Slight vibration on steering wheel after installing 666m wheels

I switched out my 19" 437s to 20" 666m wheels 2 weeks ago.

666m's are great until I go over 70 MPH+ on specific parts of various roads, when the steering wheel vibrates slightly but noticeably. this never happened with the 437s.

Is it due to lower profile of the 20" tires transmitting road contours more directly to the steering wheel than the 19 inchers?

The vibration occurs occasionally whenever the car goes over 70+ mph.

Any input would be much appreciated

No, maybe one wheel isn’t properly balance? Slight bent?
I never had any issues UNLESS is super cold cold out that’s when I feel the car isn’t as smooth but I guess once the tires warm up is all good. Recheck your balance is what I would suggest bc you shouldn’t have any vibration if there aren’t any road surfaces issues.

Steps are similar to installing spacers. Have the wheels checked on a balancer to verify a weight didn't call off or the wheel isn't bent.



- Remove wheel and clean hub of all dirt and/or surface rush with a wire wheel to ensure a clean and flush mounting surface, eliminating any chance of vibration.
- Reinstall wheel lugs and torque to 103ft lbs by hand in a star-like pattern with tire on ground.

Nothing to do with tire or wheel size.

It's either a bent wheel, not balanced right or uneven tire wear. Wheels new or used?

I bought them used and put on new tires and didnt see any damages on the wheel. Front tires had plenty tread left so i got new rear tires only. could this be the problem? should i have gotten new tires for the front as well?

I would have your fronts rebalanced first, cheapest option. Then see if this fixes the shakes.

Tires can have flat spots from sitting with the cars weight on them, my trucks experience this because they sit for a month or more, after driving for a while they smooth out.

I would remove the wheels, run a wire brush against the hub then re-mount all 4 wheels: using star pattern and torque to factory spec of 103 lb/ft. If vibration continues then your front wheels are either out of balance or bent. If the vibration is substantial then it's not a balance issue, wheels are bent.

Since you didn't replace the rear tires, your shop had no reasons to check the front balance.

I balanced the wheels and it seemed have resolve to issue

Side story, I got it done at a local tire shop and the idiot technician rotated the wheels front to back, back to front. I didnt realize this until I was trying to drive off but the tires weren't budging in the front and rubbing against the wheel well. I got out and saw the 285 rears mounted in the front and 265s in the rear, UNBELIEVABLE. You could tell the tires are staggered from a mile away..COME ON MAN!

He put the rears on the front!?! You really have to do almost everything in this world yourself.

How the F do some people even survive?
