750 Street Darkside with sidecar
So the RGU sidecar rig has gone dark. Now time to figure out the Street 750 sidecar rig . Factory tire is a bit odd shaped a 140/75R15.
looking at 3 options now that should work. Looks like plenty of room . With a Street tugging a sidecar IMO a tire that lower ration would be better than one that raises it. However 1/2 MPH at 65 would make no real difference.
165/65r15 would be an inch wider than stock and it you be very close on gearing 65.49 vs 65 MPH
165/60R15 would be almost prefect 63.68 vs 65 Mph.
155/60R/15 would work 62.36 vs 65 mph
Infantry leads the way
