Found some 15" Ralleys. Suppose to be 15x7's. Code on back side of rim are as follows 15x7 JJ. WP. Will they fit on a 66GS?
Todd, WP is the code for small bolt size (5 x 4.75) wheels, so that's the same on your 1966 A-body. You're going from 14 to 15 inch, but you can work that out with a lower tyre height. I'm sure that another board member will chime in about the back spacing :TU:
Todd they will fit. Down here if you can get some rims for $200.00 or less jump on it. Those up north cheap prices dont's happen much down here.I just bought a set and had to polish the hell out of them to just get driver quality. They ain't real pretty, but they are 15". Wait till you see the tire choices you get in 15", not much. Unless you got a "correct car" desire, save, save, save and go for the 17" ralleys. The tire choices are much better there. Now I got a set of useless 14" ralleys to get rid of, at least they have good tires so that may help move them.
I have some JJ's as well, paid about $65 each for some nice ones. 15x7 JJ wheels, my measurements: Front- mounting surface to edge of wheel = 3-5/8" Rear - mounting surface to edge of wheel = 4-3/8" Total width of wheel (edge-edge) = 8" offset = 3/8" 255/60-15's are a snug fit in the rear. Often, the rear isn't perfectly centered, so it might be tight one one side.... my red '66 has about a finger-tip width (about 1/2") on one side, it might rub once in a while at the outside fender/wheelwell trim. If the car is lowered, you'll have even less clearance. There is more room on the inside of the tire. An extra half-inch of offset on a wheel would be ideal, 7/8" or so. This would center the tire in the wheelwell better. That would be 4-7/8" backspace on a 7" wheel (which actually measure 8" edge-edge), or 5-3/8" backspace on a 8" wide (measures 9")wheel. I prefer the 'offset' spec since it doesn't vary with rim width. 15" tires from BFG, Firestone, and Cooper are popular choices.
