hope this makes sense !
 

The back tyre ( battlewing) is quite new - less than 1000miles ??
The front trailwing no idea but about half worn I guess?

If it were "curvy road syndrome" I would expect to see a equal wear band running around the tyre. The wear on this tyre is just on each of the tread chunks for want of a better description but just the red bits on pic. The outer tread chunks and inner "blue" chunks are proud of the "red chunks" :confused1:

Maybe the previous owner ran it flat for a long time for some reason, off road perhaps?

Anyway it has to go its just not good - had a wet journey today and it was terrible.

The deathwings on the front of my XT have sort of that goofy wear also, some of the knobs are 1/8" shorter than the one right next to it. My bike acts like its on glare ice going down the gravel roads, even on pavement it is jerky like I've had a few pints too many. I have a set of IRC's GP110R, They had good ratings but probably not in the same class as Anakee's or Pirelli Scorpions( I have a front Scorpion ready to go on an XL, Dunlop 606 rear for more offroad on that bike).

Glad some else has this weird tread wear. I have scratch my head a lot trying to work out why and wondered if there was an issue with the bike! I agree it does feel a bit like being on ice in the wet on tarmac for me. I have nearly finished the tread on my one, can't wait to get new "shoes" on it - perfect timing for a trip :D Probably go with Battlewings for now, mainly because I have one here that's virtually unused the correct size for the back. That should see the summer trip out ok.

I wonder if they have different compound in some of the knobs. It just doesn't seem possible for them to actually wear that way but they do. Its like some are hard and wear resistant and mixed in some are soft and get chewed up faster.doh

Trip finished 0ver 40K on frt > 22000 rear
 

So we have just finished our latest trip in Europe. What a blast!
Changed oil today and was entering info into my maintenance database.
Noticed when I updated mileage that I have now gotten over 40,000 kms on the frt Conti Trail Attack, and over 22500 kms on the rear tire.(same brand).
You can see a recent picture of the bike we took at the Moto Guzzi factory and the tread appearance.
Visit the site at : Two Wheels move the Soul

10000KM of mostly road on my K60's rear is 55%ish and front is 70-80%

I don't think you can beat the Michelin Anakee 3's. I've talked to several that have this tire on their bikes and they really like them.

This past summer I sat in on a Michelin tire presentation at the BMW rally in Oregon and listened to some of their engineers. What they said made sense to me.

I plan on trying them when I replace the factory stock tires. The stock front does feel a bit odd and I've upped the air temp to 36 lbs which has helped. I travelled mostly paved roads so I don't need an aggressive off road type of tire.

Update so far
 

Having removed the rubbish tyre from the front in favour of a battlewing I must say it has been a great improvement. A couple of good tours and around 10K on it has given me much more faith in the front end on paved roads. Off road on the hard packed dirt and gravel its been OK for me 2 up with the wife as well. But on the slightest mud, it gets very interesting............. :oops2:

more strange wear patterns
 

Still on the wee strom - Well having finished off the Battlewings I went for Metzler Tourance next. Has been great for what its been on so no real complaints. But..........I did not expect the front to wear out before the rear. After around 20,000 miles the front is very done all round, centre and sides. The rear however has loads left on it. Both were fitted at the same time. The rear is square/flattened for sure but load of rubber left.

Any one else go through the front first? is this normal?

For the record I aint a speed freak, don't brake hard, use the rear brake, don't lock up the front or wheelie on the front wheel. Just normal touring 2 up, on paved , dirt , & gravel.
