ok i have a 91 chevy silverado,2500. so my wheelbearings and dust cap stick out kinda far. my problem is that i decided to change my wheels and mounted the 08 oem chevy 20" rims on it. looks nice yes but so that the wheels would fit and i could place the center cap on i put in a 1/4"spacer.

ok they fit and i could fit the center cap.but when i make tight turns the tires rub.they rub on the frame.the tires are the regular goodyear ls2 tires 275/55/20. how do i fix this problem?should i get thinner tires and if so what size? or should i get the wheel adapters?or is nothing going to work for me?

someone help.ill need new tires soon so someone try and get with me asap.
