I will put this in the wheel section also but i was wondering what would be the best tire pressure to run on the street w/ my current setup...they are 18 inch wheels and the tires are Kumho Ecsta Supra 712's 245/45zr18..i have heard that 35psi would be the best but recently someone mentioned to me that i should be running 44 psi in each tire on the street..what would yall recommend for the best fuel mileage/daily driving habits etc...

 

I will respond in the wheel and tire section since this IS the wrong forum.

 

I'll respond here just b/c,

I've ran 33-35 psi front, 30 psi rear with good wear results on Kumho's.

 

You should contact the tire manufacter. But i do know the auto company's spend quite a bit of time coming up with a proper air pressure setting for the cars suspension.

 

Well its sort of a general question because i want a general consensus to what everyone might suggest running for daily driver useage..sorry about the wrong forum..i think i will go with GM on psi unless i find any info otherwise
