I replaced my bias white walls (with tubes) & original rims, I asked questions here also and read the concerns. But after reading both sites and the description on these Roadsters, I still bought from Coker. Diamondbacks were on back order when I called them. They are bias looking radials. these are not the Coker classics they are a newer version from them called Excelsior Roadsters. I am very happy with the improved drivability albeit I only put about 500 miles on them so far. I didn’t do anything to the rims when I went tubeless. I actually got a best wheel/tire award at a show. Who da thunk, lol.
