Steering Vibration at high speed

[Saif]

Hello,

i have a problem with my QX70 2015 model.

i have recently changed the tires and bought Goodyear tires, i had a vibration on the steering at 120km/h speed, the supplier did the balance 2 times but the vibration did not disappear, we ended up changing the tires to another brand and i have used Dunlop now but the vibration is still there.

i asked in different placed but everyone was suggesting that it is a tire balance issue.

has anyone faced such problem? what could be the solution?!

many thanks.

If it wasn't there before the new tires then I suggest road force balancing.

How many miles on your car?

it don't matter even if the wheel are well balanced a bad wheel alignment will cause lots of vibration at 100 k or more

If you can running aftermarket rims, the hub-centric rings maybe worn or placed back improperly?

Did you ever chase down your vibrations?

Just a FYI, the CDC sport shocks are constantly adjusting and if there is any slop in the suspension it acts weird and drives harsh. It also takes 10-12 drive cycles for the cdc adaptive logic to relearn the new parts. OE sway bar end links and Urethane sway bar bushings fixed 90% of my vibrations high speed. The steering rack also has wear about 100-120k miles. If you are not getting a road forced balanced tire, your tires are not balanced. Firestone has just put new machines in all of their locations August 25. They have a match balance option you must ask for it’s extra money. It’s an added step clocking the rim and tire to optimize the assembly.
