Soooo many variables that contribute to that. Track surface, track temp, tire pressure, tire type and riding style (late braking vs corner speed) just name a few.

I've noticed it's usually track related when it comes to tire wear though.

 

Go to the on the throttle website then go to the Dave moss section and look for the tire wear video. All will be explained. I'll try to post a link up later

 

1.) verify your tire gauge against a known gauge. Had a gauge break and be way off before ( did a few skatey laps at 42 psi, lol)

2.) try a little higher pressure. Looks like the tire is getting too hot. Some of this is just crap you pick up in the pits, but if you look how deep the ridges are in the wavy pattern and on the sides it suggests the surface is much warmer than the carcass and you are starting to see hot tearing on the tire. I run 33 psi in the SC fronts, some of the pro guys run 35. Not saying its the pressure for you, just putting out some numbers.

3.) Is it a heavy braking track? The crushing up of the ridges between the ripples suggests the tire is struggling to hold the bike back. Either the surface is too hot and starting to sheer as mentioned earlier, or the suspension is not allowing the carcass of the tire to flex as it needs to. If pressure adjustment does not work, you'll likely need a pro suspension tuners opinion.

 

Gauge is good. I routinely check it with an identical Motion Pro gauge.

After checking my notes again compared to cooler days, I am also leaning on the tire getting too hot.

There are two heavy braking areas with one being from 185mph to a near hairpin 1st gear...and I'm not hitting it as hard as a could.

I've been playing with the front compression by slowly adding more. With only 18mm left of travel, I'm trying to find that sweet spot right before it bottoms out. I'm close though. Ohlins front and rear valved and sprung for my weight but I think you're right about going up on tire pressure.

 

that has nothing to do with wear,etc. you are picking up marbles off the track. if cars are running sessions in between then there is your answer.

 

I hadn't even thought of this as a factor when I made my post. Honestly u would have never thought of it. Tell those suckers to clean their track.

Add: after looking at the pic you cab really tell there is almost no wear on the tire itself due to all that extra rubber your picking up. The other hint that there it is not wear related is there is no uniformity to the exes rubber. It's location is also a clue. Exes rubber would typically build of on the outer edges of the tire where the tire is not being used as heavily. This is clearly rubber all over. It's like a tire condom!!!

 

What Brad said. Did you run off the line before the pits? I ran at PBIR after the cars got off the track one time and it was just like that, had to be careful for several sessions, marbles everywhere.

 

I guess the reason for this excessive wear is due to heat.

 

the thread topic is excessive tire rubber. not excessive tire wear. this has nothing to do with wear. at all.

 

So what do you suggest to avoid this tire wear?

 

dont buy a motorcycle.

 

hahahahahha classic!!!

 

Reading comprehension is so overrated nowadays.

 

I had same thing on the front Monday from running on VIR right after the AMA/MotoAmerica thing. Back looked beautiful. Front was was a mess like photo in first post. I though it was my tire melting, but obviously it just got sticky enough to pick up the loose bits. Lesson to be learned: Stay on the race line, Mr. Friedrich.

 

Lol. Kids.
