What? They schedule mounting and balancing? Never heard of such a thing. Get a refund and get them mounted somewhere else! The important thing is to get them on the Jeep ASAP and start enjoying them!
That's the other thing; I am kind of packing the house while here, 'cause my family is moving to Panama on the 17th (they will catch up with me in Costa Rica in a couple of months), so my wife does not even want to hear the word Jeep... I'l bet she will be a little surprised (aka PI$$ED) when she sees the Jeep again with 33" with 33" tires, Warn flares, and rockers...
