Tyre wear experts

[stevierst]

Calling tyre wear experts. Has anyone got any idea why my rear Bt023 might be wearing like this? Suspension settings maybe?

I have a vague recollection of Russ (from Russ' Tyres in Portsmouth) telling me that it was caused by (I think) too low tyre pressure when he was repairing a slow leak in one of mine.

Cheers Graham, thought similar myself. I had a check once the tyre cooled down an hour after I got home and it's 38psi which is what I put it at.
I did have a play yesterday with a rider on a 1290 superduke across the Hawes to Ingleton road and we were pushing it a bit. It's a very grippy road surface that one.

Definitely suspension. I was on a website lsat week looking at wear patterns and what they are likely to indicate prior to a trackday, but for the life of me I cant remember what it was, but that particular pattern was mentioned

Had a play with the shock tonight, and the rebound was 2 clicks from max (s1000rr shock)
Could be something to do with it maybe?

It maybe, the site also had imaages of the reverse ie a lip on the forward edge of the groove (sipe?) and provided possibilities form the causes of both. Fecked if I can find it now though

That should only affect how the bike feels, eg if you hit two bumps in quick succession, does the second feel worse because the shock still hasn't rebounded fully from the first?

Yeah it did feel like the back was jacking up a bit, and it was getting a out of shape and squirrely on rough bends when pressing on.

Just watched that video, and it's interesting stuff. I watched the Dave Moss videos, but he was a bit too track tech for me.
This bloke has pointed me in the rebound direction with the feathering being on the rear of the sipes. 

Cheers, much appreciated.
