I would let perhaps 10 lbs of air out of the tire and then check the pressure.
Then I'd try again to raise the pressure. Does it return again to that 95 lb number??? or will it not allow you to raise the pressure again.
Do this and if it doesn't work let some more out and try again. You will then know if it's the compressor or the valve stem. Unless you don't have that little gate valve open on the air compressor I'm guessing it's the chuck.

You should also check the air chuck. I bought two, both had 90 lb maximum printed on them.
Bought a Heavy Duty check with no presure limit, worked fine.


+1. I've had cheap chucks refuse to work when the supply pressure was greater than about 60 psi, regardless of the tire pressure.

I would run it down to the nearest tire shop and get them to fill the tires. If they have no problem then you will know it is your compressor.

I just got back from Discount Tire and they fill all four tires with nitrogen to 75 lbs free they never charge me I know it is not 125 lbs but I am sure they will do them also.

Hi,

My 120 lb compressor can just *barely* do 85 lbs. To do that I sometimes have to deliberately let some air out of the compressor tank--then let it cycle. This gets "old" rather fast with six tires and two air bags (don't forget the spare, too). When this compressor dies I'll look for one that is 130 lbs.

You may need a higher pressure compressor.
Amazon.com has a 150psi pancake compressor w/dual gauges for a very good price.. I love mine, I think it's a Porter-Cable.

how long of an air hose? Pressure drop does occur in an air hose. If hose is long and or small diameter I'd bet you don't have the pressure you think at the end of the hose

I think this is incorrect. The volume may decrease, but not the pressure.

I actually does decrease with length of hose. When I used to do custom painting, I had to compensate pressure at the regulator based on hose length plus I had a guage I put on at the end of the hose to check before hooking up the gun . Here's a sample chart of pressure drop

Not pertinent to the thread, but an interesting and funny story:

My wife called the other day from a gas station where she was putting air in one of her car's tires. Said she couldn't put enough in and was having trouble holding the chuck on. When I asked her what the sticker on the door jamb said the pressure should be, she said "220." Since I'm the engineer in the family, I had to explain that that number is the pressure in kilopascals (metric). It's equal to 32 psig.
