Re: Cheap tires?
Cheng-shin makes a 4.00-18 tire that looks like an old Dunlop Trials Universal from the 1960s that isn't made any more. It looks great on my desert Sled Triumph that I do not intend to ride ever again. Cheng-Shins are perfect for that. They hold the air nicely and look great.
For riding get a shinko. I have shinkos here in my shop that are 20 years old, are still soft and show no sidewall cracking. Must be made of good rubber. On the road they have decent wear characteristics. Electron is right.
