TEIN HAs 17x7.5 subzeros and falken azeniz tires. What tire pressure is optimal for the street. Cornering being more important then drag racing. What is everyone else running at all four corners?

well I always ran 40 PSI on my 17" tires. Every tire is different. This is a good way to decide tire preasure:

Start out at 32psi
take some hard corners and stuff, get the tires to really work, if you get out and see the tires are rolled over past the tread, you should probibly raise the PSI a bit. Dont go past the MAX psi on the tire or you may have a blow out. Also another way to decide on tire preasure is, squeeling, squeeling is bad, if its squeeling usualy (depending how good the tire is) means not enough PSI so just keep raising it till you feel you like the way it feels, its prety much preferance. I like to run mine right at the max psi so it dosent squeel. I run BFgoodrich Geforce KDW2's and at 40psi The tires own~

If they're Azenis Sports, I'd start at about 36 psi and work your way up in 1 psi increments. They like high pressures.

thanks guys. Hey Ban, They are Azenis Sport RT-215. what do you think of the new Azenis RT-615 coming? Worth the bucks?

I wouldn't be the first to buy them. I sure wouldn't pay $150 per tire for RT-215s. the new ones are supposed to be quieter, and better in the rain... good luck keeping them as sticky. :-\ Maybe it can be done, but I wouldn't hold my breath. I'm getting BFG KDs for autocross this year.

what about the Goodyear Eagle F1's?

What psi (front and back) would be good for getting the best mpg and tread wear?

on the same 17 x 7.5 wheels

As long as they're not underinflated the milage will be fine. I ran mine at 38-40 psi, because the sidewalls are a bit soft for a performance tire. You're referring to GSD3s right? or some other F1? There's a lot.
