I have just recently had a 1952 gmc 1/2 ton given to me by my father in law. trying to change out the rims and tires on it to be a little more road worthy than the skinny stock tires on it. Its a 6 lug, just wondering what the lug pattern is so i can start looking for rims, also i have read that a 205/75-16 is the equivelant tire for todays modern sizing
