What does the tire have as Max on the sidewall??

 

What i usually do is just put close to what the manufacturer of the tire recommends (if it recommends 65, i'll put 55)

Check the tires after 1000 miles, if its wearing on the inside (the middle part of the tire) then its got too much tire pressure, take out around 5 PSI, if its wearing on the outsides of the tire then it needs more, put about 5 pounds in it...

Thats what i follow, but to each their own ya know...

 

Good answer Justin!!!

 

Really? Sweet I think i may have actually helped someone =D

 

yah i put in 55 ish it says 70 on the side wall juat make shure the are all the same anywere between 30 and 75 will be ok (depending on the tire and load) also make shure to check them when there cold too the presssure on the side wall is the COLD pressure if you check it when the tires are warm the air has expanded so you will think they are overinflated when they arnt.

 

I run my Dueler AT Revo's at 35psi cold - and get great tire wear. 40psi started to wear out the centers so I backed off 5

 

I usually run my tires at 35psi...doesn't matter what make or brand....or vehicle for that matter. My Ramcharger, Ram, & all 4 of my Grand Prixs run at 35psi. Although my GT has Goodyear Aquasteel runflats on it...I can run those at whatever I feel like and they still look fully inflated. 6 plys of steel will do that though [8D] I've always had a good ride at 35 psi (except for the runflats). In fact, I've had several people comment on how my 3/4 ton Ram rides like a car. I've always had great tire wear as well. I put almost 70,000 miles on a set of Goodyear Eagle GPS' on my beater Grand Prix, and the Firestone Radial ATXs on my Ramcharger have been on there for 17 years....they were take-offs that my dad purchased when he put the plow on it. They've still got around 40% tread left on them [8D]

My V10 I run at 35psi, unless I'm gonna be towing/hauling. If I'm gonna do either I bump it up to 45-55psi, depending on what I'm going to be hauling.
