I finally decided to put my spare in the cave last night and it was flat. New tire never on the ground. I had it mounted about 6 months ago. I filled it up and it is down 5 psi in 24 hours. Did the steel wheels require a tube? Do rivets leak? Any good way to seal them up other than a tube? Mark Nashville http://www.arrestmered.com 58 "Bugeye" 66 TR4A S2-27 WB0NOO
