Paul - good to hear that the new fronts sorted the problem. I used to get 12000 from the Pirellis on the rear of my C2, so I'm sure wear won't be too much of an issue.
Peter - I think you have answered your own question there. Bearing in mind that the slight difference between Paul's old Contis and new Pirellis was enough to upset the PSM, then the difference between 225s and 235's at the front might just do it too. Also, you would be fitting non-standard sizes, which might be an insurance issue in the event of a claim.
