Overall weight of the vehicle, wheel width, and weight rating of your chosen tire are the major determining factors for proper on road psi.Hello All,
I have 37” tires on my ‘19 JL.
1) What PSI is optimal for on-road driving?
2) what’s the pros/cons of riding at LOW PSI and pros/cons of riding at a higher PSI?
thanks!
It's not fair to say "even wear" for lower PSIs... you need the optimal pressure for even wear.Lower PSI = even tire wear, lower MPG, longer tire life
higher PSI = uneven tire wear, better MPG, less tire life.
correct/incorrect?
Start at 32 warm and go from there. The D rated will definitely be firm and less PSI will help with ride feelMastercraft MXT 37”
Sorry can’t provide best range but as suggested above the chalk test will provide the best chance of finding an even wear pattern.I could care less about the feel. I’ve rode it at 42 and rode it at 25. The drive is definitely different, but it doesn’t bother me.
which PSI would help the longevity of tire? A range would be helpful
Yeah, being a hybrid AT/MT with a rounded tread from bead to bead requires sticking to about 35psi. They would flex and grind away in no time, if being run low enough to pass a chalk test. I run mine at a cold 34, warm 36, and they are just starting to show signs of even wear at about 7k miles in.Depends on the tire too. People with milestar patagonias say to run them alot higher to make them wear evenly. They say chalk doesnt doesnt matter on them. Just what ive read over and over on the milestars.
