I was ALMOST certain we were dealing with the same Looney under a
different name - now I KNOW it - and way back then I gave a solution
to the accellerated wear you were bitching and complaining about. AIR
UP YOUR TIRES!!!! Rotating your tires does not reduce the wear - it
just distributes it. A bit more air in the tire will keep it from
squirming/leaning/feathering. So will using a tire better suited to
your bob-sled-run twisty downhill roads.

Since the spare is a different brand, I rotate in the classic four-wheel
II-X-II-X pattern that puts each tire at each of the four corners over a
period of 12K miles (about 8 to 10 months of driving) - and - when I rotate
- I inspect the entire carcass for pebbles & shards as shown here from this
weekend.

To overcome some of the boredom of plucking detritus out of the tread, I
count the objects removed, where there are always more than 50 per tire, so
I try to approach a count of 100 objects removed, some of which turn out to
be this (staple?) shard I found yesterday.

While you intimate that the periodic inspection and rotation of tires has
"gone out of style", my reasonably logical position is that the selection,
mounting, balancing, pressurizing, inspection, repair, and rotation of
tires is a reasonable and rational act that results in increased safety and
life of the tires - partly because removing something like this shard never
goes out of style!

Yup, I posted earlier, before I got down here, this is the same numnut. I
forget what his NYMS were.
