Tire flipping?

Just wondering what your take is on flipping my rear SC2. 5 trackdays at T hill and the left side of the tire is about at the wear marks while the right is fine. Should I just buy another tire or flip the tire?

Thanks

I flip all the time. I try to do it before I hit the wear marks so when I eventually turn right there is some carcass holding in heat though.

It's already too late. If you are gonna flip it, do it sooner to even out the wear.

Some DOT race tires have plenty of grip until they look like slicks, esp if you use them reasonably fast. Others don’t, esp if they heat cycle out. If u only have 2 days in it I’d def flip it. If u have 4-5 days on it, I’d toss it. But that’s just me.

I have no issues flipping my Dunlop slicks, but could you elaborate on the ďheat cycle outĒ comment Robert?? What am I watching for on that??

Thx

Heat cycle out == grip lost due to heat cycles. Tires can harden when they are heated and cooled. I put my warmers back on unplugged at the end of the day to prevent this.

But to be honest, it doesnít happen much anymore to any tire. Modern tires are really good at providing grip throughout their whole life no matter the conditions. The only way I can see this happening is if someone uses a tire for many many days, like 5+. This suggest they arenít going fast enough to wear it in 2 days, allowing them to heat cycle it a lot. Maybe itís possible w an Pirelli SC2 or Dunlop Med+ cuz u can use them that long. Racers never experience this cuz they donít use those compounds.

The thing to lookout for is the same w any tires... grip is decreased. U canít tell unless u use the tire too

A lot of big bike racers use the SC2. The SC1 just wears out too fast. You can heat cycle one out, as you said, it takes a while. I've got one on the 750 with lots of meat left and it's like jelly. Maybe 1200 track miles on it. On the 1000 the same compound lasts three trackdays if I am luck and it's gone, no meat left.
