For whatever its worth, I just learned that itp has ceased production of all spider trac tires, believing (rightly or wrongly) that it had become redundant with the successful introduction of the very popular Mud-lite tire. Wholesale supplies of the spider tracs are quickly drying up, so if you were planning on getting some, you might want to speed up your plans. I just bought two spider tracs for the rear of my 650 (for trail riding) with Holeshot ATRs in the front. Thanks.
