Sure- your speedometer will read a little lower than it should (meaning you will be traveling faster than it says you are), but it won't be too far off.
tire options HMMM...this opens up even more options. This is for winter tires on that white RS clone I have coming.
Aren't winter tyres supposed to be narrower so they can cut through the snow to the road surface below ? Wider may not be better in this circumstance. Stuart.
For winter tires think the exact opposite of summer tires. Taller and narrower is the order of the day. If your RS clone has 15s I'd look for a set of 195/60/15s or so. Otherwise, get the narrowest tire you can for those 16's for winter use.
+1 to the above. The less the surface area of the contact patch, the more pressure is exerted on the contact patch. (The weight of the car divided by total surface area of the combined contact patches. The smaller the overall contact patch, the more weight is pressing down on the snow/ice.) More pressure = more heat. More heat = more grip.
It has nothing to do with heat. You are not melting the ice/snow with your tires. More pressure combined with the soft compound of winter tires (they are soft even when very cold) will allow the rubber to deform around the surface irregularities on the pavement/snow/ice giving you more grip.
