1973 scamp front tire size.

Thanks, @72bluNblu . Sorry, The picture is in post #12. That is 24.2 inches high. I will look at options in the 215/60 to 225/60 range. With a 4.25 backspace.

Ah ok. Thing is that's with a 14" rim. When you go the 15" rim if you stay with the 24" tall tire the sidewall proportion looks kinda weird, it makes the wheel look smaller. If you like how that wheel looks then keeping the proportion about the same would mean going to a 25" tall tire, so the 215/60/15 would be a pretty similar look.
