All depends on what you're driving in and if you have a need to go up/down slopes. When I'm backblading snow down to the pastures the lands pretty sloped and I'd be stuck without chains (and I have R1's). Got the tires loaded and that makes a huge difference but still better with chains. If I were ONLY snowblowing I could get by without chains but when using the back blade or doing loader work in the snow, the chains give me much better traction and are well worth the $200 they cost me.
