O.K....O.K....it is all my fault......back in the late 1980's I was the first one with SCTA/BNI to run one of those 5 inch wheels and Goodyear tire
(Kent is right they are aircraft tires) on the sidecar. It took some... to get Tech. to pass it at that time. (right Tom) After I got it passed by Tech. a couple of car people started using them.
They don't make these tires anymore and it is near impossible to find new fresh ones. So for this year BUB I replaced the 5 inch wheel with a 17 inch wheel and new tire on the sidecar side.
Now in regards to the "Luge" not being legal at
SCTA/BNI.......Willie, they have run at Bonneville
in events using SCTA/BNI rules and records and inspected by( I believe) SCTA/BNI people..........so they must be SCTA/BNI legal...........But Hell, what do I know...........................................................................
