The only way to get a 4Runner’s aftermarket tires n wheels not to shake is to do the following.

Rims must be hub centric. Either the rim must be built that way or you have to use an adapter ring. Preferably built that way. 106.1mm
(Your search results might vary ����)

Tire balancing. Most tire shops do not know how to properly balance tires for 4runners. When your tires are being setup on the balance machine, the rim must be mounted to the machine HUB and LUG centric. Just the same way it is while mounted on the 4Runner. 99.92% of tire shops just hub center the rim using a cone on back of the rim, spin balance the tire and call it a day. WRONG! It won’t work on a 4Runner.

Watch this video and you will see exactly what I’m talking about.

If you have out of round tires or tires with excessive road force you will never get the shake to go away. If the tire store you used doest have a way to balance your new tires the way the video shows, go to one that does.

GOOD LUCK

Nice video and interesting mounting system. What I see (as an Engineer) when I look at it though is a very accurate lug centric mounting system.

The other thought / comment I might have is that as far as I know, it's impossible to have hub and lug centric mounting. You either have one or the other. For instance, if you have a true hub centric wheel, the wheel center bore is centered exactly / tightly on the hub center. No matter what your lug nuts do, it's not going to move off of that location.

Your thoughts?

Depends on tolerances. If the hub has even a slight allowance of the wheel to move or if uneven pressure by the lugs can cause a minor misalignment on the hub then it throws the balance off at varying speeds.

The lug nuts are acorn type, so they will cause the wheel to move ever so slightly and is why proper torqueing technique is a must.

I agree with what you said, but if tightening the lugs indeed moves the wheel at all, then it's a lug centric system in my book. (With all of the wonderful problems that come with it.)

I haven’t had any acorn nuts on my 2014 or my 2021 T4Rs. There is a flat retained washer on my lug nuts to match the flat surface on the wheels.
These wheels are hub centric only.
They will not move on the hub, but always torquing sequence is a must!

I installed new wheels and tires on my 2020 ORP, went with RRW wheels and TOYO OC AT3 stock size tires. Within 100 miles of installation I noticed steering wheel shaking back and forth likes tires needed balanced, took back to Jack Williams Tire and they road force balanced the tires and said all is ok. Next day no better, I checked tire pressure and all right at 32 psi so I called them and they said bring vehicle back in. I then looked at sidewall of the tire and it said max load at 44 psi so I increased pressure to 38psi and took for a ride. No more steering wheel shake at all at any speed. Wonder why increasing pressure solved the problem ? Sticker in door jamb of vehicle says 32psi, the RRW wheels are 8.5" wide with zero offset and look great. Stock wheels are 7.5" wide.
