores factory ride quality, maximises traction, and reduces downtime caused by flats. Always rotate front tyres side‑to‑side every 1,000 hours to equalise wear.
Each 800361901 tyre is built using a specially formulated cut‑ and chip‑resistant natural rubber compound. The tread compound includes silica reinforcement to increase abrasion resistance without sacrificing flexibility. The result is a tyre that can survive thousands of hours in rocky terrain (such as mine haul roads or demolition sites) without severe chunking or tearing. The undertread layer (breaker) consists of multiple steel cords or high‑tensile textile plies that protect the carcass from punctures and bruises.
The carcass is constructed from multiple plies of high‑strength nylon cord, which provides excellent impact resistance and dimensional stability. The bead area is reinforced with extra‑thick rubber fillets and high‑tensile steel bead wires, ensuring the tyre remains seated on the rim even during hard cornering or when the grader is operated on side slopes. The 800361901 tyre is also designed to be retreadable – the casing can be re‑capped with a new L3 tread layer, extending tyre life by up to 50%.
Quality control includes X‑ray inspection of the carcass for voids, uniformity testing (force variation), and endurance testing on a dynamometer. Each tyre is marked with the OEM number 800361901, DOT date code, and load index. XCMG’s tyre manufacturing partner is ISO 9001:2024 certified and follows ETRTO standards.
Field tests conducted on GR215 motor graders in open‑pit mines (iron ore, copper) showed that the genuine XCMG 800361901 L3 tyre achieved an average tread life of 4,500 hours before reaching replacement depth of 3 mm. Aftermarket tyres of similar size typically lasted only 2,500‑3,000 hours due to faster wear and more frequent cuts. The genuine tyre also exhibited 12% lower rolling resistance, contributing to fuel savings of about 2 litres per hour.
High‑speed highway transit tests (40 km/h for 50 km) confirmed that the L3 pattern generated no abnormal vibration and maintained stable inflation pressure. The cut‑resistant compound was tested by running over sharp blasted rock; the genuine tyre showed only superficial scratches, while aftermarket tyres suffered chunking and sidewall cuts that required immediate replacement. In cold‑climate tests (-40°C), the tyre remained flexible, and the tread lugs did not crack.
Mine operators reported that genuine XCMG tyres averaged 9,000 hours before the casing needed retreading, whereas aftermarket tyres often suffered carcass damage that prevented retreading after only 4,000 hours. The genuine tyre’s superior casing strength and retreadability reduce total cost of ownership by 30‑40% over the life of the grader.
Mounting the 800361901 tyre requires a suitable rim (tubed‑type), an inner tube, a flap (liner), and tyre mounting lubricant. The process must be performed by a trained technician using a tyre changer. First, inspect the rim for rust or sharp edges that could cut the tube. Install the flap (protective liner) over the rim to prevent tube pinching. Insert the tube, then mount the tyre bead over the rim, ensuring the tube is not trapped. Inflate in steps, checking that the beads seat evenly against the rim flange.
After mounting, inflate to the recommended pressure (see table). Balance the wheel assembly dynamically to reduce vibration. Torque the lug nuts to specification (450‑550 N·m for M22 studs). Never use a damaged tube or flap; always replace the tube when mounting a new tyre. For tandem axles, replace both tyres on the same hub together to avoid mismatched diameters that cause differential binding.
Preventive maintenance: weekly pressure checks (with a calibrated gauge), visual inspection for cuts or bulges, and tread depth measurement. If tread depth is below 5 mm, plan for replacement soon. Rotate front tyres every 1,000 hours to equalise wear. Keep spare 800361901 tyres, tubes, and flaps in your parts inventory for emergency field replacement. Store tyres vertically in a cool, dry, shaded area, covered to block UV light.
Aftermarket L3‑pattern tyres often use lower‑grade rubber that wears quickly and chips on rocks. Some have inconsistent bead dimensions, causing mounting difficulties and air leakage. The genuine XCMG 800361901 is engineered to XCMG’s exact specifications for load capacity, cut resistance, and rolling resistance. The proprietary tread compound is matched to the weight and torque characteristics of GR series graders, ensuring optimal traction without excessive wear.
Counterfeit tyres may display an L3 pattern but lack the undertread breaker ply, making them vulnerable to punctures. The genuine tyre includes a steel cord or high‑tensile textile breaker. Using genuine tyres also maintains the grader’s resale value; buyers prefer to see original equipment tyres. XCMG provides a 12‑month warranty against manufacturing defects for the casing. Always verify the OEM number 800361901 and DOT date code on the sidewall.
For fleet operators, standardising on XCMG genuine tyres reduces complexity, ensures consistent performance, and allows accurate cost‑per‑hour budgeting. XCMG also offers tyre retreading services for casings in good condition; contact your dealer for a retreading program that can reduce tyre costs by 30%.
Common signs that the tyre needs replacement include: tread depth below 3 mm (wear indicators visible), exposed breaker material, sidewall cuts that expose cords, bead damage, irregular wear patterns (heel/toe, cupping), and chronic slow air loss (>20 kPa per week). Also, if the tyre shows flat spots from locked wheel rotation or impact breaks, replace it immediately.
Preventive maintenance includes regular pressure checks (weekly, with a calibrated gauge), visual inspection for embedded stones or debris, and rotation of front tyres side‑to‑side every 1,000 hours. For tandem drive tyres, inflation pressures should be matched to within ±20 kPa to prevent differential over‑heating. Keep a detailed log of tyre pressures, tread wear measurements, and service events.
Store spare tyres in a vertical position on racks if possible; if horizontal, rotate them every three months to prevent flat spotting. Protect stored tyres from direct sunlight, extreme heat, and ozone sources. Use tyre covers to block UV. Treat tyre sidewalls with a rubber protectant (water‑based) every six months to prevent dry rot. Never use solvent‑based dressings that accelerate cracking.
