I'm rather mystified by some uneven tyre wear on my FF; Bought new Hankook set TWO years ago (275.45R20's) and they've been incredibly well wearing, having done 45,000 miles on this set. had new discs and pads all around last Summer (12) but it turns out that one of the rears became (or was originally) warped, and the pair were changed under warranty last month - very smooth again now.
However, nearside rear tyre outside edge really gone away now, but other three corners are absolutely fine. I don't throw it around and continue to long term average fuelly @ 21.4, so you'll see FF is not abused.
Tyre company (who also did the brakes) said it was probably something to do with the raise / lower air suspension, which I really don't buy as the facility is rarely used, except for 70mph cruising automatically.
I would welcome any expertise or opinion from those who know more than I - probably most of you!

check the height from the top of the wheel to the bottom of the arch, rears should be the same..

have a look underneath cos if the tyre co jacked up under something 'bendable' and bent it then that could be your cause..

or it could just be coincidence that a bush has worn... ... - .- -.

Many thanks Stan, I'll check it out and advise in due course

Tyre wear update; Booked car in for annual service and one of the rear wishbone bushes had completely worn out. Therefore the nearside rear wheel and tyre were effectively 'self tracking' - three wheel steer in a very slight fashion. All sorted, so now I can put the new tyres on! Thanks for pointing me in the right direction Stan - PM sent

Spent the best £83 I've ever spent on a car at my local KwikFit depot who now have a £70 grand wheel alignment and tracking machine. They looked at tracking, camber, four wheel alignment and a host of other things I've never heard of. I watched on a screen as they made adjustments and brought things with in the manufacturers tolerances. I could not believe the difference in the drive and the ride afterwards. I had fitted new tyres all round so I will be watching the wear patterns now.

yes the new kwikfit machine is a 'hunters' type machine, about 30k worth i'm told . it done by worshop fixed lasers reflecting off mirrors attached to all four wheels. and prints out all data before and after. my car had previously had rear and front bushes done in past, and was all over the place. took it in, and now it drives like on rails. dead straight over motorway tramlines, hands off wheel is straight too. you keep the printouts too. for reference. from previous post i assume it was 70 plus vat 83 quid. about what i remember. as all four wheels are adjusted against each other.
see it here, the guy has a garage almost as tidy as mine, NOT

That's a fair bit of kit!

Well worth doing its such a pleasure having the car track in a dead straight line.
