08 Silverado Aftermarket Wheel & Tire Problem

I have a 2008 Silverado that I have installed 22" Wheels and tires (22x9.5 with 305/40-22 tires). Prior to the install I had none of the problems that I am going to talk about. After installing the wheels & Tires I had a couple different vibrations going on. The first I figured was a wheel balnace problem and after having the wheels and tires Re Balanced the first has gone away. The second vibration occured whenever I step on the brakes. I get a pretty severe vibration which seems to be coming from the rear of the truck. This seems not to happen everytime the brakes are applied. I am so happy with the way the truck looks with the 22"s but I can not live with this vibration (yeah I know DON'T use the brakes). Could this be an issues with the ABS?? HELP Please!!!!!:runaround:

pulsations and wheel slip may be your problem...reduce the tire pressures in the rear tires by 15% and see if it improves...

the low profile tires are stiff....like to bounce..
