What PSI do you run?

[mblouir]

I run 285/75/16 E rated Revos. I used to run them,unloaded, around 42 front 35 back. I noticed that the tires were starting to cup on the fronts. This was probably due to an oversized tire and not enough pressure. I increased it back to the manufacture specs(80psi) and they have started to run good again. Driving a HD, you try to get as much softness for a ride as you can.

That's why I don't mind running mine so high--it doesn't bother me.

50psi on my BFG's.

265-75-16 load range E on my truck and I run them at 50 psi. 30-10.5-15 on wifes pathfinder runnin at 35 psi

It bothers my balls on long drives.

35 front and rear. Any lower and the fWONking TPMS light comes on on cool mornings.

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.

Hey Matt. Does Ford go crazy with a TPMS warning if you jack with the pressures like GM does?

 

[OG-TERROR]

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

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.

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.
