Help Making Custom Slicks

[Metallover]

I am going to need some new tires for my crt .5 so I can easily run on asphault and pavement. I want a set of slicks. From what I see all the slicks have an inner foam. What I want to do is glue 1/4-1/2" of solid rubber to the rim.

- First off, is this a good idea? I don't know but they could be too heavy or something. I know they'll probably last forever, and that is why I want to do this.

- Secondly, Where can I get the rubber and what rubber should I use? I want a fairly soft compound for the most grip. I will be running on asphault and pavement.

Feel free to post pics if anyone has done this. I have not decided on a rim yet, but I'm thinking 1/8 buggy wheels. Any help is appreciated.
