Best Tyres for the Mercedes Benz SL63 AMG

Achilles Desert Hawk . These tyres are dangerous, all 4 inner side walls have split after less than 20,000 kms. Tread wear is equal across the tyre, just the inner side wall failed. Two tyres blew out within a week and disintegrated. It looks as though the wire belting has just busted. I have photos to prove it. I would have attached pictures but I can’t. The top tread is perfect, only the side wall where it met the top has totally failed. It is a structural failure. If you have them fitted take them off.

Let me mention my 2018 SL63 came with Continental conti sport contact 5p, and I found them all around an OK tire, but they wore out in 15,000 km... So I went seeking a better tire, I dont care about wear that much, I spent a lot of money on my car and good or the BEST tires are a must regardless of whether they last 10k or 50k, I saw a lot of good and even excellent ratings for the michelin 4s tire, its new and has some new compound in the rubber that is supposed to give better grip.. I have a powerful car with lots of torque, 668 lb lbs, so when I give it I want grip.. I put them on the rear once the Contis were done... These 4s tires when I first installed them on the rear, I found the grip they gave was incredible ! I was so happy, I could finally launch my car properly, but now with 8000 km on them (5000 miles) they are not gripping nearly as well, I would say they are now worse than the conti 5p.. I have lots of tread left, but for some reason they only grip well on NEW pavement. Anything else other than NEW pavement and I can put my car sideways in 3rd gear with my traction control off, and 3rd gear goes up to 100 mph so that is very scary. I have to say I am disappointed the performance of these tires has diminished so very quickly, and since they have lots of tread left I find that I am going to have to replace them already. They are also a bit soft in corners... Thinking of the Continental 5p again, or perhaps the continental extreme contact. Sport cup 2 perhaps???? I just know I will not buy the 4s again.

I thought these tires gripped enormously when I first got them but after 8000 km they are not gripping nearly as well and yet have shown little wear. They are wearing far better than the conti 5p my car came with, but the 4S seem to be very very slippery on certain types of road pavement, if its a bit of a light grey very smooth pavement with a bit of a shiny look, the tires feel like you are on ice and will cause the car to loose traction even under light acceleration. Im not sure if its the rubber compound, but I think i will try another type of tire next time and compare on the same roads to see if I can duplicate these slippery conditions.
