PROBLEM

In the process of building my diorama I found I needed a truck which I was able to get Now in the process of building this truck I realized that the tires (which are real rubber) required a finish that would make them look more like real tires as the ones in the kit were shiny I tried using a flat clear which turned out great colorwise until I tried to put everything together The paint I put on the tires immediately started to peel whenever I put any stress on the tire Now after all that, what shoud I have done to make the tires look like real rubber instead of something that has been treated with armorall

Help please
