Got these on my new Fj Cruiser. Glad I did, we got a lot of snow this winter in the mountains of Montana. About 50% of my driving is back country driving on dirt roads that are many times either unplowed, icy, or slushy. I got these tires studded and they have worked very impressively. They work fine on the highway also, but a bit noisy with the studs. Great tires for the FJ!
