Just wanna get an idea what kinda tire pressure everyone is running, I am on my 2nd set of tires now
on 275/60-16 I was running 30psi
on 255/65-16 I am running 35psi

what is everyone else running, would I benifit dropping the pressure to 30psi on my new tires?

 

I thought you were always supposed to run them at whatever the doorjamb sticker said, regardless of size? 35psi all the way around here.

 

I Have The Toyo Proxes 275/60/16 And I Run 32 Psi In The Front And 27 In The Rear To Keep It From Riding Too Rough And For Traction Sake.....

 

I am about to drop my rears to 30, cause my stall/tune truck has no traction...and I am racing a turbo specV tonight

 

My 275/55/ 20's are marked on the door sticker at 30psi all the way around.
If you do add more, the centers will wear out before the edges will.
If you change to widder or larger than stock size tires, you need to put less than what the door sticker says.
I think with the 275/ 60/ 16's and the 255/ 65/ 16's you should run them at 32psi all the way around.

i have 305/45/22's and i ordered them with tires mounted and they put them at 47psi, i guess i should drop it down a little haha

 

same exact method here, but with a 275/60-17.

 

Tire PSI depends on the tire to be honist. If you are running a 10 ply tire (Load Range E) then your gonna be somewhere around 70 to 80 PSI loaded. If you are running a P metric your probably going to be between 30 and 35 PSI with about 44 being the Max. A Load Range C will be about 50 PSI max and 45 PSI realistic. You also need to look at tire wear and adjust PSI to that depinding on if there is cupping or not. For the cheap 265/70R17s on the trucks 35 to 38 is what I'd run. But to be honist on a 1/2 or larger truck I'd invest in some LT265/70R17s at a min if your keeping stock size. LT moves to to a Load Range C at a min which adds plys to the sidewall (stiffer) and allows for a safer loaded truck.

 

Follow the tire pressure on the tire not the door jam. Example I have a 2500 sticker says 80 psi, and if I install a P245/75/16 (max pressure 35 psi), do you really want to be the dumb a$$ who put 80 psi in a 35 psi tire? Which body part would you lose when the tire explodes? If you have a LT 245/75/16 (Load E, 80 psi max), and you put 35 psi, the heat from under inflation would destroy the tire from the inside out.

 

i have 285/50r20 and i put 40 psi in them
