What happened to my tyres??!?

[Prancing Hippo]

Any views on hwta has happened to my Dunlop tyres? I have a Cayenne Turbo S, and noticed the wear on the winter tyres attached. It is only on the front tyres. There is less that 25,000 km on these tyres, and I don't use them in summer. The wear is like this all the way around the inside of the tyre on both front tyres.

Thanks. I live out of UK (Czech Republic) where the temperature and snow means winter tyres are a must (by law as well actually). I also do quite heavy mileage on German autobahns, so if dry etc do motor along at speeds in excess of what one would in the UK for example... Maybe it is heat. One part does look like it melted on one wheel, but I did not get a photo of that. Any recommendations on what are the best winter tyres to get for a car like this given what I use it for? Would different tyres make a difference, or do i just have to change my driving style? Thanks.

Out of interest, what's the load and speed rating on the tyres pictured?

I will check, not sure from memory.

The reason I ask, is that looking at Dunlop's website, the speed rating for their "performance" winter tyre is H, which is only 210kph. If you're driving faster than than on the Autobahn, I'm not particular surprised that they're overheating.

That may well explain it...

Continental WinterContacts are V rated on my BMW.

OT - PH will you be attending the Sports Car meet at the Brno Autodrom weekend of 11-12 May? Normally a good day out.

Thanks. Will check them out. Am tempted by Brno if I am around. Race at Brno quite a bit for various races. Slovakiaring this Friday in case you are there - look for Kumiega Racing.
