Highway Speed Vibration 2024 Possible Tire Size Upgrade from 285/45R22?

[2024NAVBL]

Im not sure what happened to the original thread but going to start a new one. Many were complaining about non L versions having very notable vibration at speeds ranging from 35mph in certain spots to areas upwards of 80MPH+.

Ive been to 2 dealerships over 5 times to address the problem and have had a set of rims changed as well as 2 different complete tire swap outs- first with Pirelli.

In addition to all that ive had outside shops run high speed road force balances to no avail. At one point I made the dealer line up 5 navs for me to drive and 4 of them had the problem- the one that didnt I made them put the tire/wheel pack of that vehicle on mine. It improved the issue but did not remove it and the recent Hankook change improved it largely but the problem is still noticeable at 80MPH and having to trade up Pirelli quality with hankook sucks- the handling is diminished and road noise very noticeable. I only stick to Mich or Pirelli on my cars but will live with this for now.

FINALLY, at least, Lincoln has officially documented the problem with a system reference of "SSM53661" which calls for various tire work/swapping/RF balance/ and alignment. If you have this issue and your dealer says they don't know anything about it or cant figure it out, reference that number as it calls for certain diag approaches and ultimately a change of tires under warranty if they try giving you the run around.

That issue aside, these trucks always have bad manners over local bumps and I think the issue is the lack of amount of sidewall on the 22" factory tires. I am contemplating changing the standard 285/45/22 to 295/45/22 with Micheline. Has anyone else done so or looked into it? It seems the change would provide taller side wall, wider stance, and minimal calc difference affecting the odometer and other systems. Please let me know and ill continue to update any further developments I come across.

Hi 2024NAVBL. You are looking to increase sidewall height for a smoother ride, so here is another option:
In this particular case, switching to a 295/45 tire only offers a minimal increase in sidewall height (~3.6%). And the additional tread width will not help to obtain a smoother ride.

If you are going to spend the money for new tires in hopes of a smoother ride, and since you only need a tire with a taller sidewall…perhaps think about switching to a 285/50-22 tire size. Doing so will give you a taller sidewall without the unnecessary added tread width.

In fact, switching to a 285/50-22 tire will increase sidewall height by ~12% over the factory 285/45/22 tire size, instead of only ~3.6% with a 295/45-22 tire.

The benefit would be a taller sidewall than a 295/45-22 tire, for likely the same or even lower cost than the 295/45-18 (A guesstimate, since I did not check pricing). Even including the added cost of speedometer/odometer recalibration, which after spending that amount of money, I would do either way (see further below).

There is more than enough room in the wheel-wells for that sidewall increase. And again, without any additional, unnecessary tread width increase. And in my opinion, a 10mm tread width increase will not do much for a “wider stance” look underneath a vehicle the size of a Navigator.

Again, just another option that gives you more of what you are actually looking for.

Either way, I would also think about having the speedometer/odometer recalibrated by a competent dealership, or doing it yourself via FORScan software.

I’m sure others will also jump in to help, so keep us updated, and good luck with whatever you decide to do.

My service department blamed 'flat spots' when I complained at my first service visit.

On my next visit, I'll reference said document and try again.

Thank you for the doc reference. Should all ford dealers have road force balance machines? I asked one in my area and got the "unsure" response.

When i think road force balance, i think about spinning the tire to the rim.

Thanks good advice for another option to consider. Im going to look more into it

Yes the they said the same when I purchased new. I called this issue out on the test drive and bought the flat spot excuse. I went through hell to finally get a result. Lincoln finally ackw the problem so tell your dealer to look into service reference SSM53661
