hey guys, I recently purchased a new set of wheels and tires for my monster truck. they are considerably bigger... the old tires were 140mm diameter x 80mm width. the new tires are 160mm diameter by 105mm width. should i put a smaller pinion on there to avoid overheating the motor when accelerating these big new tires? bigger pinion? 2500kv brushless w 3s lipo btw. thanks!
