In Oregon we are allowed to have studded tires for something like 5 months out of the year. First off, I think it is stupid. They should only be legal in certain parts of the state, and if you drive outside of that part you get a ticket. Otherwise, just carry chains. Yeah it is inconvenient but it is better than crappy roads all over the state that NEVER gets snow. Portland averages 2 inches of snow a year. So clearly it makes sense to ruin the roads for all that snow!!!
Anyway, those studded tires create large grooves in the road. I have always had smallerish cars, so I’ve always driven outside of the grooves when possible. It is a quieter ride and safer when it is raining.
So the question is….do you drive inside or outside of the grooves?
