2018-07-11 - Is there any reason why Toyo Proxes 4 Plus all season high performance radials would not be recommended for a Porsche 911 Carrera S? Other than possibly the front tire W speed rating of 168 mph. Never reached by most of us. Or that they are not Porsche certified. Thank you
Assuming the size and load rating is correct, they should be fine. You might find on a powerful sports car like a 911, the all season Toyo might feel soft compared to a proper summer UHP tyre.
