Run Flat Tires
I have "run-flat" tires on my car, which is an all wheel drive vehicle. It has a computer chip in it which senses the road conditions and, if necessary, automatically activates the all wheel drive. I don't know how all this works. From what I understand, if I am driving and there is a sudden snow, the AWD activates and theoretically, even though they are not snow tires, I should get better traction with AWD. I also have some kind of traction button I can press if I am going up a snowy hill and need extra traction. Not sure how this works either, but I have used this button a few times.
I recently paid about $880 to have 4 new Continental AWD "run flats" installed. I happen to have a tire shop near my office and the owner had recommended these tires. I previously had Bridgestones, and the Bridgestones wore out after 30,000 miles which was very disappointing, to say the least. A lot of those 30,000 miles were spent driving on those Bridgestones to Montreal!!!!!!!! My tire guy said the Continental run flat AWD tire should wear better, yet it's cheaper than the Bridgestone. Also read good things online about the Continental tire that backed up my tire guy's statements.
