I have excessive wear on the outside of my front tyres on my 4x4 Edition 2.0l tdi dsg and thought I would pop the car into a local tyre specialist to get the tracking done. They told me that with all the electronics such as lane assist etc they couldn't do it as it would cause the dash to light up like a christmas tree so I have contacted my local Skoda dealer and am waiting a reply as they were unsure, has anyone else come across this problem?

Yep my fronts have done the same , was just looking at options to change them ,surely just checking the geometry can’t cause any issues ,the only problem I see is if it’s adjusted the steering angle sensors my have to be re set 

If a workshop does adjust something after a wheel alignment check they are supposed to recalibrate any ADAS sensors. i.e. the radar for cruise control and the lane assist camera. The place you went to obviously haven't invested in any ADAS equipment, its quite expensive and every manufacturer has different calibration boards that need to bought.

If you imagine a straight line coming out the front of the car that is picking up objects 200 metres down the road, if you turn the car slightly this will affect where that points quite dramatically.

Yes but you are not turning the car, not even slightly, you’re still following the same course you would have been before the adjustment.......just that now you aren’t scrubbing the fronts........?

Both my fronts have done the same at 15k. Must be common to the 4x4. Annoying as there is still plenty meat left on the rest of the tyres.

My Yeti did same

 

15000 and fronts bald on inside and outside edge but 4 to 5 min inside

 

tracking checked at 2 dealers

 

1 blamed low tyre pressure despite it not being low

 

the other said tyre type does not suit car

 

 

I agree, I think its the tyres as I've always correctly set my tyre pressures. My is running Bridgestones.

You can have a 4 wheel alignment check done by a specialist just for the 'scores on the doors'  no adjustments done,

but it will cost you and take the result of that to a Main Dealership if they have not the equipment and say, 

you need to get this alignment sorted out, if you have not all the gear and more than an idea they can call your friends at the Audi Dealership how seem more interested in cars and having them perform as they should.

 

If the tracking or alignment is out then that is not unusual with UK Imports (right hand drive cars), it is how they left the production line and not always down to hitting kerbs or speed bumps too hard as often will be suggested at a dealership.

If one wheel is not running straight this could pull the car out of alignment and cause the tyres to wear.

This is why an ADAS calibration is required after any suspension adjustments.

There are 3 values to look at on a wheel alignment check; camber, caster and toe. Any of these can affect the handling and tyre wear.

SUV tyres can wear on the outside just because there is taller weight making the car roll over onto the outside of the tyres.

 

Not sure about that. To drive in a straight line both wheels would have to be at the same angle. That's why if the tracking is affected after say hitting a pot hole you can still drive in a straight line but it will be evident by the steering wheel no longer being straight and the tyres scrubbing.

You are trying to drive straight or go around corners on a road, in the UK or in some other country.

They are not like a Airport Runway,  not horizontal / flat they are cambered roads. 

 You are not running along the white line of a single carriageway road.

 

The springs might not be handed but the suspension and steering and tyres & tyre runout need to be correct for a car maybe with just a driver in or at maximum gross weight.

It is not rocket science just Motor Engineering, 

get the alignment done and the adjustments done where people know the correct settings / readings. 

I’m still not convinced that a very expensive check is required, each and every time, just because the front wheel tracking has been tweaked a smidge.......the car is still going the same way, scanning the same road.......only difference is the driver is not applying weight to the steering wheel to compensate.

Out of curiosity how many miles have you driven?

I've just driven around 3500 miles in my manual 1.5TSI EVO Karoq SE fitted with Hankook 215x55 17R tyres and already I can see that the outside of all 4 tyres are wearing more compared to the rest of the tyre which makes me wonder if alignment + tracking are fully checked on cars leaving the factory, I don't know if dealers are meant to check this during the PDI?

 

My local skoda dealer hasn't the equipment to do the tracking, I had to involve Skoda UK and they have got me booked in at a local vw garage who told me they couldn't do Skoda when I rang them. 

I've emailed a manager in the executive office of SUK regarding the early wear on all 4 tyres, it will be interesting to hear what she eventually comes back with ...... doubtless it will be another charateristic of the Karoq.

FWIW my tyres have worn very evenly all round. The tread is level all the way across after 21k miles. The rears have worn maybe 1mm less then the fronts. Tyres run at 38psi in summer and 34psi in winter. They are now down to 2.5mm of tread and will be replaced next month. My car is a Karoq 2.0TDi 4x4 with 225/50 R18 tyres, still on the OEM Bridgstones.

Sounds like your cars have a fault or am I lucky?

corrected mileage. 21K not 22K

Had to get my front tyres replaced yesterday at 16.5k miles due to excessive wear on the outer edges. When the garage took the tyres off, they were also worn on the inner edges but not as much as on the outer. Garage changed the tyres and did a 4 wheel alignment (Hunter equipment) check which showed that everything was fine.

 

All the guy could suggest was to increase the tyre pressure on the fronts to reduce the tyre roll which appears to be happening on the edges. I usually run my tyres at 2.4 bar but he suggested increasing to 2.6 bar.

 

What do others run their tyres at and are you experiencing excessive wear on the edges?

Yesterday after washing wifes car - i noticed from tyres are at around 2.0 to 2.5 on outer edge and around 5 to 5.5 in middle. (2.0 TDI 4x4 DSG)

 

Car is just 3500 miles...

 

So increased pressures to 2.7 Bar from 2.4 Bar to see if that helps.

 

Will swap to Winter Wheels and tyres in about a month also...

 

Then next March.. will put Summer wheels on but swap Front to Back and Back to Front.

 

And I thought my Yeti ate tyres at 15,000 miles.....

@RichardPB

My opinion.  Maybe worth nothing but then others can disagree.

 

Increasing the tyre pressures would be like an Eco pressure.

Less tread on the road, meaning less friction so less grip. so less safe in the wet, cold etc and defeating the point of having a AWD model in the first 

 

What brand of tyres were on the car, and have you fitted like for like?

He said that the tyres weren't sitting flat on the road because the wear in the centre was significantly less than on the edges. To make the tyres sit flatter and provide more contact was to increase the pressures. He did however say that it would be trial and error to increase the pressures to reduce wear but not reduce contact.

 

I was running OEM Bridgestones and have gone for similar Bridgestones again as not much choice and got them for a good price.

 

Will be interesting to see if the increased pressures do make a difference. 

@RichardPB

Are these Bridgestone Deuler?    So they should be cheap if they are. i have seen them worn on the edges on nearly new Ateca 4drive & Suzuki Vitara,

IMO the spawn of the Devil.

Does indeed sound like some form of alignment issue. Although how many miles do you expect to get from your tyres? I'm happy if I get 15>20k out of mine. 

Mk2 face-lift octy vrs used to have issues with odd rear tyre wear, usually excessively worn or "chamfered" on the in side shoulders, mine was checked by main dealer and by an independent and the car was found to be within tolerance but only just. So I had the independent shop adjust the car to the other end of the limits (less camber) which improved things but not totally eliminated. Skoda wouldn't honor a thing as the car was within spec, or in my case anyway which BTW was less than 7k miles and 1 year old at the time. 

Having said all of that there may be an element of under inflation going on for those who have excessive wear on both shoulders of the tyre. If the tyre was over inflated it would then obviously wear out the centre of the tyre first. 

Of course cars are being supplied with ever larger/wider tyres and the tyre pressures and overall wheel alignment must be a trade off between efficiency, actual tyre wear, grip and good ride/handling across the vehicles whole speed range.

I have just replaced my original Bridgestone tyres at 22k miles. Worn evenly across the surface and even front to back. They were worn to 2mm. I have run them at 38psi from new if that helps, YMMV.
