I am hoping the rear rim I ordered will actually fit my bike. The company I ordered it from said it will but I was looking at my stock rim which is 3.25" and even that looks like a snug fit. I'm probably just stressing for no reason....

 

that is the correct size; you can run a 150 or maybe a 160 tire -- IMHO the 150 rides better

 

I'm guess you are talking about an 18x4.25 rear rim.

Ya I was talking about the 18x4.25". Thanks for the help guys!!!

 

4.25" with a 150 tire.
