Are you using the correct tire size?

(This mostly pertains to after-market wheel/tire combos)

Fitment is one thing, but some of you forget about the other thing. Will the tires I'm using be strong enough for my car. Tire failures are commonly caused by over-loading and/or under-inflation. Please check to see if your tires are "strong" enough for your car. I've attached a load-index table to help everyone out.

How to use:

1. Check what the load index is on your original equipment tires. You'll be able to find this on the placard placed in between the driver's door jam.
2. Find out what the recommended air pressure is.
3. Cross-reference that with amount of weight that air pressure will hold.
4. Check the load index of the tires you are using.
5. Set air-pressure according to what the load-index table states.

Note #1. Make you check if your tires are standard-load or extra-load. Extra-load tires will say "XL" or (REINFORCED)
Note #2 If the tires you are using doesn't meet the load capacity at its maximum pressure, then your tires may fail.

I hope this helps. Be safe everyone.
