Ok, so who can explain this? Brand new tire at the beginning of the day @ TWS (Texas World Speedway). .
Why is this irregular wear just on the right side?

Very similar to cold tear conditions I've seen. I haven't run Michelin DOTs in a couple of years, so I can't comment on pressures.

The last case I had was more pronounced and looked like this:

It looks to be cold tear. You can do this in the first session. There are numerous senarios that can cause this.

1) Insuffecient power supply for your warmers, thus not allowing the warmers to full heat up.

2) Too high of pressure.

3) Not long enough time on the warmers before intially taking to the track.

My guess is #3. Not only does the tire need to be hot, but the wheel should actually be warm as well. Typically around 110 Deg F. Aluminum transfers heat faster than rubber. So if the wheel is not suffeciently warm, the wheel can actually suck the heat out of the tire. This will cause the tire to cold tear.

To be honest with you, your are not bad. How did the rear look?

Thanks for the info John. I'm not too worried about it as I didn't see any change in handling
Just want to know how to prevent it in the future
The wear on the rear seems normal to me, I think. . .

The rear tire looks like you need to be riding harder

Once this Michelin is done, I'll be going back to a BT-002RS front
No more mismatching. . .

I've not watched all my video closely. Perhaps we crossed at least once. I was probably blinking on the front straight and missed you roaring by.

Very possible. I noticed the trackday photog didn't get any pics of me on the front straight Probably too blurry

I found it weird that the tire did that cause I've ran Pilot Race tires in the past but this is also the first time for me to run warmers. . . ? Why does all the technical stuff with trackdays/racing have to seem so complicated

wtf? Thats one track day? I'm glad I can't ride that fast, I'd be broke buying tires for a bike.

I was running 2:04's and got 3 track days out of my tires on my previous bike (r6), with about 5k street miles and could still probably do another track day on them but it would be pushing it.

that's the power of a liter bike doing the damage.

Ha ha ha ha. Y'all have no idea. I started with a brand new rear tire Saturday morning. Even with a bit of bike trouble that cut a few sessions short mid day, I managed to completely obliterate my rear tire, a BT-003.

As I'm walking around the paddock checking out the other bikes, I notice Hooligan's. The rear tire on his 600 looks almost brand new and he had been running 48's. I believe he said it was his third track day on that tire. You little guys have all the luck...

+1 the faster you get, the more they get ate up!

Correction, 58's I think? Cause he sure as wasn't running 48's when I passed him (and everyone else and their mom ) on the front straight. Didn't see him after that I asked him afterwards what happened and where he went, he said, and I quote, "Dude, your bike is FUKKING FAST!"

Gary,
It's hard to tell from the pics.
I'd like to see the tire in person, but being as it was only the first session I'd have to say it was a combination of incorrect tire pressure and not enough heat in the rim.

I was getting the same result out of 002's out there, no warmers. Usually put a lap in and let her eat. I figured the tire did it on the right side more because you have 1/2 of the time on the right side than on the left. 10 left hemis. contacts compared to 5 right in a lap at TWS (Texas World Speedway) from what I remember. That is a helluva lot more heat in the left side. What makes it worse is when you come in for a few to tweak suspension and go back out when the tires arent really hot yet.

My BT003's wore fine. Running same sessions as you Gary and same lenth of time on warmers and same warmers and only a few secs difference in pace.


I had to plug into a different outlet because the power was going in and out on the one we were both originally plugged in to. So...were your warmers working all day?

I dont know much about pressure, but I trust John, unless you asked about pressure and it was assumed you had stones on the front as well.

Furthermore, from what Derek posted, it looks like Pilot races should NOT go straight on the warmers after a session. The label reads "DO NOT wrap hot tires" I dunno.

1. Yea, they were working all day but 1 session I think.
2. Nah, I told John I was running Mich. front and Bstone rear.
3. Yea, the Mich label Derek posted was weird. I don't get it.

I would like an explanation for the wear pattern on the right side. . .now to the pictures. . . .

Right Side

Left Side
33wac6s

TIA

-Gary
im no expert by any stretch of the imagination.
but it seems to me the right side is what caves at that track first.
i was running tyhe same tire,but ran it at 31 hot LBS.and the rear 22hot Lbs both were my last set of power races from last year.
two of the guys in our group were running sub 50's gsxrr 1K's and they're tire were gone by 3 oclock.
the front was too low and since most of the right handers there are on the brakes pretty hard(specially T2),thats what i believe tore them.
