Car Vibrating at 70+ miles

[silversurfer01]

Recently, got some new tires on the stock rim (06 Sequioa SR5). Less than 10,000 on new tires. Now when driving above 70 miles per hour, the entire car shakes/vibrates. The steering wheel, the front seats, the seats in the back. It's like someone is shaking the car literary. When looking back at the passenger in the rear, you can see their heads shaking.

Any ideas? Bad tires? Got the tires from Toyota dealer where we bought the car.

Look at the tires for any irregular wear.
Check the rims for a thrown balancing weight.
Check the back/inside of the rims for mud or something that could be throwing the balance off.
There is a slight chance when the tires were filled with air that enought condensation water was blown in to the tire that at high speeds it throws the balance off.
Check the tires for something being in the tread, such as tar, putty, etc, that can throw the balance off.
The drive shafts have balancing weights attached that could have come off.
The front CV shafts (4WD) on some vehicles have harmonic balance that slide along the axle. If it moved it can now be off balance.

Just a few things to look at..........

Typically these heavy Sequoia's can be hard on front tires. Especially if you have a lift in the front, and the alignment has a little too much positive camber. I would make sure you rotate your tires every 3000 miles, or when you first sense the vibration. I did the poly bushings on the sway bar, and steering rack and it still wanted to eat the front tires on the outer edge. I noticed this much more when I was running a mud tire, but it still does it with a all terrain.
