All that Adrian mentioned is true Donoman.
But as for the rctech track on Tuesday nights, CS22's are by far the best tire to run there.If they don't work,its your car, not the tires fault my man!Factory guys run them and normal racers run them with excellent results.
Btw, most will disagree with you on the slicks being a disadvantage in most conditions.These are not real cars so the dynamics are not always the same.Learn to setup your car first with the tires the fast guys run at whatever track you may be at. Then if that still not sufficient, you can try other options.Stick with the cs22's though for Rctech. You cant go wrong. Oh yeah and get rid of that tc3 already and buy a Schumacher!
