I had geometry done last year but just the NS rear has worn dramatically since then compared to the others. Car has just passed MOT and no advisories so what is favourite culprit do you think?

[feeutfo]

Is that one tyre different make or type..?

How has it worn? Even? Inner or outer edge...?

[pscocoa]

Sept last year I had 3 Dunlop SportMax fitted - 2 on the front and one on NS Rear.

The OS Rear was a Michelin Primacy.

The NS Rear Reading yesterday was 3 - 2.5 - 4 and the OS Rear 2 -1- 2 hence the MOT fail.

Today both fronts show 7 - 7- 7. 12 months ago NS Rear was 7-7-7 and OS Rear 2-2-3.

Actually just found another reading on NS Rear in May 2012 of 5 -5- 6 so signs were there then and I did not pick up on it.

Dunlop sport max and Michelin primacy are very different compounds, sport max being much softer offer more grip, they will wear quicker.

So to be expected, if i understand your figures correctly.

Near side rear does seem to wear out marginally quicker on mine summat to do with driveline torque through the diff/rear suspension perhaps

Roundabouts? Assuming matching pair per axle?

[05omegav6]

Possibly, there are a few round here Usually unless I get a puncture

Might be worth getting matching tyres on all wheels and then a trip to tony at WIM to look at your set up, but as chris said different tyres different compounds.
Also what is your driving style ie the boy style or Auto addict style.

[pscocoa]

presumably AutoAddict as I do not do racing starts and fast cornering.

Dealer agrees that they need to investigate as they fitted tyres and did full set up at that time.

full set up? At a dealer...? I'd be very suprised. They may have farmed it out, or guessed.

set up first

[pscocoa]

they claim to have the equipment and produce the nice red/green and then green/green diagrams

Worth a check but I'd be suprised if it's anything other than the softer tyre. Primacy are Tunnie tyres. He'd get 60k out of them. Where as TB would get 10k out of sport max.

Does the car sit right, not lopsided or low one side at the back?

[pscocoa]

Update - dealer is taking up the issue of this tyre with supplier as all other tyres wearing evenly - they have been through suspension set up etc today and can find no reason for the problem. Will see what happens.

[feeutfo]

So, the least worn are the 3 Michelin primacy, and the one that's worm most is the Dunlop sport maxx? Do I have that right...?
