Offset tire footprint: on semi-icy roadway

Post by 93Regina » Mon Jan 13, 2020 9:32 am

Driving on interstate roadway with drizzle and below freezing temperature, there were some slick spots on bridges and roadway.

Traffic was flowing around 45 mph, and higher, but there were semi-trucks, pickups, and cars ending up in ditches, guard rails, etc.

For light footed vehicles, like empty semi-trucks, pickup trucks, and vehicles with oversized tires, it would be expected for them to have driving issues on slick spots.

During afternoon hours, I was pushing the speed at around 55-60 mph, when possible, even passing up a highway patrolman, but I was tracking where traffic was flowing in my 1993-940. I perceived a few slick spots, but kept the steering wheel essentially with very small movements...very small.

I've never measured the total tire width offset from say outer front wheel tire to inner side of rear tire on same side, but I suspect this assisted in a pinch better traction than vehicles with both front and rear tires tracking in same path.

I was not using cruise control, but I suspect a few of those vehicles which 'crashed' were.
