How do they do they change the tires?

I just had mine replaced about a week ago at Discount Tire. I was concerned as well....I had Goodyear Endurance's put on and had done a little research prior.
They put 4 jacks on all 4 wheels at the U-joints and lifted, only need 2-3 inches. I pulled around to the back in the drive in front of one of the overhead doors. Stood there and watched and they really seemed to know what they were doing. They explained and showed the mfg. date on the old tires (that came on the trailer) which was 2012, so they were due. Hitched up the whole time, no big deal.
