Hankook tire deal and question
I found a good deal on Hankook Ventus V12 Evo tires. Delivered for $540.00, 4 tires, 225/40/18 and 255/35/18 includes $50.00 rebate. They also have a free road hazard warranty. Purchased from Gripston Tires on line. My question is what air pressure should I use? Stock run flats are 33 psi front and 39 psi rear.
