Strange tyre wear

[Rockred]

Just got the bike back from the 6000 mile service at BMW Algeciras, and the mechanic said the front tyre is wearing a lot faster than the back and he does not know why. Any ideas chaps ? The bike is 1200GS TC with conti trail attacks and I ride mostly in the mountains on tarmac some of the roads are very twisty. Thanks in advance

What pressures do you run?

I always put 22 bar front and 25 bar rear when solo, I weigh about 13 stone ish in my gear.

I ran a new set of the contis when on a 10 day trip to The Spanish Pyrenesse , the front lasted about 1800 miles and the rear did around 700 miles more after I got back.
My idea on this was hot twisty roads , spirited riding , with lots of hard braking ,carriying the front brake around the corners as you would on a track , those Spanish roads.
The wear was the same as yours I think , centre fine , shoulders worn down past the markers.

Check what your tyre pressures should be with the manufacturers website

Not with books or charts or anything

Check the website

My Old K was on Pirelli MT01 a thousand years ago and I could not get it to change direction quickly at all

After I'd checked the tyre pressures a gazillion times, stripped and cleaned the swingarm bearings changed the shock Checked the callipers weren;t binding, overhauled the front forks etc etc

I found the answer totally accidentally I was looking for tyres for my mates K1100LT and happened to accidentally click on the K100 and noticed the tyre pressures 2.5 and 2.9 bar i.e. 36F and 42R

I was running on the manual figures of 30, 32! Instant change and problem solved

22 and 25 bar, there's your problem

I've never had a bike that didn't run 36/42 and that includes all motor and mountain bikes.

EDIT: Ah ok you were talking in metric.

Where is the wear? Pound to a pinch of snuff the tyres are not wearing too much in the centre, but in the area roughly halfway from centre to edge. This is almost always due to running the tyres a little bit soft. Just up the front pressure a bit - maybe 2.3 or even 2.4 bar. Is your gauge accurate?

Thanks for all your reply's. I think it is more to do with what Stick said, as I ride a lot in them there hills and they are up hill and down dale with some tight bends.........Thanks again

Happy days ...... Keep that throttle to the max , it's the best way , who cares about tyre milage , enjoy the art of rubber degradation , it comes to a few

To me the GS is heavy on front tyres, nowhere near the 2 fronts to 1 rear I almost got on other bikes. Maybe it's the lack of feedback from the front that leads us to push it further? Or maybe that's bollox!

lack of feedback

I had conti trail attacks on my TC I used it every day for 5000 miles even at slow jersey speeds and 2 trips away per year I noticed that the front was wearing faster than the rear. I use 36 42 psi front rear. As Stick says it means your pushing into the bends and grinning. Enjoy and buy new tyres when you need em

Slow speeds and tight bends will work the front tyre shoulders. It's counter steering in action. It's a heavy old bike to haul up and down all done by steering the "wrong" way.
