1966 bolt on knockoffs

[Tony C.]

I have a 1966 427 coupe and I am thinking about putting on a set of bolt on knockoffs thay are 6" wide. I would like a taller and wider tire than my standed size. but I dont want them to hit the frame or the fender. Dose any body know the best size.

Re: 1966 bolt on knockoffs

going both taller AND wider is going to run you into problems. If you go wider you need to drop the profile down a lit to try and keep the overall diameter the same.
my neighbor has 235/60-15 on his '67 and they look great. He says he gets no rubbing at all altough on CAC and CF people say that 235's will cause rubbing problems.
I want to get new tires with the bolt-on KO's also on my '65 and was hoping to go with the same size or maybe drop down to 225/60-15's if I need to.
I think the wider look of the 235's look better than the standard 205/70-15 "replacement" size most people put on. currently on my car from when I bought it last year are 215/75-15's and I get a slight amount of rubbing on the front frame at full lock but none on the fenders.

It's virtually impossible to find a "taller" tire than the standard 7.75X15's 27" diameter that will fit without rubbing due to width; wider is possible, but not by much. With the stock rim offset, 215/70 is about the practical limit, and is VERY close - may still rub at full lock bump situations like entering a driveway.
