Typical buggy tires are from 4.25 to 4.5 inched diameter. There are smaller and larger ones out there, but that is pretty typical

Rather than running a high rmp motor, with the cheaper stlye motors like the Feigao I find its better to run a lower RPM motor and get your speed with the gearing. I would recomend shooting for closer to the 30,000 rpkm range to help keep the motor cool. In my experience they tend to get hot quickly at more than that. A higher end motor like a Neu or Lehner could easily be pushed to 40,000 rpm without to much heat issue.Id say shoot for an 8xl on the 4s and you will have a solid setup that you can reliable gear for 40-45mph and not have alot of heat problems.


I also think that in general, shooting for a 60+ mph setup with 4s is a little aggresive on 4s for everyday running. You could probably gear it that way for a speed run or 2 but running it for exended periods like that will just overheat everything. I think on 4s a resonanable all around setup would be in the 40-45 mph range. If you want more speed than that plan to run more voltage. probably 6s if you truely want 60 mph reliably. That kind of speed isnt good for anything except bashing. You will never see those peeds on the track and anything over 40 is pretty much a waste.
