In Gary Trachy's video he says not to groove, that most people dont do it. I ordered Dunlop slicks from Motostrano, and they told me to run soft compound slicks. They said that is especially important if I dont have tire warmers yet. I noticed that Hart and alot of other pros groove the centers of their tires horizontally. I have seen excessively grooved tires get hot and chunk and or melt from grooving. I guess my real question here is should I grove soft compound Dunlops? Will I destroy them if I do? If it is ok to groove them, then how deep and how far apart should I space the grooves? Obviously I want to stick to just the center 2 or so inches so it wont affect cornering right? Please Help!!
