REPLACING RUBBER TIRES

I've acquired 2 Gobots that don't have any tires. I was thinking about what to do about that and I came up with somewhat of a solution. Why not try tires that come with scale model cars? I measured the bots and they both are 3 inches and some change long which puts them in the 1/64 category. I've never tried this before so maybe some of you kitbashers/customizers can test it out on some of your bots or give me some better advice lol. Photos are included to show you what I'm dealing with.
Here is the link where I got the scale info from: http://www.collectablediecast.com/Size- ... _49-1.html
