Sorry for the confusion, but for one, they aren't on a boxster. Also, the inflation specs are specific for the original factory tires/and wheels, which can change when moving up in wheel size. The tires were on the car for about 8 months, which is well under 5 years, and this is not a result of dryrot. I have the receipt of purchase necessary and i was right around 8000mi. on the tires. I appreciate the fact that these questions are being raised and i understand the tires are a consumable product, but this tire was not worn out. As i said, this has been my experience, ongoing since December.
