Hi, I,m confused about tire size and wheel backspace and offset. The sticky in the forum helps some but I guess I want to know what tire size goes with what wheel size and back spacing to put on my 69 without modifications, thanks.
I can offer what I know. I'm running off the shelf magnum 500 rims from wheel vintiques purchased from Summit Racing. They are 15x7 with a 4.25" backspace. tires are Dunlap Qualifiers 235x60 on all four with no rubbing. I also have a pair of magnum 500 rims that are 15x8 same 4.25 backspace but the outer edge of the 8" rim rubs the front upper control arm and can only be used on the rear so I use them for my street slicks.
I prefer tires the same on all 4 so can be rotated as I put on lots of miles and keep the wear even and found 235x60 with a 7" rim of 4.25 backspace to fit nicely with no mods.
