I find it very hard to comprehend that a tire store could possibly have tires on the shelf for 7 years.

I think that you would have a very hard time convincing Tire Kingdom in Tampa Fl or the BBB that something shady hasn't transpired since 2008.

I can only see 2 likely scenarios.......... 1. A very crooked employee at the tire store pulled a switcheroo........ 2. Someone saw your trailer parked somewhere, and switched his old tires for your new tires and you never noticed (maybe in a storage yard???).

In any event, if you got that kind of service out of 7-year-old trailer tires..........I'd like a set of those (only not 7-years-old). I sure hope that you had a chance to thank that truck driver......
