Question...What is the tire pressure for 20 inch tires?

Hi NavigatorPro. Assuming you are asking about the factory supplied size 20” tires: I don’t have the information available at the moment.

However, if no one else here can offer a reliably accurate reply, I would recommend calling Lincoln Concierge, where I would hope they will be able to supply the correct information.

If that does not get you an answer, go to your local Lincoln Dealership, find a model on the lot with 20” wheels, and check the drivers door sill placard to find the recommended pressures.

Or hopefully another member will jump in with the correct information, so keep us updated and good luck.

Question...What is the tire pressure for 20 inch tires?

My 18 expy had 20s and the rec pressure was 38, but i would run it at 34-36 for a smoother ride.

I run mine (aftermarket 20" wheels) at 33-35 psi. I would run a higher pressure if towing.

Look at the sidewall of the tire…

Look at the sidewall of the tire…

The PSI listed on the sidewall of the tire is the maximum safe tire inflation pressure for the tire.

It is not a recommended tire inflation pressure.

Exceeding the maximum safe tire inflation pressure listed on the sidewall of the tire could result in catastrophic failure of the structure of the tire with severe consequences to safety.

Right. The OP’s question was rather nebulous. I never advocated for exceeding any limitations.

Basically Im looking for someone with a Navigator that came with 20 inch wheels/tires. They had these in earlier models of the livery edition and the select. If they can check the tire pressure sticker on the drivers door frame near the VIN sticker and let me know.

I know someone with an F150 who says his says 36 psi.

I found the answer. It will be 36 psi. I used this website to confirm it. 2025 Ford Expedition Tire Pressure

For the 2025 Ford Expedition Max with 275/60R20 its 36 psi.

The backstory is I now have 20,000 miles on my 2025 Lincoln Navigator and the ride is getting rougher as the 22 inch tires are wearing down. 22 inch tires in general have always been an issue on whatever car they are installed on. In the past when my 22s wore down to a certain point they tended to hit nails a bit more and became a risk. I am in the limousine/livery/for hire business btw.

I have decided to switch to 20s...275/60R22 (the vehicle came stock with 275/50R22. So with the decreased tire pressure and 1 more inch of sidewall to bend/flex it should be a better experience.

The 24 inch wheels/tires on the test vehicle Consumer Reports drove...they said the ride was horrible and I can imagine. 24 inch is simply too much wheel to put on a vehicle.

My 2025 is indeed sporty and peppy with the 22s, but Im looking for a softer/smoother ride. It was soft/smooth when I got it but as the tires wore down I now have more road feel.

The Michelin Primacy LTX are better than other tires Ford/Lincoln used in the past, but they are the cheaper of the Michelin line and they dont last.

Oh wow, thats not good for a brand new car with not many miles. Have you thought about just putting newer better tires on it?

Its NOT the vehicle that is having the problem, its the 22 inch tires. These 22 inch tire problems exist on all vehicles that have them and cant be engineered out by the manufacturer. 22 inch tires simply dont last, they dont stand up to things like nails and have a rough ride. The only good thing about them is they have sporty handling for those who desire that kind of handling. So lets say you got the Escalade you will still have the same issues with their 22 inch tires.

The tires which come on this truck is Michelin Primacy LTX. Michelin is the best maker of tires. They do have the Michelin Defender LTX which will probably make the tires last to around 40k to 50k but they will not entirely solve the issues of the 22 inch tire.

On the Tirepressure website you can see the 275/50R22 tire requires 39 psi to hold the same weight as the 275/60R20 at 36 psi. The more tire pressure the harsher the ride and the more work the tire has to do because it cant bend/flex as easily. 20 inch tires are not a total solution, but will be more practical versus the 22s.

The Ford Police Explorer comes with 18s and the off-road Ford F150 Raptor has 17s...so does the Jeep Wrangler. Thats because at 17 and 18 inches it becomes a really tough heavy duty tire. Every inch you move up from that becomes less so and at 22 inches the tire/wheels look good...drive sporty on the road...but everything else becomes a problem especially as the tire wears down.

So...not a Navigator problem...but a tire problem and it doesnt matter what car you buy with 22s...they will have these same issues.

My challenge is to use what is a luxury truck built for those who can afford the trappings of a $100k+ price and use it like its a Ford SuperDuty.

... The only good thing about them is they have sporty handling for those who desire that kind of handling. ...

I alternate between the stock 22" rims and 20" rims, same Pirelli Scorpion AS Plus 3 tires, so it's an apples-to apples comparison. There is no noticeable difference between the two in terms of handling, and I don't drive like a grandma. The rim size is not the limiting factor when it comes to handling for these trucks. These 22" and 24" rims serve no practical purpose.

There are reports of these particular tires giving harsher ride than some alternatives.

As for Michelin tires being the best, a few years back I had to use the Michelin's satisfaction guarantee and return Michelin Primacy A/S because they were developing flat spots, which made the ride unbearable. Switched to Pirelli Scorpion AS Plus 3, and sticking with them. So not all Michelin tires are equally good.

The PSI listed on the sidewall of the tire is the maximum safe tire inflation pressure for the tire.

It is not a recommended tire inflation pressure.

Exceeding the maximum safe tire inflation pressure listed on the sidewall of the tire could result in catastrophic failure of the structure of the tire with severe consequences to safety.

I will disagree.

Tires are tested to two or three times the max inflation pressure so that very thing does not happen. "Catastrophic failure"
So why is there a max inflation pressure?
That is because of the load limit that the tire will handle. You can inflate to a pressure higher than max, however the tire is not designed to handle greater loads with that greater tire pressure.

As to limits
The tire manufacturer has no idea of the application for it's products. They will design a tire for a suggested application. However the vehicle manufacturer or vehicle owner will ultimately make the decision on application.
Because of Federal law, there is a tire decal or placard affixed to a new vehicle. That placard lists the minimum ""recommended" tire pressure. This is based on the vehicle manufacture's tests and designs. One can inflate to a higher pressure with no adverse issues. (To a point) Going below that pressure and tires will overheat because they are overloaded. And if continued an adverse tire event will occur that will shorten the tire life.
