36 1250 15 Irok radials. everyday street drive 25 to 30 psi depending on how long of a trip.
Trail is 10 to 15 psi most of the time. Sand dunes a little less.

 

34x12.5x15 Truxus MT's between 25-27psi for daily driving. Seems the best for making an even contact patch..

 

35x12.5 r15 BFG KM2s, 26 lbs street, 8-10 lbs trail, 4-6 lbs snow wheeling.

 

so i hav to much pressure in my 31 inch general grabber at2's? 45 in all four,done it for 2 years now,havnt seen any abnormal wear in them yet. drive 100 miles round trip to work, 4 days a week. wouldnt anything super low make your gas milage suffer?

 

in colo ive known 35 to never fail no matter the size shape or color

 

I tryed this once for better gas mileage and ate the middle of my rears up pretty quick..Honestly not worth the rougher ride or the extra wear..and to be honest I hand check mileage and saw no gain..but then again I got a 5 speed and drive it like I'm Earnhardt Jr. or something...

In our 04 accord its a different story. 215/60/15 cause the 195's it came with look to small for the car lol..But ya 215/60s at 48/44psi..Gained 2mpg overall even though the tires are wider and shorter...helps especially since it sees mostly intown driving.....whis is was the 5speed though.

 

235/75/15 Bridgestone Dueler A/T 695s. I will typically run between 38 and 40 PSI when I'm pavement pounding but will soften them to about 34 when wheeling. So far I've put more than 30,000 miles on these things and they are wearing even as can be.

 

so why do you run 60? whats the max weight at that pressure?

30 psi is not really helping much at all

 

x2 Can not figure out why guys run that much air pressure just because the sidewall says it is possible to run that much. Cherokees only weigh 3000-3500 lbs before modifications, so D & E rated tires running crazy pressures is not doing anyone any good.

Probably would do better if he ran the 30 psi when DD it and air down to half that when wheeling.
