I did a nice 30 sec burnout to finish off my old tires 3rd gear at about 3500 rpms....the truck shook when i brought it to have the new tires installed they balanced them and i got an alignment and the truck still shakes...the rear seems to shake alot...i am taking it back to get the tires re balanced because they used sticky weights and they only put 2 of them on each side when my front tires have like 12 plus...any ideas and air pressure was correct
