hey, i have 215/65/15's on my stock steelies and im wondering what would be the appropiate tire pressure. the tires have max p.s.i. of 44, if that helps. thanks for the help.

 

33/31 front/rear has worked well for me. It sharpens your steering and reduces understeer just a little without too much bouncing or uneven tire wear.

The max printed on the tire is just that, the max that you can run with out problems. Did you end up getting the Potenza RE950s or was that someone else? If so, how do you like them so far?

 

must be someone else. the tires i got are bigger than the stock ones. the stock tires look tiny next to mine. should i still go with 31/33? right now, i just did 35 all around until i get some definate answers. thanks

 

I run 32 on my stockers... works great

That's really high...

Read the FAQ or just listen to everyone else. Have the front slightly more pressurized than the rear and between 30-35. nuff said, i hope

 

The sticker under my armrest says 29/29. I usually run about that around town and bump it up to 32/32 for highway trips.

 

I set my stock potenza's at 35 all around and it handles a lot better now. I am going to be playing with the pressure a little bit over the next week or so. I do have ane question though, what is the benifit of riding softer in the rear, any performance gains or just ride quality?

 

Well, for cornering performance I run just enough air to keep from rolling over into the sidewalls during high G turns. With the 16" Dunlop SP8000's, I can get away with 40psi in front. With 15" Goodyears, I had to put 47psi in to stay off of the sidewalls.

For the rear, you don't have to worry about the sidewalls because there is no weight there (weight distribution is 63/37). Adding pressure to the rear helps reduce understeer somewhat, but you have to balance that with the reduction in rear traction. With the 16" Dunlop SP8000's, I have found that 38-40 psi helps in getting the rear end around without too much loss in traction.

Of course, acceleration performance is a whole different story. More pressure = less rolling resistance + less traction. So low pressure in the front, high in the rear.
