i just did some searching myself

Tom - 23/24/25 is close to what i found out for 12/11/10 rollout

RCInfinity - 1/10 th scale 4WD shaft driven electric car

i also found out that i need to gear according as the tires wears down...the question is if i start with both front and rear tires the same size and the front wear out 1mm and the rear wears out 0.5mm what do i need to do with the gearing or does it need more than a gearing change??with small tires in the front is this an overdrive??what are the effects of a car being overdriven?? ....by the way i dont have any access to a tire truer so truing it back to the same size equally is out of the question

Coincidentally!!! I have a new version of the gear ratio calculator on my site. I added a "target rollout" chart, which will be helpfull in figuring out what pinion to go to on a car with foams in order to maintain the same target rollout you started with (i.e. as your tire diameter decrases).
