Well that was a painful discussion with Michelin technical - they are suggesting I shouldn't run part worn Pilot Sport with a new pair of Super Sports.
Not entirely clear if that's because of the difference in construction having a dynamic effect on rolling radius that's enough to cause problems, or just because the handling might feel a bit strange. Person I spoke to wasn't really able to justify reasons to my satisfaction.
The money tree hasn't sprouted recently and there's a pretty marked difference in tread depth to the point I wouldn't want to bin what I have. If I won the lottery this weekend it wouldn't be an issue as I could do with replacing the original spare on age grounds.....
Ho hum
