I guess my first step is to go check my tyre pressures. But I've no idea what this is or what causes it. They look like cracks but I'm not sure they aren't little rubbings or rollings of rubber?

I noticed this whilst in the services on the way back from the AR. Had been doing a steady 85ish for ~40 miles at this point.

My Diablo Corsa III's looked like that after along spell on the motorway on the way up and back to the North / South rideout.

I think its just the rubber graining off the tyre.

I THINK its safe to say nothing much wrong with those tyres.

Had something similar (very similar I think, but hard to tell in a piccy).

I am sure soemone who knows more will be along to confirm this.

Yer bike's knackered mate, I'll give you a tenner and a half sucked Werthers Original for it. :)

Re: I don't think my tires should look like this (see photo)
 

Ooh, pre-sucked eh? Nicely broken in for you.

That could be low pressures- I had a valve stem jam slightly a while back and rode a few miles with pretty low pressure (how is it that people miss this btw? It was like riding in treacle...) and the tyre looked like it was straight off the racetrack, properly glommed up. But equally, it could just be one of those things, personally I don't expect to see it on motorway use though.

Ditto - my stock tyres looked like that when I was packing up from a recent trackday. Bloody unnerving driving around the backroads on the way home as the bits got slowly worn away back to a "normal" road condition.

I completely wrecked a half worn BT010 on a particularly rapid ride from Bedford to Glasgow when I had my 2nd ZZR1100. I wouldn't have been too surprised aside from the fact that it was absolutely tipping it down with rain for most of it. I stopped at Carlisle services and noticed my tread depth had gone from 4mm to 1mm in about 270 miles. Tyre pressure was fine, but the tyre was steaming like an overboiling kettle, which was why I looked at the tyre in the first place. The tread had ripped up worse than 2mths has. I think the lugagge I'd strapped to the back might have had an effect, as I was on my way to my ex's so we could carry on to Troon and get the ferry to Belfast for the NW200. I had to get a new tyre as soon as I got to Glasgow as the old one was totally bald by then.

Yah, but then you were on a heavier more powerful bike, and probably going a bit faster than 85mph for that matter :)

Re: I don't think my tires should look like this (see photo)
 

It weighed a bloody ton and with luggage on was almost as wide as a Mini. I did most of the A1(M) and A66 at between 110 and 130mph, which was as fast as I dare go with that much bulk on the back. Any faster and a weave set in. One stop for fuel in S.Yorks and another at Carlisle used to see me through that trip and gave the bike and tyres a much deserved rest. In the dry a weave would set in after about 100 miles, but rain would cool the shock and I could ride fast for longer periods.

I found Avon Azaro 3 AV45/46STs to be the best tyres for the ZZR11. I was getting 7.5K from a rear and 10K from the front, as opposed to 1500 from the one BT010 I tried and 5K from the usual BT020s, and the Avons gave as much cornering confidence as either Bridgestone, enough to scrape pegs regularly.

Looks like the kind of wear you get on the edges of the tyre on a trackday. I've never had on the centre though.

I thought the tyre grained on the edges as it has 2 forces acting on it, accellerating and cornering, at the same time. Obviously not.

Tyre pressures is definitely the first place to look. Suspension can also cause strange tyre wear but as you were on the motorway I doubt it would make much difference in your case.
