[Fot] Tubes in racing tires.

[Jerry Barr]

Scott and I are sharing a Spitfire 1500 with Panasport rims and  
Yokohama Advan A048 tires with radial tubes. We have had 2 tube  
failures in the last 2 races. I took the tire to the on track tire  
store and the technician was asking why we are using tubes it this  
tire. I had no real answer except that is what we alway did, he told  
me there is no real reason to use a tube in a radial race tire. What  
is your opinion?
