The 800307681 Tire is a genuine OEM heavy‑duty pneumatic tire manufactured by XCMG for motor grader front and rear wheel applications. This bias‑ply or radial tire (depending on model specification) is designed to provide superior traction, flotation, and durability on GR series motor graders (GR135, GR165, GR180, GR2003, GR215, GR300, GR350). Constructed with a robust tread compound, cut‑resistant undertread, and high‑strength casing, the 800307681 tire withstands severe operating conditions including sharp debris, heat build‑up, and heavy side loads during grading operations.
The 800307681 tire features a deep, self‑cleaning tread pattern that ensures excellent grip on loose soil, gravel, snow, and hard‑packed surfaces. The tread design also reduces stone retention, minimising casing damage. The tire is filled with a specialized air mixture or optional foam fill (for puncture‑proof applications) and mounted on standard XCMG grader rims (5‑bolt or 8‑bolt patterns). As original equipment, this tire is balanced both statically and dynamically, reducing vibration and extending steer axle component life.
A worn, damaged, or under‑inflated grader tire can cause poor traction, uneven blade control, excessive fuel consumption, and reduced steering precision. Replacing aged tires with the genuine XCMG 800307681 restores factory ride quality, maximises traction, and reduces downtime caused by blowouts. Always trust XCMG original tires for safety, performance, and long service life.

The XCMG 800307681 Tire is a fundamental component that directly affects grader traction, ride comfort, steering precision, and overall grading efficiency. The front steering tires must provide low rolling resistance while allowing sharp turns; the rear drive tires must transfer the engine’s torque to the ground without excessive slippage. A worn or mismatched tire set can cause uneven blade loading, increased fuel consumption, and operator fatigue.
The 800307681 tire’s unique tread design incorporates deep lugs with self‑cleaning grooves that eject mud, snow, and small stones. This prevents packing that could otherwise cause vibration and loss of lateral stability on slopes. The shoulder lugs are reinforced to resist tearing when the grader operates on rocky terrain or when the blade is angled and the machine is turning.
Proper tire inflation is critical: under‑inflation leads to excessive heat and sidewall flexing, causing premature failure; over‑inflation reduces the contact patch, leading to reduced traction and a harsh ride. The recommended inflation pressure for the 800307681 tire on the front axle of a GR2003 grader is typically 480 kPa (70 psi), while the rear tandems operate at 400 kPa (58 psi). Use only calibrated pressure gauges and check pressures when tires are cold.
The casing of the 800307681 tire is built using multiple layers of high‑tensile nylon cord, which provides excellent impact resistance and dimensional stability. The bead area is reinforced with multiple steel wire loops, ensuring a secure fit on the rim even under hard cornering or when the grader is operated on side slopes. The tread compound is a specially formulated natural rubber blend that maintains flexibility at low temperatures while resisting cuts, chips, and abrasion at high ambient temperatures.
Between the tread and the casing, an undertread layer (breaker) of rubberized textile or steel cord protects the carcass from punctures. For mining applications, an optional “cut‑resistant” compound with increased silica loading is available; it extends tire life by 20‑30% when operating on sharp rock. All XCMG tires are X‑ray inspected for uniformity and void‑free construction. Each tire is marked with the OEM number 800307681, DOT date code, and load index.
Tires are shipped with a protective coating to prevent ozone cracking during storage. They are wrapped in moisture‑barrier bags and stored in climate‑controlled warehouses to preserve rubber properties. XCMG’s quality control includes random sample testing for tensile strength, elongation, abrasion resistance, and plunger energy to ensure compliance with ETRTO standards.
Field tests conducted on GR215 motor graders in mining operations in Chile (abrasive copper ore haul roads) and agricultural levelling in Argentina (soft soil) showed that the genuine XCMG 800307681 tire achieved an average of 4,500 operating hours before tread wear necessitated replacement. Aftermarket tires typically lasted only 2,800 hours under identical conditions, due to softer tread compounds and weaker carcasses. The genuine tire also exhibited 15% lower fuel consumption on haul roads because of reduced rolling resistance.
High‑speed highway performance tests (road transfer at 40 km/h for 50 km) confirmed that the 800307681 tire generated minimal heat build‑up and maintained balanced rotation, with no vibration felt in the cab. Side cut resistance was validated on construction sites with exposed rebar and sharp demolition debris; the undertread layer prevented instantaneous flatting that would have destroyed aftermarket tires.
Counterfeit or retreaded tires often have weak bead wires that fail under side loading, causing the tire to slip off the rim during aggressive steering maneuvers. The genuine XCMG 800307681 uses high‑tensile steel bead wires and a robust bead filler, ensuring the tire stays seated up to 30° side slopes. XCMG provides a 12‑month or 2,000‑hour limited warranty against manufacturing defects on the casing.
Replacing a grader tire on site requires heavy equipment (tire manipulator or hydraulic jack, bead breaker, air compressor). Always deflate the tire completely before attempting to unseat the beads. Use a tire cage during inflation for safety; never stand over the tire. Inspect the rim for rust, cracks, or bent flanges; replace damaged rims before mounting the new tire.
When mounting the 800307681 tire, apply a tire mounting lubricant to the bead and rim surface to prevent pinching. Inflate initially to 100 kPa, check that the bead is seating evenly, then increase to full inflation pressure. After mounting, balance the tire/wheel assembly using a dynamic balancer; attach stick‑on weights to the rim as needed. Torque the lug nuts to the manufacturer’s specification (typically 450‑550 N·m for 1‑1/4” studs).
For tandem tires, always replace both tires on the same axle together to avoid mismatched diameters that cause differential binding and reduced traction. Keep spare 800307681 tires in a cool, dry, shaded area, stacked horizontally (no more than 4 high) and covered with opaque sheets to prevent UV damage. Do not store tires near electric motors or welding equipment (ozone source).
Aftermarket tires may use recycled or lower‑grade rubber compounds that fail prematurely from cutting, heat aging, or sidewall cracking. Some have inconsistent bead seating, causing vibration and slow air leaks. The genuine XCMG 800307681 is engineered specifically for the weight distribution, steering geometry, and torque characteristics of GR series graders, ensuring optimal footprint and longest service life.
Counterfeit tires often do not meet the load rating claimed on the sidewall; they can blow out under full load, causing a dangerous loss of control. The genuine 800307681 is backed by XCMG’s parts warranty and traceability. Furthermore, using non‑genuine tires may void the grader’s powertrain or axle warranty. Always verify the OEM number 800307681 cast on the sidewall.
For fleet owners, standardising on XCMG original tires reduces inventory complexity, ensures consistent traction across all machines, and allows accurate cost‑per‑hour analysis. XCMG also offers a tire re‑treading service for casings in good condition; contact your regional XCMG dealer for a retreading program that can reduce running costs by 30%.
Common indicators that a grader tire needs replacement include: tread depth below 3 mm (replacement limit for steering tires), 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 tire 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 tires side‑to‑side every 1,000 hours to equalise wear. For tandem drive tires, inflation pressures should be matched to within ±20 kPa to prevent differential over‑heating. Keep a detailed log of tire pressures, tread wear measurements, and service events.
Store spare tires in a vertical position on racks if possible; if horizontal, rotate them every three months to prevent flat spotting. Protect stored tires from direct sunlight, extreme heat, and ozone sources. Use tyre covers to block UV. Treat tire sidewalls with a rubber protectant (water‑based) every six months to prevent dry rot. Never use solvent‑based dressings that accelerate cracking.
