Tacoma Wheel Shake

Hey guys,

This is my first post here and i’m hoping someone can help me out!

I bought a 2012 AC Off-road a few months and am loving it so far. I just upgraded the wheels/tires to brand new 4Runner TRD Pro’s on BFG KO2’s in 265/70/17 on stock suspension but have been having some pretty significant shaking in the wheel since then when I get to highway speed. The owner told me KO2’s are hard to balance but I’ve taken it back to the tire shop for a re-balance and if anything it’s made the shaking worse.

The truck has 89,000kms on it and I’ve put on less than 500kms on the new tires.

Any suggestions on how to fix this other than to try rebalancing again?

Thanks in advance.

 

Did they road force balance the tires and wheels? And make sure they use the correct wheel adapter.

 

I was able to cure my tire shake by adjusting the tire air pressure. I'm running 36psi now.

 

Road force balance

I'm running tire beads (4 oz each) and I like them, though some folks don't.

Check your carrier bearing and u joints on the drive shaft.

Check steering column.

Check wheel bearings and tighten lugs using a torque wrench.

If your rotors or drums are super bad (out of round or varied thickness) it can cause bad vibes.

 

Check the driver's side CV for excessive play where it goes into the front differential, then search here for ECGS bushing.

 

1. Was there any vibration prior to the tire/wheel change? If not start with the road force balance. Yes always check component tightness but your entire suspension didn’t magically go bad when you upgraded the tire/wheel package.

 

Just throwing this out there among other things above you can check and make sure wheel(s) aren’t bent

 

Are the tires load range E if so they may always be a problem at higher speeds as very stiff sidewalls and as others said lower pressures help and a must is the road force balance on new tires as it locates the heaviest spots on the tire and tells the installer where to rotate it on the lightest part of the rim in effect to help offset weight. As many as 10% of new tires are basically defective and if the shop has lots of weights on one it may be junk. So per Tirerack site the standard is 1% of the total tire and wheel weight for balance weights. So if say 90 lbs then 1% = 0.9 lbs or 14.4 ozs which is a ton of weights.

Again, check pressure and adjust and then get them road force balanced. Not all shops have the machine. Discount Tire all have them. Then switch rears to front and test drive again.
