Thanks for your response Bloo. I'll try what suggested and see what happens. The 650-16 tires are about the same price as the 600s but shipping is higher because they're quite a bit heavier
My 47 Nash 600 calls for 600-16 tires. Would 650-16 work ok? they're quite a bit heavier of a tire. Thought a little wider bias ply might be better. Thanks
