Afraid not. That's why I said "(within reason)". As long as you're in a good range (not under-inflated or over-inflated) you're good.Your logic is backwards, more PSI the faster they will wear down, the less air the more life they have.
I have my Toyo's at 40psi for daily driving, winter I ran 38 for a slight softer tread for slick roads. I find this the sweet spot for these size Toyo's we have, and to lengthen the tread wear fine. Our max is 65psi I believe, and the only need to go that high is for hard towing.
Oh, and for highway I go to 45 for economy reasons. Air down to 40 once i'm home.
However, if you're in that range, the higher pressure has longer tread life and better fuel economy. It may be a small difference, but it is better. The lower-inflated tire will generate more heat due to the increased contact friction (more wear) and will make it harder for the vehicle to turn the tires (more fuel). A good comparison is riding a bike. Try deflating the tires a little and tell me which way is easier to ride. It's not much, but it is a difference. I'm about to drop down to 45/40 for a while.
Then again, I've just recently switched to 50. I was running 45 for a while and it seemed that the corners of the far outside tread knobs were getting worn, which is why I increased it.
Nope.Hey Matt. Does Ford go crazy with a TPMS warning if you jack with the pressures like GM does?![]()
Title says it all. What are you running?
I have 33x12.5R20 Toyo M/Ts and am still adjusting the pressure trying to strike a good balance. Generally I keep the pressure high (within reason) to lengthen the life of the tires and increase economy. I don't notice any increase in ride stiffness so it doesn't bother me. I check it every few thousand miles to see how it's wearing.
Right now I'm testing out 50 psi up front and 45 psi in the rear.
245/75/16 and I go by what the tire says.

38/13.5-17 Toyos mud/terrain, 45 on asphalt, 18 front/15 Rear on gravel, 12 front/10 rear on sand and mud.
