$25.00/$35.00!??!? Good grief... I'll stay in NE! I get mine (Dodge Power Wagons) done locally here at the Farmers COOP (cage and all safety equipment) for about $7.00 dismount and $7.00 to mount. Truck stops around here do it too, but they're always so busy I take mine to a small town COOP.

As Mr. Foster asks - are they split-rings or are they more like a lock-ring with split rims? All are old school and can be dangerous, so check with the local truck stops that offer those services to the BIG guys.
