Ok iv got an 07 4x4 with 111k on it. I just went to 20 inch wheels and 35s been running them for a month or so and now all of a sudden its got a pretty good vibration between 60 and 70 sometimes you can feel it at slower speeds. Iv done everything i can think of to try and find the cause rebalanced tires twice been on the alighnment rack twice checked all suspension parts jacked up and with weight on the truck!! its killin me please help!! thnaks!!!

 

Can you feel it in the wheel?

 

pull one of the wheels off and make sure they took the caliber locks off they just press on the stud and all you do is cut them off when i worked ad discount tire and we put after market rims on anything those have to come off or you get a vibration hope this helps you

 

Have the tires rebalanced!

 

All the u joints check out?

 

When you balanced the tires did you ask for a road test?

I've heard of a tires balancing fine but failing the road test because the tires are bad internally, giving you the problems you're talking about.

X2 Rear drive shaft U joints? Also a carrier bearing if you have a two piece drive shaft would cause a vibration...

 

u joints carrier bearing

 

carrier bearing or u joints will do this

 

I have the same problem on my 06. Just put brand new procomps on all the way around on the stock rims. Took it to a different shop to have them balance it and the tires are actually out of round. All four balanced out perfect, but the guy brought me in and showed me how out of round they were on the balancing machine. I ran the exact same tire for 68K (rotating every 5K) without a hitch. Rode like a caddy, now it beats the hell out of me between 65-72. Guy said he's seen it before, usually wears round by the first rotation... I'm on week two 60 mile round trip commute per day... If you have them put it on the balancer you can actually see the rim hold perfectly straight and the wheel bob up and down...
