Messed with it first time in 11 years. Guess what, the pressure is pathetic at 14 psi. haha.

That is one thing I check each season when I swap out summers / winters / summers since I have the air hose out might as well, cuz you never know when it will be needed.

It is nice that you have an air compressor. I do not have space in my garage, so I bought a super duty DeWalt 20V impact wrench to eliminate the need for a real air compressor. But it is pretty hard to inflate that spare tire. In the end, I got blisters in my hand. Maybe I should buy a light duty compact air compressor. By the way, can you set up a psi value and your compressor will stop exactly at that value?

I switched out my spare for a full size on my MDX. I usually pump the full size spare up to 38-40 psi because I will usually drop a few psi every month. I can always let air out if the psi are too high when I need the spare.

I did the Viair 90p portable air compressor I use for my bikes (700X40c and 26X4 fat tires) and pumping up vehicle tires. It was about $75 on Amazon and it connect directly to my battery for power (worry about blowing a fuse with the air compressors that connect to the 12v plugs inside the MDX). The Viair guage is off; but, I use a hand held gauge and/or TPMS to double-check pressure.

Side Note: Tire manufacturers talk about tires only having around a 10 year life max even if the tread is still good. I still have my donut spares in my 06 TSX and 08 RDX (full size spares for both in the garage).

My compressor will not stop if the PSI was set to say 35, it will continue to push air.

I have use a pro grade tire gauge, same used in tire shops and check the PSI continuously.

similar to the following.
