i have a slight hop/vibration at 45 to 50 mph ..ive ruled out tires due to the set of new michelin ltx 245/75/16E i just put on. it also did it previously with the worn tires. i looked for missing "wieghts" on the drive shaft and had the wheels spun without tires to see if the are true and all checks good. just wondering if y'all might have some ideas

thanx for your time
