Re. Wide Vs Narrow Tires - I rest my case

Not to start this again but I’ve lived in snow country over 60 years. The idea that a narrow tire will punch through the snow and ice into dry pavement is laughable. Tires ride on top of snow and ice. The only way you get to bare pavement is if the salted and plowed it. But hey people will believe whst they want. My vw had pretty narrow tires but my others cars had standard size so I’ve had both. The old style snow tires gripped the snow for traction.

You seem to do well with math. Are you trying to make us think you’re a latter day Sam Ervin?

edit: I noticed in another post that you’re 55 years old. Senator Ervin of NC was retiring about the same time you were born. Check out his participation in the Watergate investigation by the US Senate.

My Avalanche’s tires have alow speed rating.

T 112 mph, I think, but the truck is governed to 99 mph. No one need a 5900lb SUV running above 100 mph! It would easily if not governed.
