2000 miles ago I got a set of 285/75 MT/R's mounted on Outlaw II wheels put on the truck.
for 2000 miles, the ride was perfect. Balance was perfect and tracking was dead on straight.

Last week I got a balance and rotation doen.
Right off the bat I noticed the truck pulling to the left, and if I hit the brakes and let go of the wheel the truck almost did a U turn to the left.

So Discount ordered me two brand new tires for the front. I had them mounted on today. Now the problem is a wobbly steering wheel. Somewhere between 40 and 55 the steering wheel shimmies left to right in a very annoying way.
The truck does track dead on straight once again.

So I took it back and they did the following, all on the front tires.
Roadforce test, came out excellent.
tested the wheels and they're perfectly round.
Balanced them using the haweka and without using the haweka.
Pressure is set at 35.
Still the wheel shakes.

I was gonna rotate the tires back to where they used to be, but I wanted to see what you guys think first...

Any ideas?

Cheers,
Ziad
