Michelin pilot sport tires
i have a 2011 mercedes benz s550 4matic, i have been running michelin tires foe over 30 years, i worked in poland in 2016, when i returned home in 2017, i put new tires on all of my cars, on my s550 i decided to go with the pilot sport as3 tires, on my 2006 cadi dts i went with the michelin primacy mx4x tires, on my 2005 nissan altima i went with the primacy tires also, i drive my s550 the least of these three cars, mostly on the weekend and travel, since i installed these tires i have put 15,000 miles on them, and they are worn out, i have rotated and balanced my tires every 4500 miles, and maintain the alignment also. i picked up a nail in my left rear tire and took it in to be repaired that's when the tire tech told me my tires were severely worn, this is a 45,000 mile tire and at 15,000 they are wore out, i will admit that i do not race my car, i purchased it for the comfort that the car offers, discount tire where i purchased the tires and had all maintenance done on tires told me that the y would give me the balance of the tire warranty on the purchase of a new set of tires, they offered the pilot as4 as a replacement i turned them down, asked if they had the primacy in my tire size, they said no, by the way the tires on my cadi and the nissan have more miles and are showing no wear, all tires purchased at the same time, the tires on the cadi and nissan look new, and have 8/32 of thread on them the pilot tires have 2/32 of thread left, i have gotten great service from michelin tires, but not the as3 tires will not purchas another set as3's
