I would think that the larger motor would be just as bad on the drivetrain
Nah, most people who have gone with larger wheels and tires, my son and myself included, have done nothing but melt the spur gears. We tried many different gearing combos, but to no avail. We only managed to make them last longer but not long enough. Some may say mesh, some may clutches, but I know it was the wheels and tires, and after the change I managed to get over a gallon on one spur. Coincidence, I think not. This was the case with both trucks, 7" wheel tire combo was no good.
