Has anyone used wider rims with modern street tires, I have searched and really not came up with anything. I'm starting my build this summer and I'm kinda mixing old with modern for a street tracker-fighter style bike. I have a 2000 gsxr front end,2 into 1 headers and some cafe plastics, (came with bike). I know you can only go so wide on the tires,but was thinking you could get away with like some 4.25 rims, laced to the xs center hub with a street bike size tire to fit. I have a DRZ400 supermoto and it looks like it's rear tire would fit and look pretty good. I'm an old fart so I won't be riding way over the bikes capabilities, or mine. An ideas or suggestions- pro's and cons???
