For winter I would want more traction. Your theory of thinner is better for winter ( except to avoid snow packing in wheel wells) seems a bit off to me but your car your choices.
It's not a theory, it's conventional wisdom and common sense. Narrower tires have a smaller contact patch. Same weight over fewer square inches gets more PSI on the ground. A wider contact patch is less PSI to cut through deep snow.
Some basic googling shows that if your summer tire size is 205 or wider, you will benefit from a narrower winter tire.
Its not.. trust me. I ran 205/55/R16 one year.. absolute garbage in snow.
Last couple of years I ran 185/65/R15.. talk about MAJOR difference.
I can drive with confidence and dig in (even in snow over 1ft +). Before.. I would get stuck in snow about 2 inches deep. Totally useless running larger width tires in snow. In fact, its downright dangerous.
I've run the stock 195/55/16 Winter tires with similar foot-of-snow abilities. Nothing quite like leaving undercarriage marks behind you. I wouldn't want to go any wider, but also don't see a 15" wheel though.
I have also never driven a car into a telephone pole.
Agree to disagree, but you don't need to be a dick about it.
I run the 15'' tires cause they are cheap!! Haha! That and they don't make a 185/55/16 that I know of.
But mostly just because I'm cheap and the tires are nice and narrow for winter.
I'm glad there is some science behind it. I have always just heard that narrow tires are better in snow, and until I tried it didn't know. Now that I run them, I will never go back to wide tires in winter.
At around $65/tire new.. can't go wrong!!
Well, until you want bigger brake calipers that is. Haha.
Also, I only ever ran into a telephone pole cause I passed out due to low blood sugar. Not by choice, not by crazy driving. **** happens.. not my choice though. Actually have it on video too. Didn't even slow down or hit the brakes at all.
Probably why I walked away with no injury too was because I was just out. Woke up to the sound of my front end crunching.
A guy near me did the same thing a week after in a larger car and died. Guess I am lucky I only got the Honda symbol burned on my arm as a reminder that life is cheap on this planet an we are but a grain of sand on the beach.
