Tire chains are kind of a mystery if you are new to them . Jack it up and drape chains over top of tire , with the S hook on the inside and the actual tesioner on the outside .You want the cross chain hooks smooth side on tire . Wiggle them around and get cross chains sort of evenly spaced .Get under there and hook the inside as tight as possible . You may have extra links hanging , but that's okay .You may have to take a cross chain out also . Now wiggle things around and hook the outside as tight as possible .That outside breakover latch is the key . Geta couple bugees inside and out , you should be good to go . Idon't bother deflating because those tires are pretty stiff anyway , whatever floats your boat . Hope this helps .
