bagged out,
I am replying from a rest area near Van Horn, Texas on I-10, lol. I am in transit to Arizona.
You don't ride on the sidewalls with a car tire. Picture this: when a car takes a corner, the sidewalls flex so the thread can stay in contact with the pavement, car tires are designed that way. With a car tire on a motorcycle, the inside sidewall flexes on a turn and a big portion of the thread stays in contact with the pavement.
About the spokes, there are quite a few people on the DarkSide forum that do that, and a member of this forum just did his Heritage. do a search.
