tecciball Posted October 4, 2006 Share Posted October 4, 2006 Hey Pathians. I just got new tires for my Pathy - 255/70/16 Dunlop Rover A/T. I will be getting them installed next week. Does anyone have a suggestion on ideal air pressure for max tire life and fuel economy. Just wondering what the common experience might be.

Trainman Posted October 4, 2006 Share Posted October 4, 2006 I run my Hankooks at 45 psi but they are 10 py LT rated tires, good to 80 psi :o And at 45 it is a bit of a rough ride What are the tires rated to? Are they P or LT? If P, I would suggest keeping to the stock ratings and keep a good eye on them. Also ask the tire shop. Link to comment Share on other sites More sharing options...
vengeful Posted October 4, 2006 Share Posted October 4, 2006 The only way to know for sure is to do the chalk test. Link to comment Share on other sites More sharing options...

vengeful Posted October 4, 2006 Share Posted October 4, 2006 Draw a thick line of chalk across the tread of your tires, drive for about 3-4 tire revolutions and you can judge how you need to adjust your tire pressure by how the chalk rubs off. If it rubs off in the middle, you're over-inflated. If it rubs off on the shoulders of the tread, you're under-inflated. If it rubs off evenly, you're just right! It's like Goldilocks and the Three Bears. Link to comment Share on other sites More sharing options...
mws Posted October 4, 2006 Share Posted October 4, 2006 That's a great way to define the benchmark for optimal treadwear. From there, you may want to adjust slightly for conditions. Add a few psi more for a slight boost in fuel economy on ideal road surfaces. Lower a few psi for more traction in difficult conditions. Link to comment Share on other sites More sharing options...

max_stryker Posted October 6, 2006 Share Posted October 6, 2006 recommended tire pressure is 26psi at all 4 corners... but it really depends on what your doing with them. wheeling - different terrain = varying psi's (usually below 20psi) driving - manufacturers rec. i found is always too low so i run 30-32 for the street Link to comment Share on other sites More sharing options...
mattd123 Posted October 6, 2006 Share Posted October 6, 2006 i have firestone destinations or the truck version of them and i run them 45 all around been running that for over a year they wear fairly evenly Link to comment Share on other sites More sharing options...
max_stryker Posted October 6, 2006 Share Posted October 6, 2006 imagine a blowout at 25psi VS 45+ psi LOL Link to comment Share on other sites More sharing options...
t0ast Posted October 6, 2006 Share Posted October 6, 2006 running 35s all around. nissan recommends the lower tire pressure for a smoother ride cuz that's what soccer moms want. Link to comment Share on other sites More sharing options...
mws Posted October 6, 2006 Share Posted October 6, 2006 Yup... Just don't take it to the extremes Ford did with the explorers... Go too low and tire failure is guaranteed. Lower pressure = more sidewall flex = more heat generation. Too much heat = Carcass delamination/failure/blowout. I also forgot to mention, as you load her up, up the tire pressure but do not exceed maximum allowable by tire manufacturer. With the hatch full of camping gear and the trailer hooked up, I am up to 46 psi in the rear tires. Link to comment Share on other sites More sharing options...
