Centerline wheel Pro Drag - Air leaking out of wheel - DAGNABBIT!!!!!!!!!

If you are running light weight front runners it could be the stampings on the tires leaking. We were having a pressure drop problem with race tires without tubes. The tire guy told us to rub the inside of the tire down with " Dawn dish washing liquid Regular " Mount them and get them warm. They never went flat again. We just did a set for the Demon and we had to put them on the valiant we bought because the one Valiant tire kept going flat. Spray them up with soapy water and let them sit see where the foam up. Usually at the stampings in the sidewalls you will see them foam/suds up
