-- The reason that I'm interested is that I bought a spare (single) Centerline Auto Drag Wheel. I have 4 others. -- I bought it cheap, because it leaks between the 2 halves. -- I can seal it, but I thought that a tube might be an option. -- It's not a big deal, because, hopefully, I will never use it. -- As far as the Tire Shops are concerned, I would rather believe that They just don't want the possibility of a problem - Lawyers etc. They will install a tube in off-road tires, and trailer tires..
