Uneven tread wear?

Never seen that before on any of my bikes. Is that a "known" issue for normal street use on a 2011 DL650? I'm not going around right-handed race tracks all day

It's a Michelin Pilot Road 4. If my notes are correct and I didn't miss a set of tires, this one has 30,000km on it after 5 years.
Coming to think of it, I got lazy in checking the tire pressure every few months because the previous set never lost any air.
When I noticed a slight wobble going around corners I checked and twice the pressure was around 17psi instead of the normal 32psi I put in. Could that be the reason?

Correction: the previous set of tires lasted 16 tkm, so I must've missed a generation in my logs and this one would have about the same mileage by now.

I think that your tire pressure is too low. Check how much difference there is between the cold pressure vs the hot pressure. Have you read, https://www.stromtrooper.com/suspens...-pressure.html and https://www.stromtrooper.com/general...er-better.html or any other threads on this site wrt tire pressure?

Here's my SWAG at the problem.

I've seen this due to the 'crown' on the road. In the US it's on the left side of the tire. Since you guys drive 'left' I would expect to see more wear on the right.

Its not really the "crown", which varies greatly, but driving on the right side means left turns have more linear feet than rights. Opposite scenario for those driving on the left. The wear is usually more noticeable on the front.
However, if you have never noticed this before there could be a suspension or bearing problem.

The recommended tyre pressure for the rear is 36psi, when COLD and so you have had this tyre underinflated throughout its life. This can cause all sorts of poor wear characteristics. Even worse if you have checked them when warm.
BTW 38psi is FAR better for handling and wear than 34psi.

17 psi? Really?

You've been running that tire almost flat. At highway speeds it must have been overheating greatly from way too much flex.

Wierd tire wear is not surprising given that.

Tire leak or not checking pressure often enough?
