Ken, keep in mind that if the new rims are not specifically designed for the TPMS sensors,
you'll likely need a bit of weight opposite them when doing the balancing. I believe that the stock GM wheels for use with the sensors had taken this extra weight
into account when the wheels were made.

And by the way, I've dealt with GMPartsHouse on a number of occasions and was pleased
with them every time.
