Rims/Tires

Post by KulpFarm »

New to the forum experience! Can't quite used search function effectively.
I have a chance to get 305/50/20 rims and tires from a 1991 f150. Would this fit on a 1967 Ford F100 without clearance issues?

Thanks in advance!

My good friend Radioactive Larry sent the above link to me. Use the metric tire size converter and enter the original truck tire size and then enter the proposed tire size and you can judge the differences from there.

On an F100 I belive 235/75/15 closely matches the original size supplied on the truck. Don't know about and F250.

Might give you a good place to start with your decision. Hope it helps

It would take a lengthy post to inform/teach you about how to measure for fitment so you need to do your own homework by reading this article: http://www.hotrod.com/how-to/wheels-tir ... s-fitment/

If your tires are 235/75-15 then the 305/50-20 is 2.75" wider and 3"+ taller. Assuming similar backspacing, turn your wheels lock to lock and make sure you have 1.5" clear all the way around. That'll get you pretty close.
