Avon Storms with 8500 miles on them.
Run at 42psi ( as recommended)[attachment=19516:Reduced.jpg]
I know thats a good milage but has anyone ANY idea what is casing them to wear like this?
This is the second time out of four sets of tyres, the bikes were different.[attachment=19515:reducedTyre 2.jpg]

I had a similar problem with a set of Michelins I had. I as told the problem was the dozens of roundabouts I have to go through/around every day. Don't know if you'd be in a similar situation?

How close is your mudguard fender extender to the tyre is anything rubbing?

PM rubber56, if anyone is going to know its bound to be him

42 in the front??

I would check that. 32 to 36 is more normal in the front. 42 is more common in the rear.

My bike is 42 front and rear.

Alot of large sports tourers are 42psi at the front due to their large weight.

As regards the tyre wear, methinks you just need to change your tyres sooner than what your doing. There's no meat left on those tyres. That level of tyre wear is just dangerous.

I can't believe that people let their tyres get this bad.

Some else posted up pictures wondering why their tyres were bald. I really do wonder sometimes

It got a lot worse while I was away last week, the rear is fine and showing normal wear, the front has only just broken the min tread depth marker. figured it would last till I got back to Ireland and TBH, it didn't send me any warnings through the bars

Tommy I have often ridden tyres down to the wire simply because I didn't have the money to replace them. But I do knwo where you are coming from in that I knew exactly the condition of the tyre.
And like Kev I was also caught short on a long trip.

[STefan]

are you sure the pressure was right on that tire ? looks like not enough ... well and well worn lol

[DubCBRXX]

Roundabout wear pattern IMO.

Blackbird is similiar if you really let them go. As said, brave man letting them get that bad. Maybe try hard compound tyres perhaps.

[relaxed]

Are your wheels aligned, vertically as well as along the road? Are your front or rear wheel bearings OK? Are the swing arm bearings OK?

I set up the bike with the back wheel set vertical with a spirit level. Often need to put a slip of something under one or other side of the centre stand depending on how level the ground is. Then use the steering to set the front wheel vertical too, Then check of the wheels are aligned. Your frame or forks could be slightly twisted. Even a small off can twist forks in the triple clamps.

Vertically aligned wheels!!!!????? thats something new. Tell me how to vertically adjust a wwheel??

[Rockabilly]

really looks like its been rubbing off something. sounds obvious but don't forget the wheel goes up when you go over bumps so bear that in mind when you're checking to see what it might be.

[Larry]

I've seen this kind of wear on most of my bikes, I always just assumed it was from the camber of the roads.

Here are a few links which give all the info anyone needs regarding tyre issues. Maybe they should be posted as a sticky to avoid the same questions being asked repeatedly.

Easy. Set the back wheel vertical by adjusting the bike on the centre stand and a spirit level or plumb bob against the back tyre. Then turn the handlebars so the front is vertical too, again using the level. If everything is aligned properly the wheel alignment will be correct looking along the bike. A straight edge or tight string or laser line will show the same distance between the side of the narrower front and the rear on both sides.

If you have twisted forks, for example, you won't get the wheels aligned both vertically and horizontally. The rake of the steering head causes the front wheel to move off vertical as it deviates from straight ahead.
