Motor Grader Tires Guide: 14.00-24 vs 17.5R25 Compared
Motor grader tires guide: 13.00-24, 14.00-24 and 17.5R25 compared, G-2 vs G-3 treads, and tips for road building and mining crews.
Motor grader tires work hard in a quiet way. A grader runs long hours at steady speed, often on gravel roads and haul roads, and it needs grip to push the blade without slipping.
Common Grader Sizes
- 13.00-24: smaller graders and road maintenance
- 14.00-24: the most common size on mid-size graders
- 17.5R25 and 17.5-25: larger mining graders
Bias or Radial on a Grader?
Many road crews still use bias 14.00-24 tires because they are tough and cost less. Mining sites with long haul roads often switch to radial for cooler running and longer life.
G-2 or G-3 Tread?
G-2 is the standard traction tread and suits most work. G-3 rock tread is better on mine roads with sharp stone. L-2 is sometimes used where grip on soft ground matters more.
Tips for Longer Grader Tire Life
- Keep all six tires at the same pressure and tread depth
- Avoid sharp turns at speed with the blade loaded
- Check the tandem tires for uneven wear each week

Motor grader tires: Frequently Asked Questions
Do grader tires need to match on all six wheels?
Yes. Uneven diameters on the tandem wheels make some tires carry more load and wear faster. Fit sets of the same brand, tread and wear level, and keep pressures equal across all six positions.
How long do motor grader tires last?
On road maintenance, grader tires often last several years. On mine roads with sharp stone they wear faster. Correct pressure, gentle turns and avoiding spinning with a loaded blade all add life.
Can I fit 17.5-25 tires on a grader that came with 14.00-24?
Only if the rims and the machine maker allow it. The rim diameter is different, so you would need new rims, and the change affects speed, clearance and load. Most owners stay with the original size.
Which brands do you supply for graders?
We supply grader tires from premium global brands and from value Asian makers, in bias and radial. Many buyers mix a few premium sets for mining graders with value sets for road crews.
