I said more info on the new wheel design would follow, so here it is. These wheels in photo start out .355x.170 they are designed for the Jel-Claw hot rod tire. I picked this tire because it is narrow (I don't have to cut it down) and it is very stretchy. I plan to build a range of wheels so the outside diameter can go from say .475 to say .575 maybe a little more. More wheel designs will follow later.
steve1138 to be honest I really designed these for my RTR cars I sell on Ebay. I did not think that anyone would be interested in wheels for slip on tires. I think most racers make there own. I still have to remove flashing, true, center drill and paint them. I plan to do a few set's for prize give away's at the Summer Nationals. Let me think about it.
