Anyone know what size best fits on a 18 inch rim conversion on the back?  The 400 or the 450?

Does the 450 (4.5 in) rub or what?

I shot them an email and they said the 400 is the one to use. Those guys are top notch. Always responsive, great products and delivered super fast.  I highly recommend them for any aftermarket parts if your inclined to fix your bike up that way.


I really like the look of the tires. Many people dog on their performance. If I want to get agro l'll use my R1 or my dirtbikes.  Using this bike for performance riding is a bit of a joke, imho.  But its fun to run around on and easy to work on.
