Car Tire Size / Load index chart
Tire load index chart
The load index is the number right after the size: 102 in 225/65R17 102H. It says the most weight one tire may carry at its full pressure. This chart turns every index from 75 to 126 into pounds and kilograms.
- Load index 102, one tire
- 1,874 lb (850 kg)
- Load index 102, four tires
- 7,496 lb
How to use it
- Find the load index on your tire, after the size, or on the sticker inside the driver's door.
- When you replace tires, keep a load index at least as high as the one your vehicle maker lists.
- Each step up adds weight, and a higher index is never a problem for the car. A lower one can be.
- The index is the most at the tire's maximum pressure, so check your pressures before a heavy trip.
