Hey Guys, was wondering if you can help me decide if I need to replace the OEM tires.
I have about 2200 miles on them and have about 500 miles to go before a track day. Looking at the mileage some are getting with the OEM tires, do you guys think I should replace the tires before the track day? The rear has a slight flat spot, nothing bad though and the treads have not hit the wear markers yet. The front is as usual in better shape that the rear with no flat spots on it.
I know that everybody recommends replacing both tires at the same time, so I might do the same. Right now looking at Pirelli Rosso II or III as replacement. Not sure If I will change the profile though - anybody see any clearance issue with the 55 rear profile and the tire hugger plastic?
Yes, replace them if you can afford to. You do not want to go to the track with poor tires, brakes, etc.
There are categories of tires but for the sake of discussion these are the main ones. Track/race only, Track/Road, Sport, and Sport Touring. These are not hard and fast categories, some blend the lines between categories quite well.
Track/race only are basically slicks and a few other tires that you probably have never heard of.
Track/Road would be the best for track days and street riding. But they wear out fast, but stick well. If you run a fast pace, they get greasy after 6-8 laps. I use these on my GSXS. I use the Bridgestone RS10, 190/55. The Pirelli Super Corsa V2, Metzler Race Tec, Michelin Power RS, Dunlop Q3 are all example of a road/track class of tire.
A sport tire will be more designed for the road, but you can get away with it at a track day if you are not that fast of a rider. Examples of these are Pirelli Rosso II-III, Michelin Pilot Power III, Bridgestone 21 Evo, Metzler Sport Tec, etc.
A sport Touring should not be used on the track. People do, but it is not designed for that environment. Examples include Pirelli Angel GT, Dunlop Sport Max, Michelin Pilot Road, and a whole bunch of others. I have never used a sport touring tire because I value grip over all else in a tire. Which is why i have the RS10's on the GSXS (the rs10 is arguable the stickiest tire in the track/road class of tires).
