Hey Snellemin, Want Some Competition?

Taller tires require more torque to get it rolling, which is time wasted in dragracing when your motor is crying to get it to roll. If I had the C50 hacker the 4" tall foamies would be ok.

you should be able to get pretty close to the same performance with the 4" tall tires by just gearing it down to the same overall rollout as what you were running with the smaller tires. That is provided the 4" tires dont weigh more, but I thing the 1/8 buggy foam tires I have seen were pretty light so that shouldnt be a problem.

Its all in the gearing.
