stock tires are about 3.5" tall and I put in a ballooning radius of 0.3" so that does equal 4.1". However at those speeds the ballooning may be greater than 0.3" which will increase your speed even more. IMO I'm not sure that your going to be able to gear a 3500kv motor down enough runnin 3s to run any bigger of a tire than stock. A 12-13t will prolly net you 40MPH with the ballooning you'll have at that speed. To figure in bigger tires your pinion is going to have to be crazy small unless those bigger tires don't balloon as much. I know that my slash tires don't balloon as much but geared for about 38MPH they still balloon about 0.25" on the radius. IMHO to run 3s I'd pick a little slower of a motor. Personally I think I'll be staying with 2s on my crt.5, my Medusa motor runs plenty cool, much cooler than my vxl did in my rustler, that thing got HOT!
