Had my first over the weekend, 2014 E350 with the AMG wheels. Going only about 5mph in the dark and hit a pothole (nothing so severe as to make me stop and look). Got where I was going and parked for a couple of hours, came out and the light on the dash was illuminated. After a couple blocks I got a message to check my tires and showing the left front had 15psi, then 12psi and then 9psi. I pulled over and put on the spare. Next morning took to Discount Tire and they said the sidewall was pinched, luckily they had a new tire in stock (no damage to the wheel). The car has 5500 miles on it.

When they asked if I wanted insurance on the rest of the tires I said absolutely! If a small pothole at 5mph can cause a failure I'm guessing I'll get more.

I did notice that they pressured the fronts to 36psi and the rears to 42psi. Prior the dealer had set them all at 32psi. I wonder if the lower pressure increases the likelyhood of a pinch on the sidewall?
