[Closed] Car Rear Tyres Wearing On Outside Edge.

Don't live in Milton Keynes do you? That place murders the outside edge of tyres... 😀

(sorry, no other than alignment, I've nothing constructive to add)

Odd that it's rear tyres wearing un-evenly, even front's shouldn't do that in 10k.

Could be alignment...my Puggy Partner had this and turned out all 4 wheels needed tweaked slightly. So far the new tyres all appear to be showing even wear, so it seems to be working.

Might also be worth checking the suspension 'stuff'...I think (but not certain) that there may be something about an issue with the rear suspension set up that can cause this as well...

Makes me think something's had a whack.

OP, both sides wearing the same way and equally?

Edit: and its wheelchair adapted is it?

Maybe it needs adjusting to be more stance?

Yep.
It had only done around 2K when we got it.
Was a demonstrator from a main dealer.

It sometimes has two ebikes in the back of it.😆

It's made to carry some load so it could just be that the suspension geometry is designed to wear the tyres evenly when partially loaded up. Complete guess though. There won't be anything to 'align' on the rear suspension, there isn't usually anything that can be adjusted on bog standard road cars on the rear. As someone pointed out, it could have had a knock that's slightly bent something.

I'll be surprised if there isn't some sort of camber adjustment on the rear, ever car I've owned in the last 20 years has been adjustable.

Well as above, accidents can cause mis-alignment or degraded bushings or broken springs. Although broken springs on my car wore the inside edge not outside.

Are they the right size tyres and wheels? Some wheel/tyre combos wear badly on some cars anyway in normal use. Go and look from behind the car - are the wheels obviously misaligned? Perhaps get a digital level, find some level ground and check what the camber on the wheels is?

Looking at the pictures of the rear suspension it looks like the way it's bolted on it could actually be misaligned, and at that age it would have to be a manufacturing problem. So if it's out of spec, call the dealer as I presume it's in warranty..

Not on mine. AFAIK you can only adjust camber on cars with multi-link suspension. Torsion beams generally don't have that and I've had a few of those.

Yup, have had to change a stub axle on a torsion beam car that had an alignment issue in the past

Toe in on the rears
There will be some adjustment somewhere.
Bet if used the string box set up you would see 2 or 3 degrees of toe in.
Not all 4 wheel alignment centres are equal. Up against the clock outside in the cold, away from view mostly staffed by a lad with a smart phone attached to his hand.
The volvo uses an eccentric washer on a trailing arm to set up the rears.
Never had camber set up, thats for full independent suspension with upper and lower links on the rear.

Not the same car but we have this on a 2010 Peugeot 5008. Nearside rear always wears on the outer edge. With my uneducated look I can't see anything that could be adjusted and a quick google seems to agree. I should really get a professional opinion on it but never seem to get round to it or remember when the car is in the garage.

This is true. I used to to Kwik Fit and got good results, however it never lasted particularly long. I thought it was something wrong with the car. However I took in the Merc after I got it, and they really ballsed it up three times, once so bad that I drove out of the car park and brought it straight back as it was obviously cack. I'd watched the guy get the numbers right, then when they put it back on they were wildly out! I watched them put the thingies on the wheels differently each time too.

Then I took it to a Merc specialist, he charged for an hour's work on it and went into a bit more detail. He said that the camber adjust bolts were seized in their bushings. So when Kwik Fit had leaned on them to adjust the camber on the ramp they'd put tension in the rubber bushings, which had just turned the bolts back again. That doesn't account for all the weirdness I experienced that day but it highlights the difference between a while-u-wait type place and an actual mechanic.

Got the older shape Berlingo and never had that, usually get around 20-25k from a set of tyres. As everyone has said it'll be something to do with alignment.

I've found that the tyres wear pretty evenly front and back. Something to do with weight distribution compared to when the are setup as a van.

Blimey. They've not even looked at it yet and it's already their fault. 😀

Lets see what they say tomorrow after its been checked.
Unfortunately its just out of warranty and the dealer is in Bristol, which is a fair old drag from where I now live.

Previous car also wore rear tyres out on the edges but it was a company car so it didn't bother me in the slightest.

Only if your handy with a grinder and a welder on the rifters rear axle.

Beam axle on trailing arm with coil strut? Maybe not then if the psa haven't moved on frpm 90s build tech.

"I’ll be surprised if there isn’t some sort of camber adjustment on the rear, ever car I’ve owned in the last 20 years has been adjustable."

I've never had a french car that's had rear camber adjustment, and I must have had a dozen or so...

Something to do with how you drive? 🙂

Indeed. 90s tech that works. Not everything needs to be ruined by innovation

How's your driving style OP? I hate to ask, but had an old staff member who couldn't correlate 'making progress' with extreme tyre wear...

I drive a 2018 Berlingo and have the same issue with one rear tyre wearing excessively in the outside.
I do a lot of miles and change them regularly, maybe twice a year but this particular one will be three times.
Guy at the local tyre place says it's really common on this type of van. I don't pay for them so I'm not too bothered. It's been in for alignment etc but makes no difference. Driven from new so no bangs or anything.

10,000 for a set of rears, with little load ? Something isn't right.

Didn't 205s do this when the rear beam needed rebuilding? Aka bushes and bearings are shot?

But yeah, my immediate thought was also 'excess toe in'.

That was inside edges.

Sounds to me like alot of driving around unladen in a van....

What tyres are they?

I do have a Rifter (7 seater) will check tomorrow.

How’s your driving style OP?

Very sedate now I'm not rushing round all over the country trying to get to customers.🙂
Let's see what the test results are later this morning.

What tyres are they?

Michelin 215x60x17 that were standard on it.

I have to say, having thought about it, I am convinced our old Touran wore through tyres much quicker than any other car we have had. Often on edges - and we got 4 wheel alignment a few times in the 5 years we had our, having driven many miles on potholed Highland roads...
.

I wonder if it is a load thing - suspension set-up for a wide range of loading scenarios & running around unloaded means the suspension geometry is compromised.
Try sticking 2 bags of hardcore in the boot, although not sure that will do your economy any good!

I had all 4 tyres replaced on my car last weekend. The rears were the originals & the fronts were not.
Both rears were also worn on the outside edge - down past the wear indicators - rest of the tyre was above the wear indicator at perhaps 2mm. That was on 38k miles. I'd be a bit miffed if the rears were dead in 10k miles!

Was also one of my thoughts.
Just had a closer look at the fronts and though no where near as bad they are also worn on the outside edge more than anywhere else.

Asked them if they could check rear Alignment after they'd fitted the tyres.
Was told it's pointless as they can't be adjusted.
Said they see it all the time on French cars.
At least they didn't sting me for the test fee knowing they can't do anything with it.

I have to say, having thought about it, I am convinced our old Touran wore through tyres much quicker than any other car we have had.

my old A3 Quattro used to rip through tyres. ~10k a set. My outback driven on same roads at same speeds is about ~30k a set.

also, have you actually looked at the tyres, the garage I use have some fancy scanning thing that can't seem to cope with tyres like a cross climate with diagonal tread rather than linear. it reported all my tyres as being severely worn when they really arent.

Tyre pressures too low would be my first call. (Possibly coupled with aggressive cornering.)

have you actually looked at the tyres,

Believe me when it comes to spending money on stuff that's not a bike I look very closely 🤣

It can't be adjusted, but it can still be out and may need parts replaced.

tires wearing on the outside edge - which parts would you think about changing on a torsion beam ?
