Is there something about ST tires that don't last as long as light truck LT tires? The original OEM tires on our old truck lasted 13 years (only close by around town use) and probably would have kept going except when we got a new TT and planned a new trip, decided it was time to replace them.
Are ST tires running on the edge at 65 mph?
That is a good question regarding why ST tires have such a limited lifespan as far as number of years. One of the cars in our family has a set of GoodYear "aquatread" tires that I put on it 10 years ago. The car only sees occasional use, and the tires only have about 25K miles, yet they still look brand new. No cracking, dry rot, splitting, etc. They look as new. I've seen numerous "very old" car tires in use on various horse trailers also, and some of them still looked fine too, other than being essentially worn out. These were "used" car tires that were put into service on the trailers.
One has to wonder if ST tires are simply built to lower standards.
