These look to be pretty tired looking tires that have seen better days. They resemble the discarded tires that used to be stacked behind the ESSO gas station. Back then, times were simple. We often spent hours just rolling tires down the hill behind the station. The stocky, olive-skinned guy who was the boss said, Roll to your heart's content, but just get 'em back up the hill at the end of your fun". One afternoon, we found a couple of huge tractor tires and rolled them to the BIG hill at Gullivers Field. It took us about 20 minutes to get them there, and then we dared each other to 'ride the tire' by climbing inside for a downhill scream. It was a scary 'downhill adventure'. I tried it once, and that was it for me. When I finally crawled out, I was in a state of heightened dizziness and was sick to stomach for the next 20 minutes. It wasn't the smartest of our adventures, but it sure was 'quick fun'!
