I own a 01 gt with 18 inch azuka rims i am michllen low pro tires all around. My problem is i went to rotate because my fronts are good and rear is kinda warn. But thiers a small slit in my rear right sidewall and i dident want to put it on my front. So i need to put my fronts on the back and buy 2 new front tires for the rims with the warn tires. The ones that are on thier now are 300 a tire is thier any way i can get out of the big price. What set of tires would u recomend for my front wheels with the two michellens on the rear
