One of my tires has a broken tread for unknown reasons. The other 3 are in good condition. The tires are only a year and a half old.

What drivers say about their 225/40 R20 tires
The most recent owner reviews fitted in this size, in their own words.
I have these tires on my Tesla Y and till now, I have had 3 tires changed before their end date (first time at 25k km’s) the foam inside would come loose and create some sort of centrifuge effect which stopped me from driving faster then 100kmh, one time for 1500km’s as it started in the south of France and I had to go back to the Netherlands. I don’t trust these tires at all anymore.
got over 50K fronts worn more than rears - good grip on corners and in wet and on gravel roads - mostly run on blacktop and distance of 50 - 200 km trips. Probably have another 5K before needing replacement
Thought that these low profiles are a lot noiser than Kuhmos I had on Toureg but have got used to the road noise on this Tiguan R series.
I use P Zero R20 run flat on a BMW 730 Li for a year. The tire was one year old when i bought it. Both tire has a cut insides which is very dangerous for a high soeed tire only after one year and Pirelli Malaysia said that its not their reaponsibility.
Very very poor tire quality and brand promise. I am really surprises. I thought i paid for the best tire. Dont buy.
Best tires I have had my van for years so good in fact I had four fitted to my Range Rover today.
Bought a car that came with 4 of these tires and oh my gosh they were just AWFUL.
EVERY SINGLE SIDEWALL HAD CRACKS which prompted me to replace them immediately. Dry grip was OK but wet grip was non existent with constant wheel spin under light acceleration.
Braking was a different story. It would cause the steering to snatch violently in the dry (I've had replacement discs, pads and calipers)
I've noticed that some others have mentioned that they thought their wheel bearings were failing - I had exactly the same issue and since replacing the tires, this has completely gone away.
If you value your life or anyone else's in your car, avoid these tires at all costs.
The only reason I have given these tires a 1 for wear rating is due to the sidewalls. There was still around 5mm of tread left on each Tire at replacement.

Tried Cooper and will buy again. Wear rate is brill. Have used in the past Pirelli, Continental,Toyo and Michelin. Cooper is half the price of Michelin for similar performance and use.
Only changing tires early as down to 2.5mm and it's the rainy winter season.
