Chris - I have the same 26x9x15" Hoosier slicks on the way, and I'm mounting them on 7.5" rims. The recommended rim width is 7-8" according to Summit's catalog. I was wanting to go no larger than the 7.5" Convo Pro w/ the 5" BS so it would tuck up under the fender nicely. <img src="gr_stretch.gif" border="0">

I thought the 7.5" Convo Pro w/5" BS sticks out? And you have to roll the fender lip?
