Balancing and Calibrating new rims and tires?
Hey all, I am planning on getting new rims and tires put on. The rims are already here, just waiting on the tires. The place I am dealing with said they can install and balance and all the other stuff needed. (which is?) Now I am wondering, is this a hard process, can i do it myself with the proper tools? And with the calibrating, how does it work? A buddy of mine told me it would take about 10, 000kms for the computer to recalibrate it self, true?
Thanks in advance!

here's what I think I know:
Computer has to be reprogrammed with Starscan tool at dealer with new tire diameter in order for speedometer to be correct.
Balancing tires requires a balancing machine that the tire mounts onto and then they spin it up to 70 MPH, machine detects imbalance and tells them where to apply weights to the wheel to bring the wheel/tire into balance. Mounting a tire requires a different machine to get the tire onto the rim, there may be a human in the world strong enough to stretch the tire by hand onto the wheel, but that 1 guy probably isn't you.
Wheels almost never come with valve stems, and are thus provided for either during the purchase of the wheels, or installed when the tire is mounted and balanced, and paid for at that time. Generally, I've found you can get nicer stems when ordering the wheels, but this isn't always the case. The valve stems bring up another issue, the TIPM or tire pressure monitoring system. These sensors are mounted in each stock wheel if you have it (mandatory for all '08 and up models). Not all or even many aftermarket wheels can be adapted for the TIPM sensors, and the Jeeps computer doesn't like it when they're gone and manifests itself as a small annoying light on the dash panel.
