Is everyone forgetting that a "mud & snow" tire is a fallacy? These 2 things require very differant tire properties.

A mud tire needs to empty itself to keep the lugs digging in.

A snow tire needs to pack itself full, because nothing sticks to snow...except... well... snow.

Chains... really only good for snow with a frozen base layer or a thin ice top sheet. A good snow tire, along with your 4WD should be sufficient, unless it's so deep you're pushing it with the bumper. In that case you're a dumbass for being out all together.

BTW... I didn't ALWAYS live in Texas...lol

Jeff!
