Im trying to help someone out with some tires. They were in a bad situation and need 4 tires on a 92 Buick Roadmaster. I have 4 good used 235/75R15s here at my shop, but the car calls for 225/70R15. I know on a Caprice or any other fullsize GM 235/75R15s fit just fine but the Roadmaster appears to sit a little lower and it has rear fenderwells that overhang the rear tires. I know that the width is only 10mm different shoulder to shoulder and about 1.5" difference in overall height, but since I dont have a tire machine i gotta take my tires somewhere else to change them out. I dont wanna pay to have them mounted and be wrong. Anybody know if i can get the 235/75s under the Roadmaster, without any rubbing anywhere?
