In that sticker that’s usually found in the door jam that says what PSI your tires should be at, for the spare tire one, it says that it should be at 60 PSI, right? But if you were to replace a flat with that spare one, shouldn’t the spare be at the correct PSI that the other tire was at?? (ie, for my car, the front passenger side should be at 34 PSI)
Is your spare a donut or full sized? Can you upload a picture of the sticker?
It’s a donut spare. I will take a picture of it tomorrow as I haven’t done that yet.
If you don't have the donut spare pumped up to the indicated 60 PSI before using it you won't get very far.
I have one of those donut spares for my 02 Mustang and it has that higher pressure than the regular tires. I think it's 60 PSI also but I don't remember. This should be a good time to go check mine since it has been awhile.
But if you were to replace a flat with that spare one, shouldn’t the spare be at the correct PSI that the other tire was at??
The sticker on the driver's side door jamb will give you the correct information. Also, take the time to read your owner's manual, or look it up on line, to get the answer your specific question regarding the psi in the spare.
They put that info on the sidewall for a reason, 60 psi it is. Also check how old it is, if it's over 5 years old you might want to replace it.
they put the MAXIMUM RATED PRESSURE on the sidewall. In other words, the most pressure the tire is designed to withstand before it can blow up. This is NOT the pressure you should use. Remember, tires get hot, and then the pressure rises.
That applies to a regular tire not tempie spares.
right you are. I haven't had one in a while. I use full size spares now.
Yeah, the donuts are much smaller than full-sized tires and rely on the high pressure for their load capacity. If you put one on that has insufficient pressure it will shred in short order. Since they're rarely used and will lose some over time the air pressure should be checked and topped up as needed before use.
