RE: proline rims
I don't know about those tires. If I were you I would go with aluminum rims. I got a set for $75 off ebay they are way better. Look at the Proline Mulcher tires. Alot of guys racing here are using those. I have a set of Traxxas Sporttraxx and also right now I'm running a set of HPI Dirt Bonz. THey are pretty decent. About $42 for the HPI tires on ebay. Aluminum rims wont strip and are WAY more balanced than the plastic rims. All about the same weight also. Hope this helps.
