I will put this in the General 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...

Whatever the manufacturer suggests. If the tire says 25 - 35 psi then keep the psi in that range for normal driving. Too much or little can cause premature wear and even failure.

i run the min that the tire says in the rear and almost the max in the front. usually i keep about 20-22 in the rears if im looking for a race.

I contacted BFG about my 02 SS & they said 30 PSI front & rear.

So many different answers....Well im not looking for a race cause i know the less pressure gives you a bigger tread pattern for grip but thats not my problem..im not a stoplight warrior..well i am, the car aint lol...im just looking for what will give me the best fuel mileage..all the tires say on the outside is not to put anymore than 44 psi max pressure in them..so i will prob run 35 in them just because thats what the factory recommends

Ther eis no "perfect" air pressure . . . anywhere between 30 to 35 psi for street use is about normal.

The best test is your driving impression, start at a PSI, say 35. if the car pulls intot he ruts etc, then adjust the pressure, down to get the right feel.

I keep mine at 32 psi cold.
