What tire size will fit a 21x3.25 wheel.. Not familiar with front tire sizes .. Thanks

 

should be a 120/70/21. Pretty popular size. Not sure if anything else will fit.

Cool.. Thanks for the info... Now i should have asked this at the beginning also. I have seen a few bikes that have that front tire low profile look, instead of the half dome look.. Any ideas if that is a specific tire or the wheel that gives it that look. Thanks

 

A tire with a narrower sidewall on a 21 is usually a 21x3" wheel with a 90/21 tire stretched on to it. You could get one on a 3.5" rim but that is sketchy at best IMO.

 

Here is a 120/21 like you were asking about.
