So after bkizz ride Sunday I noticed I had a hole in my rear tire, looks like I hit a screw and it feel out. I don't know how deep it goes but it is partially into the groove on the treads. Other than that the tire is in good shape but I'm not comfortable riding on it. My front is about due to be changed I am starting to notice its grip isn't as good as it used to be. The bike came with pirelli's which I liked. The price is a little high and the rear didn't last long at all. This is my very first sport bike and I took it easy on the first tire so nowadays I don't think the pirelli would last me anytime. My current tire is a continental road attack great life stuck ok in the corners and would still be running it if it wasn't for the hole. It has got a little squirrelly on my a couple times on the street. I had it on the track and it did great but I can't get it hot enough to stick like that while street riding. (I'm not aggressive enough to really need it to stick that well on the street). My riding is 98% street and I doubt ill make a track day this year. My bike is an 07 cbr 1krr it calls for a 190/50/17 rear and 120/70/17 front. It has been suggested to me to me by an experienced rider on here to throw a 190/55/17 on the rear. Thoughts on this advantages/disadvantages? Will that throw my speedo off? Will the center wear out faster? I often ride to work which is pretty much 90 miles round trip straight line riding. What tires do you guys suggest I'm thinking about some pilot's but don't know which to go with. Anyone know a place that will install on the bike, for what price? Trying to save some money. Would take the tires in but I don't have the proper front stand. Thanks guys.
