liner tubes?

what tube is everyone using now for inner liners? i have heard of a standard tube and you put a valve near the edge of the wheel for the outer pressure. does anyone have the tube part number?

 

Goodyear tube. 8.00/8.20-15 you can call competition tire east and talk to Brent Auge, he will know what your talking about. Cost is approx.$50 each.Then go to Napa and get a valve stem that has 1/8 inch pipe thread on the end to thread into the wheel after you drill and tap it.

 

thanks mike, how are you making out?..... i'll be at e-town, if you come down , stop by....
