Title: Tyre wear
Post by: TheBoy on 21 March 2007, 15:44:07
Something odd as happened to my car.  It passed its MOT 3 weeks ago, and I know the tyres were all OK, bit low but still some miles left in them.

So imagine my surprise when parked up on full lock at the weekend I see the osf inside shoulder was worn bald.

A quick trip to Wheels In Motion yesterday to put a pair of new Dunlops on it, and the best remain 2 tyres on the front. Alas, one of those has little left either, but they found 2 of the wheels were no longer round.

Once on the machine, the geometry was way off, but we couldn't see a single reason for it - it was as if more than one setting had adjusted. Tony had no choice but to re-setup from scratch.  Fortunately, I had my old settings, so we have a base to start from.

So currently, I need a pair of MV6 wheels, and a pair of Dunlops to go on them  :'(


But, what happened between MOT and the weekend to cause such very drastic wear on the tyre - it was camber type wear, that much even I know.

I should add I have been happy with tyre wear - thats 16k out of them (was getting 6 - 8k before Tony sorted it) - the fronts still had probably about 3mm (the shoulder wear on osf aside), rears down to near the limit for some reason ::)

But, the main thing is, the wear was flat across the tyre (except that one which obviously something went wrong), so cannot get better than that with those tyres and my driving style, so another testiment to Wheels In Motion :y

Wow thats a bit worrying... I can't imagine what they did unless it was man-handled in someway - does MOT require removal of wheels at all? I have no clue  :-/

I don't suppose the tyre had got a slow puncture and has thus been running flat?

Even so, that's a lot of wear in a couple of weeks and you would have noticed the lack of grip, I'm sure.

All the suspension parts still straight? Don't suppose the MOT inspector jacked it up on a tie rod or something?

Any signs of something having shifted underneath? Subframe mountings, collapsed bushes, etc?

It would take something to be degrees out to cause wear that rapid.

Are the out of shape wheels a clue or unrelated?

Have you hit a pot hole. Or you wife has hit one.

Or has it been kerbed at all?

You are allowed a certain amount of below 1.6mm across the width....maybe this was the case...when you had it mot'd.....or it may have been on the legal limit when you mot'd it and mot bloke couldnt be bothered to give you an advisory.

Alloys not round....sounds like you've hit a pothole or two...does happen with alloys  :(

My last cars alloys were ovalled by being righted - the Irmsher MV6 alloys are VERY fragile

No puncture, tyre pressures checked at least weekly.  Doubt MOT would remove wheels. No signs of damage underneath.  Did hit a bloody great pothole a few weeks back. Wouldn't explain why ovalled wheels were on opposite corners though.  The tyre wear was camber related more than toe related imho, and osf camber was way out (not far out of Vx spec though - about 2.5 iirc, i'll check later)

MV6 wheels very soft.  I have a buckled one in the garage....

The tyres were fine across the tread pattern. Very even wear.

Everyone drives my car, esp at work if one of the locals wants to borrow a car at lunchtime.  I trust my friends/colleagues enough for them to own up to incidents.

I would not expect them to mention clipping a pot hole if they did not get a puncture

I would expect then to mention it, in the same way I would mention it when I borrow cars (not uncommon at our place for someone to borrow mine, then I have to nip out somewhere, so I borrow someone else's)
