uhh... no!
True...they only picked up larger rocks.
I'll bet you lay awake at night dreaming up this crap.
You are NUTS. If you are driving in icy/snowy conditions, the finely siped tire is a NECESSITY. If you have STUDS, that is (possibly) a different story. Carbide studs damage the road, particularly if you spin the tires. Nylon studs do minimal damage. Gravel stones, sand and pebbles????? NEVER.
Makes you wonder what he does for a living, consider the super-accurate speedo... sure hope no one pays him to be an analyst, of any sort.
My bet he assists in election campaigns... strong link between denial, obfuscation, nit-picking and politics
Those modern tire provide much better all weather traction and save lives. By the way I seldom see pebbles stuck in the tread of my Michelin Harmony all season tires. What inferior tires are you referring to.
ROTFL!!

Hey, this is first rate comedy! Better than Click and Clack!

Sunshine and rain do more damage.
Ban the weather.
May be they should start building roads out of recycled rubber from tires, then the roads could throw the stones back in retaliation.
I don't know where he's getting this from... IME old bias ply tire have far more "fine sipes" than the modern radials that I currently have on my cars (BFG T/A on one, Yoko ES100 on another, and some Goodyear all-season POS on a third)

Ever wonder what happens to all the rubber from the tire threads as the tire wears out...millions and millions of tires......every day...year after year....
Ice and road salt does far more damage to northern roads than does tires, sun, rain and pretty much everything else put together. Only a burning car is worse on the asphalt than ice and salt.
Obviously, this doesn't apply to southern climes.

Dunno about THAT, but there's no doubt that bias plies were far more destructive to secondary roads....
Geezers, please think back to where every curve became rutted... due to tire resistance.
In my area there was a 750 foot portion of concrete built to interstate standards that lay dormant for 25 years... blocked off, it had no vehicular traffic, and negligible salt on it. It only had rain and freeze/thaw.
By the time the roadway got extended, it was a broken up mess.. they had to tear it all up and lay new concrete.
Yep, the freeze/thaw is the big killer, but salt isn't great for concrete either.

I seem to recall a project in Ontario a few years ago where some experimental sections of road were laid with mixtures of asphalt with granulated tires and/or sulphur. I guess it was not successful because I have not heard any more about it.

A proper observation: "I believe that our recent experience with "Nomen Nescio" was an attempt to waste our time with unreasonably argumentative rants that started ..."
The Freeze / Thaw issue is only so when water penetrates the surface. Salt is only an issue where it facilitates the melting of snow into openings in the surface. Smooth, thick concrete will easily last
20+ years.
I don't wonder, I know it becomes particulate matter we all get to breath, free of charge. Excepting of course the rubber that is "burnt" into the streets in front of schools.
Oh yeah? You calling me a liar?
