Riddle me this:

In the morning when I start driving by 2018 runner, I have a front end vibration and I can feel it in my steering wheel at around 60mph and after a few miles it disappears. I have 37psi in my tires and I have toyed around with different pressures and have the same results. Seems like whatever it is, after it warms up its gone. Anyone else experiencing this? Just cant figure out what needs to warm up for the vibration to disappear. Thanks in advance.

IMHO: Rotate back tires to front and see if it goes away.

My '19 TRD ORP does it occasionally. I think it's just the tires flat spotting from sitting overnight. Once it is driven and the tires warm up the flat spot goes away.

Your tires flat spot when sitting. The 4runner steering is sensitive enough for it to be obvious. Jack up a front wheel just barely off the ground by a couple of millimeters, put a flashlight on the ground facing out from just inside the tire, look from the outside of the tire and spin it. The flat spot will be immediately very obvious and is the cause of the cold tire imbalance.

Tires are cold and “flat spotting” from being parked? Probably more prone if parked on concrete or cool flat surface.

I only drive my 4Runner on weekends, so the vibrations happen everytime. As others have said it is due to the tires flat spotting after sitting around for awhile. 2-3 miles on the freeway and the ride become smooth as butter again.

Fyi - if you have a limited, dont try this.

Are you always driving on the same stretch of road when it happens? I have a short stretch of highway that has some irregularities in it that causes that on my 2019 ORP. it doesn't do it anywhere else.

I agree, the cold temperature and flat spots are causing the vibration. My Falken wildpeak at3w load C seems to do this more than the factory Bridgestone Dueler.
