Today, I got my car from the dealer and service adviser said rear tires left 2.0 mm thread left whereas front tires had almost twice as much tread depth
I will be plain with you , I mostly like to enjoy rapid launches and always use S mode and have the ESP light light up and appear .
However, I presumed ESP could save the tires and prevent them from looking like slick tires
The car is RWD , tires are Michelin Primacy HP 245 / 45 / 17
I have put roughly 18500 miles since I bought the tires .I don't know what to do , keep them as is or rotate from rear to front to optimize wear and tear .
Rant is over
Have a safe drive

 

Man, it is too late. 2 mm is at the minimum tread depth for summer tire and at that already is a compromise in heavy rain. Moving the worn out rear tires to front would be very risky in rain.


You need to rotate every 5000 - 6000 miles to keep wear even on the tires. You basically have worn out a set of tires at 18500 miles but if you had rotated them you would have 3 mm tread left on all tires, i.e. you could drive another about 3000 miles on these tires. This would get you to around 21500 miles that is not that good anyways but typical for Michelin tires.


What comes to the ESP saving the tires. Yes, it does not let you plain smoke them but remember that every time you see the ESP light blink you experienced a slip. ESP is reactive system. It does not do anything for you before a tire slip is detected, i.e. before it "saves" your tires slip already happened.


A system that could save your tires would read all sorts of info, like air temperature, road surface temperature, tire surface temperature, measure axle weights, know exact tire rotation radius, have tire rubber dynamic behavior programmed in the system, know the friction coefficient between road and tire etc. etc. .... and then calculate from all of the info the amount of torque the engine is allowed to put out to the drive tires not allowing them to slip at all.


Simply said impossible so reactive system it is and with that the tires will wear more on the driven wheels.


Now, what to do.


Best option is to get the whole set of new tires and if I was you I would not get Michelins.


Option two is to get two rear tires of the same model and keep them in the rear. They will be almost gone when your fronts are done and then get the whole new set of tires preferably not Michelins in my opinion.


But man, just get the whole new set. Your life is worth it.
