Can you put any 20" tire in a 19" mod rim?

I’ve been looking at puting in a chopper bike tire. Or if anyone has any suggestions on a tire with low rolling resistance?

Nope, it won’t work. Sorry.

Best you can do is shave a Luna smooth or something.

Ya, a 20" won’t fit, if you want a smooth tire, like Forrest said, Lunas are supposed to be the best for shaving.

I’ll pay shiping if anyone would be willing to donate an old or bald tire.

Well, I have a near bald Creepy Crawler that I’d be willing to give away in a little while except it’s kinda trash becasue it’s so balded in a place that you can see 2 patches of treads…

You’d really be better buying a Luna and shaving it…
