Checking the tyre pressures a few days ago on my 2020, Kamiq SEL, I noticed what seemed to be an unusual pattern of wear on the front tyres - see photos attached - and I wondered if this was usual for the Kamiq. I check the tyres regularly, both using my own gauge and the machine at Sainsbury's, and the pressures are consistent around 2.4 to 2.5 bar, although in cold weather on one occasion, the reading was 2.3 bar.

 

 

What tyres? 

 You do not mention how many miles driven.

Move the wheels / tyres front to rear and get some more use out of them.

 

 

Maybe it will become quite common on Kamiq's.

Apologies, I meant to include that.  Tyres are Goodyear Eagle F1 Asymmetric 3 and mileage is 12,355.

Luckily you have spotted it before it has got badly worn down in one part of the width.

 

As @roottoot says get them swapped front-back asap.   It might also be worth getting the front tracking checked, but I think it is probably cornering forces.

 

Your dilemma is how long to keep them, there are not the best tyres in colder weather, and really you would be better with all season tyres (or even a set of winter wheels and tyres if you live on moors or Dales).  
 

As they are summer tyres try and keep them until mid November (May as well get some more mileage out of them), but beware all season tyres tend to jump in price as weather starts to cool from mid September so sometimes better to order them with fitting date 2 months later to get better price, whilst  wearing existing summer tyres for as long as possible.  If you live on coast where it is milder might get through the winter with them, but only you will know how much you drive in frosty or cold sleety rain.

Thanks for your comments.  Cornering forces seem unlikely at the speeds I drive and as I'm on the coast, winter use seems possible, but we'll see how things go.  I have passed the photos to my dealer for their comments so I will post their views here.

 

Searches on the tyres and their wear rate haven't produced anything useful, so I asked a different question - "what is an asymmetrical tyre?" and here is the answer:

"Asymmetric Tread pattern

Asymmetric tyres effectively mix two different tread patterns on the outer and inner edge of the tyre to provide a dual benefit to the driver. On the outside edge, the tread pattern exhibits large tread blocks which are designed to provide good dry traction and handling thanks to a larger contact area with the road. Meanwhile on the inside edge, the tread block is much smaller to provide better wet grip, and an increased number of grooves to help disperse water on wet roads and reduce the risk of aquaplaning. This effectively means the tyre is built to provide great all-round performance in both wet and dry conditions.

Asymmetric tyres can be placed on either side of the vehicle but the larger tread block must always be on the outside edge of the tyre in order to work effectively. That’s why asymmetric tyres have words like OUTSIDE stamped on the sidewall to ensure they are fitted with the tread block facing the correct way."

 

I'd certainly noticed the asymmetric tread pattern and that the grooves on the smooth strip in the photo were fewer and much less pronounced than the other areas of the tyre (by looking at the rear tyres).  Presumably, therefore, this explains, in part at least, why the grooves are now worn away completely.

 

Have you thought about tyre pressure? The info on tyre pressures inside the fuel filler flap says that the tyres on my Kamiq should be 2.5 bar which equates to 36psi (unladen) and which you say you are running at. However, I’ve looked at a number of tyre websites and for my specific vehicle every single one says 30psi which is a significant difference. 

There are various websites that show for the various tyre sizes of tyres.

Front and rear 30 PSI

& Front loaded 35 & Rear Loaded 38 PSI.

Is it just the one front tyre displaying the uneven wear or both front tyres? It looks like a front left side in your pics.
 

Regarding cornering forces, it doesn’t need to be high corner speeds to wear a tyre shoulder.

Do you regularly negotiate the same mini roundabout? A sharp swing around can easily cause the sort of wear your having. Or perhaps do you turn right into your drive the same way every time?

Also wide(ish) low profile tyres are juggle with pressure v load v wear. But as others have said keep rotating the tyres front to back to get the most out of them.

The top photo is nearside, the bottom offside.  (I had assumed that the name of the file would appear with the image.)

The wear is on the tread, not the shoulder.

What is not commonly understood by some, is that a tyre designated Sport is not by definition a long life touring tyre.  They are designed to grip more when  warm (through enthusiastic driving).

 

Because the laws of physics mean it is not really possible to make a compound that is both grippy when warm, and also not rock hard when cold, it results in excessive wear when a summer tyre is used on abrasive surfaces in cold weather eg winter (and I don’t mean gravel tracks, it is the cheap road surfaces with sharp chippings bedded in wet tar), turn a sharp corner on these and you will accidentally scratch off bits of tyre surface.  (the sport tyre will be hard and more brittle when cold).

 

Which is why if you want the car for everyday use all year, (and not shod like a sports car in warmer weather) then fit the best premium all season tyres.

But it's not designated a Sport tyre; the F1 refers to the tread design - see my earlier post - and the tyre comes as standard on my SEL.

So when you say an unusual wear pattern do you refer to the very slight raised band in the middle of your tyres?

No, to the tread arrowed in the attached photo

Ok… so is the arrowed area low or high? If it’s low your running over inflated and if high you Are running under inflated.

As I said in my first post, I have been following the recommended pressures of 2.5 bar and checks have consistently shown the tyres to be 2.4 to 2.5 with topping up as necessary.  An exception was on a cold day the reading was 2.3, again adjusted as necessary.

 

The area arrowed is neither higher nor lower than the other treads; my query arose because it has no tread showing.

But as I said in my previous post the recommended pressures as per a number of tyre websites are not 2.4 to 2.5 bar unless you’re always running fully loaded.

Yes it does; it has no transverse sipes by design but does have a circumferential groove.

Well, it has no transverse stripes now but it did have 12,355 miles ago, hence my query.

Sipes (not a typo) do not always extend the full depth of the tread.

Edited 7 July, 20223 yr by KenONeill

Did they look like this when new?

 

The tyres had to wear someplace otherwise they are going to be lasting forever. 

 They are not bad for 12,355 miles of use.

 

?

How about a picture of the rears?

And the sipes that were there did not extend the depth of the tread, they were on the right hand shoulder looking from the front of the car, and they are not there now.

Effectively, you have posted a picture of the rear tyres, although their tread depth is, understandably, less.

So to sum up then… the tyres have done 12k miles and are showing completely normal signs of wear. End of thread.

Thank you for your straightforward answer, which was what I was after, either there is no problem or there is a problem.  I have never seen tyre wear like that and so, understandably was concerned and had imagined that another forum member with a Kamiq might have had a similar concern and so could provide an answer.
