Hey all you guys running 275/40/17 and 315/35/17 combo...what is the propper tire pressure to run in the front and rear with these sizes for my daily street driving? My wheels and tires will all be in on Friday so I'll be needing to know what the propper pressures are when I go to put them on my car after getting em mounted/balanced Friday after work. All advice is much appreciated.

It says the reccommended pressure on the sidewall of the tire...

And on the manufacturers website if you want to know ahead of time.

Oh ok thanks, I dont have the tires here yet...everything coming in on Friday.

Thanks man. Thought that tire pressures were dependent on what vehicle and whatnot aswell.

It's dependent on the load bearing capacity varying from tire to tire. You would have to check the manufacturers recommendations on the proper psi for a specific tire at whatever your vehicle and you would weigh. This information is listed on the label in the door sill, but I think that only applies for the OEM tires that came equipped on your vehicle from the factory. It'll give you an idea, but that info should be listed on the manufacturers site as well.

Thanks again man, I'll try to look em up.

im running 20psi in my back tires and like 30ish in the front. im thinking of upping the back pressure for better gas mileage cause i still dont get traction with it down low or not on street tires....

What kind of tires are you using?

Low profile street tires aren't designed to be run consistently at low air pressures.
