I just got some 28x10x16" slicks from a buddy, they're going to be going on some v6 mustang wheels. he had tubes for them but they both leak pretty bad, i was wondering if you can mount slicks without tubes? what all is involved in "screwing" them? and would that be possible to do on some aluminum wheels? I've heard before that if you clean the edges of the slicks with dawn that you can get by without tubes or screwing them, anyone heard of that?
