Can anyone confirm if I do need all new tires?
I have a Cayanne and instead of Michelins, to save money I put on TOYOs, they were appropriate for the car. But one year later 18,500 miles, I got a flat. Everyone says since the car is all wheel drive I need 4 new tires. Toyo did not think that for everyday driving the toyo tire would be the right ones so they suggested I go back to the Michelins, which are very expensive.
So do I need 4 new ones, some non porsche owners say I do not.
Thank you.
