Steering vibration/shakinh/moving Left and Right

[taimurakhter]

I am getting slight vibration in my steering when I drive at 130-140 Km/h. I have 215/50 R17 Yokohama AVid V4 tires with v rated speed. My rims are BSA.
I went back to the tire dealer to recheck my tire balance.Although they rebalanced my front 2 tires,I still get the vibration sometimes in the highway at that speed.In a very smooth highway I topped 160km/h. But strangely, I didn't get any vibration on the steering.
My vibration looks like the steering move a very little to the left and the right (1mm left and then 1 mm right). The vibration does not look like the steering is shaking ups and downs or backs and forths.
Do I need a Wheel balance from the dealer? Does anyone have any suggestion.

Get the entire thing aligned and make sure whoever does that rebalances the tires.
*note* how I'm being nice and not calling you a tard for driving 99mph with bad steering.

Are they using a static balance or a dynamic balance? The difference is with static balancng you position the wheel weight in the center of the rim in one spot. Dynamic balancing puts one amount of weights on the innermost edge of the wheel and one weight on the outter edge of the wheel. Dynamic balancing is the more effective way of balancing.

Also are you using hubcentric rings? If not get some then have the tires dynamic balaced. If after doing the hubcentric rings and dynamic balancing you still have vibrations you might need to have the tires road force mounted and balanced to the rim. This is a process using a special balancer that puts pressure on the tire that is mounted to the rim. The maching can tell you where to line up the tire to the rim so that the wheel/rim are already closer to an over balance. Then after having the tire road forced mounted to the rim you will do a dynamic balance.

If none of this fixes the problems than look into other poss. problem areas like brake rotors, loose suspension, etc. An alignment usually won't fix a vibration.
