Gluing tires??

[JakeSpeed]

Hi Guys, I am new to the semi truck world and was curious about what is commonly done with regard to attaching tires to wheels. In racing they are glued and once worn out they are usually tossed out as the wheels are relatively plain and cheap. In scale crawling we use beadlocks a lot so wheels can be recycled. I have noticed here in the trucking world that there are some very nice wheels that are aluminum or some other type of metal, and it seems that they aren't of a beadlock variety.(I know that there are some beadlock types for semis) In this case how are the tires attached and subsequently removed? Getting superglued tires off of racing wheels can be an exercise of futility. lol Thanks for the advice.
