OK tried a seach to see if anyone else has this issue....but can find anything. Doubt I the only one though...

I've notice my DRIVERS FRONT tyre is very warn on the outer edge athought still 4mm at least everywhere else...
I have a mate that used to own a tyre company and he said take it back to dealers...so I did!
They said it was tyre pressure...which having "helped out" at said mates garage I know to be wrong...
If tyre pressure is to hight your tyre will wear more in the centre...not enough and it will wear on "both" outer edges...mines just on the outer edge...
They kindly toped up and checked all tyre pressures to correct level and on I go after a heated chat about if I have to replace the tyre when theres still 4 mm left because the very outer edge has gone through YOU'LL be paying for the tyre not me.....

Anyway..I was parked up at a customers the other day and notice why....on full right lock the outer tyre is "rubbing" on the inner wheel arch...this looks to all be seated correctly though, so its not like its come away or anything...

Obviously I'm going to ring up the dealers again and explain that "I have found the issue" (and not their technician LOL)

But wanted to know if anyone else with 19" standed fit alloys has had this issue...and if so what was the fix??
It only had 5000miles on the clock when I got it (Ex Demo Car) so could it have had the wrong tyres fitted...i.e. too high a profile???

Thanks as always...

Hello is there sign of wear also on the inner wheel arch as amount of time on full lock shouldnt cause the amount of wear you are describing. I would be more suspect that camber on that wheel is out, due to potholes or other wear. Get garage to carry out a full wheel alignment check .

 

[R055Y]

There is but only slight...the Garages argument for Camber was the car would pull or steering would not centre etc...but the car drives dare I say it and temp fate, bob on in every way...but yes...agree it will be one of the things the garage MUST check...

 

[HoneyMonster]

No ties with the company mentioned, but they are offering free wheel alignment check may be worth popping in before trip to VX

Has the vehicle been in a bump in the past?

I had a similar problem with an Avon Z3 tyre on a jaguar. Changed them for Pirelli tyre and sorted the issue, but that was on both front tyres.

Defiantly sounds like an issue you need to talk to the dealer about.

I don't have an issue with the tyres rubbing but both front are worn on the outside but that's probably due to me running them softer at 35psi. I am due to replace them when I take my winter tyres off. I have had pretty good milage out of them probably around 20k when I took them off. I still have a bit more tread on them and I could put them on the rear for a few months but I'm just going to replace them.

Hi I have the same problem. Had my antara with 19 inch wheels for 3 weeks now and the tyres are wearing on outta edge, took it to have tracking done yesterday and it was 2mm out.....any suggestions appreciated please

The wider the tyres get, the more difficult it is to get even wear across the tread. Modern steering geometry is pretty advanced as is the equipment for checking it but unfortunately fashion has come into the picture and fashion dictates that you have the biggest and widest wheels in the neighbourhood. It came from America, the old saying that if 4 vehicles are stopped at a 4 way stop sign, the one with the biggest wheels gets to go first.

Outside of front tyres wear due to the power steering this is why it's recommended to rotate your wheels. Oh but don't forget to reset your TPMS

Hmmm. My last set of front tyres wore out evenly and lasted 27,000mls. Never heard of power steering wearing the edge out. Maybe the steering geometry is out.

Hi Chris
Even my transit has power steering and has only done 23k sorry my mistake should have been 32k not 23k and has signs of outside wear on front tyres see below

That's a seriously worn tyre flor 23,000 miles BJS, probably looking at 3 penalty points right there if caught. Do you drive this van very hard? Seems to me there must be something wrong with your alignment or something's going on.

Hi Victor
My mistake should have been 32k not 23k I thought yes going to need two tyres for front took van down to quick fit as van is company van under a Auto lease but they say no got a few thousand miles yet before they need changing ?????
It's got its DVSA annual check coming up.
And hay Victor it's a white van

How does the power steering wear the tyre edge? I thought that it just assisted the steering action of the steering mechanism. Is it because the newer PAS is electric and not rack and pinion and assisted?

 

[Bigjohnsparky]

Iam no tyre expert but
I'm going to go with too much toe-in. That said it's a fairly common wear pattern on largish front drive cars as the stock geometry is often set for straight line running and traction as they aren't expecting enthusiastic cornering. If you live somewhere with lots of roundabouts you can easily wear the outside edges first.

I get that,but how would power steering cause the uneven wear?

Power steering doesn't cause tyres to wear one side or the other, it only provides assistance to the driver to turn the wheels. This applies equally to hydraulic or electrical power assist.

I'd have said not enough toe in BJS but I'm happy to be corrected if I'm wrong. As it was explained to me many moons ago, car front wheels are tilted out at the top (positive camber) because we learned back in the Roman days that cart wheels tilted out at the top made the wagon easier to roll. But two wheels fixed to the one axle and tilted out at the top will tend to run outwards, away from each other and wear the tyres on the outside. To counteract this, the wheels are "toed in"

You can also have negative camber which is better for sports set up so toe out would be the way to compensate for that.

This is a real oversimplification of he complexities of modern steering geometry. I'm no expert in it but I'm no mug either. I'm fully aware of scrub radius, caster angle, toe out on turns etc but don't want to turn this into a high tech jargon post that just makes your eyes glaze over. There's plenty of such articles on the web.

Yes Victor you are absolutely right
Toe in, Toe out, and Toe down is the cause of main tyre wear, not forgetting the road surface

Toe down? Hoe down? or BJS rapping????????


Oh no, toe down = foot down, now I get it

You're right, probably the single biggest factor in tyre wear.


PS I'd still get them to change those tyres, it's not their licence that's on the line. I'll bet if it was a privately owned vehicle instead of leased - and you were paying for it - they'd be falling over themselves to change them.
