My old bias ply tires would "hunt" for the ridges in the road. If the road had the 2 grooves worn in it, my '48 3/4T would lurch to the side (sometimes almost violently) to get the tires on the higher points above the grooves. At one place in town, it would scare the heck out of a passenger but I knew it was coming. It would only go to the high points and then stop. There was no danger in going into the ditch.
When I got my 235/85R16 Michelin's, all that stopped and I could bring a cup of coffee with me to work.
