Hello & thanks for the reply.

The bike has done less than 3000 miles and has the original "Tourance" rubber. I've tried a few different pressures, (around 29 to 35psi) in a few front/rear combinations but it still feels odd and unstable when going slowly or negotiating slow corners.

The bike is a 2014 registration so, obviously, has been laid up for an extended period somewhere, and not doing anything. There's only a side stand so wherever it was laid, up all the bikes' weight was on those tyres, all of the time. I think I'll get the wheels off of the ground to spin them to check if they're running true, or not....
