Guys I read somewhere before that "blueing" of the tires was NOT GOOD!!. I uses these once and took them off my bike. I have since bought a track bike and now there are on there. The bike is always kept on stands and its in a non heated garage. Why did the edges blue? Are these shot? I was pondering getting new rubber for the first trackday, just didnt want to have to dump these if not necessary. What Gives???:bang

I have had tires look perfectly fine and then when exposed to cold the "blue" would show up. I have ridden the tires after that and the bluing would go away. There is no 100% answer on the if the tires are still good or not. Personally I would ride a cautious session on them picking up the pace throughout the session and feel them out. They may be perfectly fine but if you have any doubts change them out. Tires are always cheaper than a crash.

It's just heat discoloration, it does not mean the tire is shot.

+1 Tires will blue if you run them hard enough. My track tires are blue'd

Nice so this is a good thing. Cool, I will run the whole bike cautiously for a session or so. I am building this whole thing myself for the first time. Did a lot of work for a guy who wears a shirt and tie M-F!!

One thing I noticed about these Mich PR's Bear, is that there is a small window for tire pressure, ya gotta get it just right, as we noticed during that track day at Pocono..
