Thank goodness they banned studded tires. I remember Wisconsin's
interstate system in the 1970s being nearly destroyed by all the guys
with studded tires. The lanes actually had 1/2-inch deep grooves worn
in them, from the studs ripping up the concrete and asphalt. It got
down to the rebar, in spots.

Interesting as I've never seen an interstate concrete highway that used
rebar... The only metal in most highways is the row of pins used to
lock the sections together at the expansion joints.
