Key Rules
- Load index: total of 4 tires must exceed GVWR with margin — the tool above checks this.
- Speed rating: match or exceed stock. A lower rating overheats at sustained speed.
- XL marking: Extra Load — reinforced sidewalls for heavier vehicles, needs higher PSI.
Frequently Asked Questions
What is load index on a tire?
The number after the size (e.g. 95 in 225/60R16 95H) — it codes the maximum weight each tire can carry. 95 = 1,521 lb per tire.
What does H mean on a tire?
H is the speed rating — safe up to 130 mph sustained. Never downgrade below your car’s stock rating.
Can I use a higher load index than stock?
Yes — higher is always safe (stiffer ride possible). Lower than stock is never acceptable.
Do I need XL tires?
If your car came with XL (Extra Load), replace with XL — standard tires can’t safely carry the same weight at the same pressure.
What happens if my tires are under-rated?
Overheating, blowouts under load, and potential insurance denial after a crash. Always meet or exceed stock ratings.
