What is a tire load index?

A number on the sidewall, right after the size (the 102 in 225/65R17 102H), that stands for the most weight one tire can carry at its maximum inflation pressure.

Can I use a higher load index than my original tires?

Yes. A higher load index is always safe. Never go lower than the load index on your vehicle placard.

How much weight can four tires carry?

Multiply the per-tire capacity by four. For load index 100 (1,764 lbs), four tires carry 7,056 lbs, which should exceed your vehicle's gross weight rating.

The load index is the number after the tire size. It tells you the maximum weight each tire can carry when properly inflated.
