I've recently talked to tire companies and they have told me that my Blazer has a very weird offset and that none of them carry a wheel and tire bigger than the standard 15 inch rim and matching tire. This is very sucky because I want to put 18 inch rims and matching tires on it. An employee told me that I'm trying to change a truck into a high performance vehicle. I Just dont believe that no one has a bigger wheel for such a decent suv. Again its a 96 S-series Blazer..4 door...4 wheel drive...Can someone help me to more knowledge. These employees were all from Oklahoma...and if anyone knows Oklahoma...its slow...so they probably didnt know what they were talkin about. Someone please help.
