just like huck said, go to your LHS and find out what 4wd touring car that you can find parts for. then, what you want to do is get hpi racing type t tires, these run for about $20 for a set of 4 and will last you quite a while depending on what type of surface you run on..i suggest you run the 10.5 brushless over the 6.5.. if you need more help, dont be discouraged to come over and check out
