I had them studded,thus the noise level was a bit high. Great tire overall. Have no problems with traction now for the winter driving. With the Summer only tires I had to move my car in the lot for plowing and got stuck every few feet. Not made for snow, but now I feel safer and more sure of not getting stuck or sliding off the road. Steering is not as good on the road as with the 20 rim and summer tire but as expected they are good for winter driving. Aspect ratio may be the reason for the looser feel. Stock Summer Size 255/45ZR20 Rear 245/45/ZR20 Front. Winter 235/60/18 all four corners. Down sized to 18 Wheel. They are studded so I don't push them real hard, don't want to rip up the roads.Over all great for Winter driving. This is a 6 Speed manual with 392 Rear gears. So Easy off the line, or spin the wheels, rip the pavement or pull the studs out of the tires.
