I have been debating trying this for some time now, after I put the 19. 5s on I have had a vibration that starts at about 63 and got worse the faster I went. I had the tires balanced but it did not fix the problem. The truck was never not drivable just annoying I knocked the wheel weights off (a couple had fallen off on there own) added 6oz of equal to each tire I have now put about 250 miles on and it is a lot better not like the wifes sedan deville but much better. It seems like they come out of balance on big sharp bumps but only for a second or so then they smooth right out again.
I am very happy with the results.
