I’m an idiot when it comes to this stuff, which number is what, what will fit, etc and I ordered some tires from Jegs for my 63 Galaxie 427 and they are too wide. They are Mickey Thomspons, 245/60R15 and they are on the stock 15 by 5.5 Kelsey Hayes wheels. They rub on the inside at the leaf spring mount. There is another version of this tire that is a 235. Will that fit? Is there anybody out there running these wheels on a stock car with a tire package they really like? Does anyone know the backspacing on these? If I measure it looks like 4 inches. TIA.
