Does anybody know if a set of 8.00 R15 100s tires would work under a stock 1951 F1? The truck is currently running 235/75/15's.
Thanks for the help.

 

I've never heard of a tire called 8.00 R15 100, but if it is the same or smaller than what you are currently using and will fit on your rim lip style and width, it should be ok.
Normally grown (used) tire P235/75R15 would be 9.8' wide and 29.7" diameter on a 6.5" width rim.
