Hey Everyone, I have a Schwinn del mar running 26 x 2.125 tires. The question, is there a way to get 3-inch tires on this bike? My main concern is the back wheel(as the front doesn't sound that hard). I already know that 26x3s won't work at all. So I wanted to see if I could do 24x3s in the rear. I see them quite often on this site. I found online a pic of this bike having 2.5s, but they appear to be on 26s. Is it possible? I appreciate the responses thanks.
