Hi all. I have a problem with my front tyre. Firstly the back ground.
I am just back from my 40th birthday trip which was a big loop 7636 km (probably 1/3 dirt) run out to Uluru via, Ivanhoe, Menindee Lakes, the Oodnadatta track, the Plenty Highway, Donahue and Diamantina Development road, through Nowendoc - off the New England Tablelands etc.

I had the front tyre changed in Alice Springs because the tourance was toast after 7500km. The front forks did weep when I was on the Oodnadatta track but I put it down to 600km of standing through ruts, corrugations and big pot holes being hard on shocks and after a while the leaking did stop. The whole bike does feel a lot sloppier than when it started off.

I put on a Pirelli M21 mainly because that was all there was in Alice.

Now that the M21 tyre has done 3000km (1/2 dirt coming home) it is wearing really aggressively on the right side. Coincidently, I am sure that I corner harder to the left than the right so I am almost positive it isn�t from cornering. So therefore my questions are.
Is this because of the road camber and I haven�t had this issue before because I have always had 80/20 type road biased tyres previously?
Could it be because something hasn�t been put back together properly when the new tyre was put on?
Is it related to the leak from the fork seals?
By the way the Pirelli performed great in the dirt and sand.

Bike is going back to mr yamaha fixit man tomorrow to fix the fork seals under warranty. Hopefully this will arrest the one sided wear....

I have done probably 500km since having the seals done and the wear is getting really bad now. I have been searching high and low for an answer but I think this is it. The knobby is just making the wear really really obvious!

Thanks for everyone's help...

Sorry mate. I would love to give you an answer but I havn't got a clue. Its not something i have ever noticed on my tyres. I have mostly run duel purpose or sports tyres on my bikes. I have done about 1000miles on my army specials and not noticed it there either.

All I had to do to my army special front was to take it off and turn it around due to it wearing the back of the tread (3200 miles) it will need changing around the 4.4k mark I reckon. The wear was due to the ride back from France and down the M25 and A303 at 75-80 mph, off road the wear rate is fairly even. The rear was fine
