Thread: What size rear tire for 32 fendered ford?

Tweet

Here's a couple of my previous cars. The roadster has 245/70 on 15x7, the coupe 235/70 on 15x8 (if my memory is working today). The rear in the coupe was narrower than the roadster. The tires sit close to the same position relative to the fender (the roadster should have been 1/8" more rear offset), the difference is in offset. IMHO the brand of tire and the nominal wheel dimensions have less meaning (Randy's comments about weight not withstanding) than offset. For some reason folks seem to have more problems with the concept of offset than they should. It helps to have the car mocked up the way it will end up, put a straight edge on the rear drum/disc face and measure how much space you have (same for the back clearance as well), then get a tire store or online source or other tires you may have around the shop or on friends cars (many tire companies have charts) to help with cross section measurements with various rim widths and figure out what will fit.
