Jaguar X-type 2.2 Diesel Estate - Tyre Deformation - Dooda43

ATS, while looking for a slow puncture, have identified a tyre problem where the inner tread blocks are not smooth around the tyre periphery, caused by the edges of adjacent blocks not being of the same height. All 4 tyres are affected, but fronts and rears were swapped 3000 miles ago so the cause could be at either end. I am thinking of going to one of the alignment centres given on the website, or could the cause be something else?
Vehicle: Jaguar X-type 2.2 Diesel Estate, June 2006, 63000 miles, dealer serviced, never crashed.
Tyres: Michelin Primacy HP 225/45 17YR, all 4 fitted at 43000 miles

Rear subframe misaligned causing iregular tyre wear is a known fault on x type estates a good laser tracking firm should sort it.Could be something else completely different of course.

I have owned 3 x-types & all suffered the same tyre problem, but its not just x-types. very common to a lot of new cars these days as My Passats also suffered as Did a renault and my current landrover, the tyres are just starting to go the same way at 16000 miles

Thanks for your responses, guys. I'm having the alignment looked at tomorrow and will post the result (if I understand it!).

having taken it too a fast fit chain they are often keen to sell shocks or tracking. My advice would be to look at one or two other cars, even s/max and you will see the tyres wear this way.
May be IF you could find an honest & helpfull service manager in a Jag dealer they might tell you not too worry, but its finding a helpfull jaguar Dealer !! to get the answer is the difficult bit.

I've been to an "Alignment Centre", one listed on this site, and they found too much toe in on front offside and toe out on rear offside, using a fancy bit of kit. Presumably this causes the car to crab and the blocks get slightly twisted and so do not wear evenly.

As there's nothing drastic wrong I'm going to replace the rears which are down to 2mm, and swap them with the fronts. I am wary of the trade obsession with saying things are unusable - it always sounds like a sales push - so am happy to keep the distorted blocks on the back. It'll be interesting to see if they then wear straight again.
