Are these tyre cracks dangerous? Never seen them here before
Discussion
Hello, does anyone know if these cracks are dangerous? I've never seen them in that location. The sidewalls are fine, and the rear tyres are totally fine, but on the front tyres there's cracks running around the rain channels of the tyre, mostly on the inner side of each front tyre.
Thank you for any advice that anyone can share on this!

The tyres are Goodyear Eagle F1 Assymetric 5 (around 2 years old, only covered around 8k miles), and the car is a 2004 Jaguar XK8 coupe.
It's a shame as well because these tyres have been amazing, great handling and really comfortable at the same time.

Cracking between the tread grooves, especially around the circumference rather than across the tyre, aren't as worrying as cracks in the shoulder or sidewall. It indicates a hardening off of the rubber rather than some nasty structural failure of the tyre. PH is incredibly trigger happy when it comes to recommending new tyres because of course everybody here has loadsa money etc.
It won't, or at least shouldn't, fail an MOT on it. I wouldn't expect the cracks to get suddenly worse or to cause a blowout. It's a 'monitor' situation IMO.
If you bought the tyres, or you at least know who supplied them and happen to have an invoice etc? You could have a conversation with the tyre fitter who will ask the manufacturer whether they want to offer a replacement, discount etc. It's worth looking into this ASAP if you've had them 'about two years'. Sometimes if there is a known problem with a particular pattern or batch I've heard some manufacturers can be surprisingly helpful.

Ok that's good to know as the only cracks are around the circumference like that, the blocks, shoulder, and sidewalls are all perfect looking.It won't, or at least shouldn't, fail an MOT on it. I wouldn't expect the cracks to get suddenly worse or to cause a blowout. It's a 'monitor' situation IMO.

It's just passed it's MOT with no advisories.
I've just contacted Goodyear through their website/email to ask about it, so who knows maybe they'll offer some sort of credit towards replacements!
Thank you!

Damn, although it was literally just MOT'd and passed with no advisories.
I guess I'm maybe more cautious than some, I put four new Pilot Sport 4 S on my XK, the previous owner had been content to roll around on cracked Dunlop Sport Maxx on the front and Accelera Phi on the rear. They didn't seem fit for a 300bhp V8, so went in the bin. Continental tyres say,
"Groove cracking symptoms as shown in the photo are usually superficial and may be caused by a variety of factors other than the tire itself.
"These groove cracks (also called stress cracks) are mostly caused by improper inflation pressure, excessive heat, over loading the tire or high ozone level in the environment."
I certainly wouldn't panic. MOT testers know what they're looking for. The structure of the tyre is mainly in the cords and belts with the rubber holding it all together and providing the tread. If you've ever tried to saw through a modern car tyre they're incredibly tough. Nonetheless, any glimpse of a cord and you'll get an MOT fail.

I would say Continental are just making excuses there to try and place blame elsewhere."Groove cracking symptoms as shown in the photo are usually superficial and may be caused by a variety of factors other than the tire itself.

Modern tyres crack,, and it really is ridiculous how bad some are. And it's so common, there is no way those things are to blame, otherwise it would have been happening for decades.
In reality, it's getting worse this last 10 or so years
So clearly they're changing something with the rubber, designs, whatever. Because everyone cannot suddenly be over inflating, over heating or overloading the tyres.
As for ozone.....can't comment on that, but sounds a little desperate

Agreed it does sound a bit like they're throwing out every reason under the sun to avoid the blame.Modern tyres crack,, and it really is ridiculous how bad some are. And it's so common, there is no way those things are to blame, otherwise it would have been happening for decades.
