I have 19. 5's (Rickson's) on my truck; They're great. No effect on the braking or parts. What new brake kit? (I did add the 1-ton wheel cylinders to my 2500 and that helped). Nope, the ride isn't "bouncy". I have almost 40,000 miles on the tires and there is more tread left than on the OEM's when new. They did drop my RPM's by 150 at 70MPH.
