My son and I were sanding our wheels this past weekend. I ended up using some micro mesh that I have for pen making to sand the tread of the wheel surface. But I wonder if I should back off on this - thinking that it might cause some sliding rather than rolling. How far do you guys go?

My son and I were sanding our wheels this past weekend. I ended up using some micro mesh that I have for pen making to sand the tread of the wheel surface. But I wonder if I should back off on this - thinking that it might cause some sliding rather than rolling. How far do you guys go? Let me use another type of racing to make my point. In auto racing, you slide the wheels to scrub off speed. To go faster you must be smoother/cleaner through the turns. So IMHO, any sliding of a wheel is bad and increases friction, which should then translate into slowing the car. I leave my wheels a little rough on the tread to promote the wheels rolling rather than sliding, but I polish the inside edge that touches the guide to a mirror finish and lube it. Good Luck! |

I agree. If the wheels are polished slick they will amplify any wiggle in the car. I would want to ruff them some to help them grip the surface better to help the car roll strait.

My thoughts on this. These are gravity power cars and not 700-1500 hp cars. I would get them as smooth as you can, but do not use any lube on them. Using lube like graphite on the outer tread surface can slow you. You can not get your wheels clean enough, polishing them will help to keep them clean after several runs. Good luck with your race.
