regarding tire inflation

[ron570]

I always thought tire should not exceed the amount inicated on the tire when hot. Granted I always fill when cold, but I am finding that if I put 34pi cold, hot it could go up to 36psi. The Michelin LTX M/S which I rently put on has a max on sidewall of 35psi.

Does this mean hot or cold?

My recollection is the max should be rated for cold PSI. I think most tires even say cold PSI.

they do say cold, but does that also mean it shouldn't exceed the sidewall max when hot?

if you just use 35 or less PSI cold you should be just fine

Don't forget, there is a large margin of safety. A tire that has a max of 35 psi, would still be fine at over 45 psi, or more. I don't reccomend that you over inflate it, but a diffrence of only 2 psi over the max is nothing to worry about.

the guy at the U-not-to-be-named-hauling-company saw "55" on the sidewall of my wifes' tires & would not be pursuaded to believe the tag on the door jamb about 32 psi....they held fine for the three miles of driving until I aired them down. Steering was kinda 'floppy' as if the tires were only touching down the very center of the tread. Go figure.
