Did anybody make a 17" wire wheel that looks like a 21" for a Model T?
17" was the popular size for 1933, 34. i would guess there are some that would have the same bolt pattern, they will be wider too, like 5.50x17
19's look closer than 17's for a t although the hub opening is larger, larger yet on a 17". On either the bolt pattern will be wrong for a T. KGB
Keith is right on the hub size, the trend for larger hub caps had started about then too. i've had artillery wheels on t frames made into wagons, sorry do not know what brand of car they would have come on though
