I am just starting on my 124 I recently bought. One front tire has a slow leak. They both look to have some dry rot. I was going to try to put a tube in that one. But think if it is not to exspensive I should get a set of new ones. The rims don't look to have much rust. Any recommendations on tires, it has the 16x6.5-8. I will pay someone to mount them. Is it cheaper to buy these tires they sell on rims already if so are they cheap crap compared to what I have. My area I will be riding in is most always wet sometimes muddy.
