I am browsing new wheels although I am not ready to buy yet. I want to put an 18" and would like to be able to swap directly from the stock wheel. Does it need to be 3" or 3.25" or 3.5" wide? I geuss my question is how wide are my stock rims? I think they are 3.5" am I right?

 

Wouldn't it be on your old tire on the bike now! Looksee
