I noticed that the front tires on my 52 GMC 350 are radials. Toyo Hyparadial 9.00R20. They are larger than the rears, and rub a bit on the leaf springs if I max out the steering. I read that radials put too much point loading on these old three piece rims. Is this a real problem? The tires are in really nice shape and they look good. I'd rather not have to replace them. I did some searching, but didn't come up with a real answer.
Thanks
