Dear Mr. Goodyear:
I am disappointed in your tires. What you see here is a tire with only 200,000 carefully driven miles on it. I can asure you that I checked the pressure daily and rotated them once a week. I noticed a crack forming at 150,000. At that point I made sure to drive at a maximum speed of 30 mph to protect your reputation. Alas, the tire is now a total loss. I expect that you will honor your warranty and replace the tire - and wheel at no cost to me, your loyal customer.
Sincerely, Hans
TIRE PRESSURE
If I could bring your attention to the right-side tires of this Porsche 911 GT3 RSR, you will see an incredible amount of pressure being applied due to the speed at which these cars take turn 5a. Tires are mounted with negative camber so to keep traction at a maximum. While it helps the outside tires, it makes the tires on the inside roll out.
