"Feathering".

[SLCZ3]

No chaps not one of my perversions!, trying find out why the inside edge of all four tyres are wearing excessively, on my x-type 2.5 sport 06 reg, also the garage i use is saying i need both rear wheel bearings changing, (there is some rumble from both sides), with only 45000 miles on the clock.
Thanks for any advice.

Wear on the inside edge of tyres can be caused by excess negative camber.

Suggest you find a garage with a Hunter 4 wheel alignment system and have the geometry checked. If the rear wheel bearings are not showing any physical eveidence of wear such as play or excess runout then the bearing "noise" might be caused by the unusual wear pattern on the tyres.

Hi Steve, well the "noise" started only on saturday, and looking at the tyres the camber has been out for sometime, but i shall certainly have the alignment checked.
Thanks

i
I have exactly the same car, (I've had 2 new 2.5 sports since 2003, current is an 06). Well originally jaguar decided to toe-in and then they toe-out on the front camber, as they knew about excessive wear on inner tyres but to no avail. I have learnt over the years to constantly check my front wheels on full lock as the outer tyres look perfect and you can be on the thread on the inner tyres. Had the same problem on my 03 and this not resolved on 06. On my current 06 tyre choice doesn't matter either I was on OEM P-ZERO nero went on front within 20k, was advised to move to Bridgestone Potenza and they do last longer 30K front before the dreaded inner tyre wear. Car now has 65k on 3rd set of tyres on front and 2nd set on back. I also have tracking done regularily, X type is a heavy car with wide tyres on sport 225 40 18inch these can easily go off on our potholed roads and then the tyre wear speeds up. In 7 years of production of the awd cars Jaguar never sorted out the front geometry to stop tyre wear, another problem could be bushes they can go with regularity and could be affecting the rear tyres wear

Thanks for the history, i have already replaced the fronts, since getting it in June, but i do about 1500-2000 miles a month, and it is not that obvious visually that the wear is occuring, unless as stated you take a close look on full lock.
Cheers.
