I haven't.I'm running them at 36 front, 40 rear, which is not little.Maybe I should deflate them, if so, to what extent ?
They might be delaminating no modern tyre should slide like that
Are you sure your rear shock isn't the problem? I also recommend the Metzeler Z8 interact, excellent tyres. My dad has Avon Storm 2's on his SV 650 and loves them, they are a bit cheaper but still perform great and have lasted ages.
