I have been using Pirelli Winter Carving studded tires in OEM size on my '08 Fit Sport in a rather representative Interior Alaska winter. Glare ice, snow, dry roads, temps down to -44 F. I am really pleased with the tires, in snow traction, driveability on ice and dry roads. I got a Tire Rack package with pretty inexpensive Sport Edition wheels that were being D/C, and I am really impressed with the balancing in that I get no vibration whatsoever at any speed up to the 75 mph I've had it up to. There is increased noise but no biggie. Anyway, I highly recommend the tires, and they look nice also.

 

ditto i have them on my fit. last month i drove down my road which was a sheet of ice and wound up in the street. luckily noone was coming close by. ordered them that day and love them. funny though hasn't snowed really bad since i put them on.

But they are awesome tires.

 

I have the non studded ones on my car now. They are pretty decent in the snow.
