Wheels/Tyres: perished tyres

[minstrelblue]

my xc90 was fitted with 4 brand new nokian z line suv tyres in may 2016 and supplied from oponeo.co.uk and having just completed no more than 15k miles in that 2 years i was given an advisory on the MOT about the general state of the tyres, the tread depth was an easy pass but he had concerns about the cracking between grooves throughout all 4 tyres. the tyres have been regularly maintained with correct pressures, driven regularly, not left for long periods of inactivity or exposed to extreme weather, they've just been used for daily sensible driving on uk roads. The tyre date on the sidewalls has been verified to state they were manufactured in may 2016 so they have not been left on the shelf long before their sale. so i've contacted the supplier to enquire whether these tyres are under warranty for defect [ which i believe they are] and they've asked for photos. is this a manufacturing defect we'll have to see what they say but i expect they'll argue and refuse to accept its a fault

Would be useful if you could post the photo's - it's most unusual to hear of people complaining about Nokians on here.

I have stopped buying Nokian tyres for this very reason. This is a known issue with them. Send Nokian tyres an email with pictures as well as your supplier. There is a link on their web page. I was successful in getting a warranty claim for the ones fitted to my wife's car but I had to return them to tyreleader who then took months to send them back to Nokian. I didn't bother when the same happened with my car as they were pretty much done.

I find Michelin are the worst for side walls cracking, the tread never wears out as the side walls always crack with 60% tread still left

I've never experienced this issue with Michelins, Ive been use cross climates for a few years now.

I have seen one other post on the forums about Nokian Z SUV tyres cracking, and have never heard of any other problems. I remember looking at the pics posted, and my opinion was an over eager tyre sales opportunity being chased.

I'm on my 5th set of Nokian tyres, WR SUV's, Z SUV's (original and version 2) and Weatherproof ... never experienced any issues .... so I'm not sure there is a "known issue."

I must agree about cracking on Michelin and Dunlops,
I have experienced this in the past.

Some pics of the issue would be helpful as its was a MOT issue this time, so unless he is very wet behind the ears, or was also trying to sell tyres I'm interested in the development. Also out of interest, whats the DoT code from the tyres, as you may have had them fitted in 2016, but they could have keen kicking about a warehouse for several more before that!

I'm not sure how true this is but when I had another vehicle valeted professionally, the guy alerted me to some cracking showing on the side walls of the nearly new tyres saying that the car had previously been cleaned using acid or some other corrosive cleaner which had damaged the rubber. He went on to say that at many of these pop up hand car washes they use industrial grade washing products which are not diluted correctly, great at shifting much quickly and without much effort but are highly corrosive which can be bad for tyres and other parts of the car. Extreme care should be taken when using acid based 'over the counter' cleaners for alloy wheels too. He also believed that some of the tyre dressing sold to enhance the lustre of your tyres can have detrimental effects.
This guy may have just been touting for more business but he did seem genuinely concerned with some practices undertaken by car washing companies and the damage they can do to people's pride and joys.
Just a thought if tyres are going bad?

It would be great to get a set of tyres that would last 2 years!!

I bought a set of 4 nokians a few years ago for my xc90 and had the same problem with cracking between the tread. There was loads of wear left on them but I had to change them. haven't bought any since.

will send some pics asap
