Last night the Piper family was on the road after dark. Suddenly there was a tire tread stretched out in front of us, on its edge, so the broad side was facing us. We were in the right hand lane, being passed just at that moment by a semi in the passing lane, so swerving was not an option. I just braced the steering wheel and we hit it. Big WHUMP, PiperCub in the back started to cry and needed reassurance, but we survived - but I’ll take the Pipermobile in for a check-up as soon as I can.
But it got me thinking - how do tire treads come off like that? You see them on the highway from time to time. And how can the vehicle that lost a tire tread continue on? Are they from semis, with so many tires that one lost tread doesn’t matter?
