I've been searching for two 7.50R20 tires for a bigbolt chevy (1951) but have not found any. I have new tires all around the truck (8.25R20) but they rub the frame in the front on a stop to stop turn. The owners manual calls for the 7.50's. I know folks have run the 8.25's without a problem but if possible, I'd like to find the 7.50's.

Anyone know of a tire source? I can find 7.50's in a bias tire but not radials.

It's not a big deal but if anyone will know it is the folks using this website! Thanks.
