Trying to get my '50 ready for the road; three of the four tires are sort of iffy (put new tires on it about 15 years ago before the project got pushed to the back burner, and they are dry-rotted). Looking to go original 600-16, bias ply, tube type. I can find tires from Coker, but my gosh, the price seems way too high. Does anyone out there know of a supplier that is more reasonable, or is that what I can expect to pay (north of $200 a copy)?
