Customer Reviews
I replaced 2 tires every year either front or back so it’s a little frustrating with limited options for this model Mercedes
These tires on my 2017 Shelby GT350 are perfect for the street and extremely spirited driving.
These tires are considered TOP in their class for super high-performance vehicles.
Pretty heavy and sticky so expect MPG to drop a noticeable amount. Holds curves and braking very well, plus doesn't spin much on my 265HP FWD sedan on acceleration. Arguably, overkill for an A to B driver, but I do like not having to "drive around" the tires... I can just do what i want and they're ready to do whatever i ask. I used to track my car, and I don't think these would really compete with true 200TW but these are great for regular roads
