I'm not sure you can compare a bias to a radial for exact fit because of the stance/sidewall. The new numbers are metric so 8" is 8 x 25.4 = 203 mm(tread width), so a 235 would be >1" wider tread. 205 would be right. I'm pretty sure "75's" are about the same radius as a bias, so the speedo should be OK, close enough. If you drop to a 70 or 65 maybe a bigger issue. Call Coker, for exact match to the factory size. They make radials to match and look like bias plus bias are still around...
