Our 07 JK has 97,000 miles on it, we are on our second set of tires, and they are not yet showing much wear. We trailer when we are going long distance, make as wide as we can turns when we are 4 down. Rotate tires every 10k, & keep proper air pressure. We have never had the front end aligned, we always tow with the key in and in the run position, transfer case in neutral transmission in park and the battery disconnected. We have the Falcon II tow bar, and the light harness from Cool-tech.
OBTW our JK has a 6" lift kit, and 34" tires. tow bar is 1" higher at the jeep, than the ball on the coach.
