TurboTimmy 88 Posted July 31, 2021 I have a set of these 12mm hex road tires that bolt right on to my Plasma Edge. I was thinking of taking it out for a bashing. How much will this change in gearing affect the motor? Will it overheat? Should I change the pinion gear? Thanks for any info. Share this post Link to post Share on other sites
Snappy1 966 Posted July 31, 2021 Your motor should run cooler with the smaller diameter tyres, you will have a lower top end speed, you would be able to increase the pinion gear tooth count if you wish with no detrimental effects. Share this post Link to post Share on other sites
DeadMeat666 1675 Posted July 31, 2021 Given that you have installed touring car tires, it should be perfectly fine to go up to the stock spec of the TT02 touring, which is a 22 tooth pinion. Share this post Link to post Share on other sites
