I'm not really sure what you guys are talking about in terms of "roll-out", but I'm using regular 24mm medium narrow dish rims, with Tamiya B3 tires. I know the roll-out has some involvement with the final gear ratio calculation, but this is still not too clear to me.

I've been testing at the Tamiya USA track in Aliso Viejo, if any locals can shoot me some advice on this motor, that'd be appreciated.

Thanks for all the responses!
