Spare Tire Air Pressure ?

[RobbS]

What is a spare Tire Air pressure supposed to be? Thanks

Regarding on-road tires ...
Full size spares are generally the same as the others on the vehicle.
Mini-spares typically are 50psi or so.

All tires have their max inflation printed on them somewhere; can you not find the rating?

Most temp spare “donuts” are 60psi. But like the above poster pointed out, the pressure should be noted on the sidewall.

If yours is like the one shown in this e-bay posting, there should be huge letters and numbers on the sidewall to provide that information...

Give details in posts. It helps.

If your 2001 LS is like my 2003 Grand Marquis, it may have a full-size spare, which would be the same as your other tires, 32-35 PSI. Or the temporary would be 50-60. Definitely check the sidewall… And thanks for the reminder to check the pressure on mine.

My car ain't got no stinkin' spare tire.

Usually the donut spare itself will have it listed ...
I try to go for 10PSI above that. They will always lose a bit of air before they are needed.

I check the spare every oil change - and inflate it with dry air to the maximum sidewall pressure since it will sit for a while.

I know I am within tire limits at that pressure. For a temporary, you need to be close to that pressure for the load rating to be valid. And for a full-size, I will air it down to recommended if I have to put it on.

Just checked the '12 Camry and '21 Corolla which both state 60psi as mentioned above. A.P. is noted on the driver's door jam also in most instances. I've been meaning to air them so will do so asap.

It doesn't say anywhere on your spare? that's odd.

The spare-tire pressure is typically listed on the sticker on the driver's door jamb.

If the spare is full-size, the pressure will be the same as the other tires.

If it's a space-saver ("donut"), 60 PSI is typical for a passenger car/minivan/crossover.

Thank you all..
I will check the sidewall today. I will fill it up to designed pressure.
I wanted to make sure the labeled pressure wasn't a "max" pressure and actually a road ready pressure. If that makes sense. Thank you all for the help!

I normally put my spare tires at about 5-6 psi higher than what it says so I don't need to get it for the next 6 months.

I say max pressure on the tire. Then release any extra pressure when you use it, if there's any excess by the time you need it.

If it's a donut, usually 60 psi. If it's a full-size spare, the same pressure as the other tires.

Also, if you have a donut, consider replacing it with a full-size spare. Get a wheel from the junkyard and a used tire (or a cheap Douglas from Walmart)

As an update, and thanks to all the people reached out to help thank you.
So I Did find a spare Tire and tools. Pressure was 27. Tire pressure was very, very low to being dangerous up front especially.
I bet it is very common to not check Tire pressure.
Anyway, my wheel is at 60 and I got an eye on it.
Be Safe!

I just checked all 3 spares on my cars yesterday added air to all.

I inflate the spare in the wife's Honda to the max ,as listed on the sidewall: 60psi. If it ever gets used the pressure can be reduced.
