Pressure tank issue??

I have a well rite(flexcon) 62 gallon tank-its about 15 years old. I'm using a 40/60 pressure ratio on my Square D pressure switch. The tanks is set at 38#s and is slowly losing pressure. My pump is a submersible Goulds pump(110 feet) with a Grundfos controller
I filled it to 38# two weeks ago and now its at 31#s-this has been slowly getting worse. Making the pump short cycle and give strange high pressure readings on gauge. This is the third time in past 3 months I needed to top off air pressure.
My question is this tank bladder giving up and needing replacement???
also is there a better brand tank out there to get this time? WellXtrol?
Well

PS
I take the pressure readings with water pressure drained and have a super good pressure gauge.

Think of it like the tire on your car.

Make sure you measuring it with the water drained from the tank and a good quality pressure gauge.

If it's losing air, it's shot.

According to the experts here, the lifespan of a new pressure tank is about 8 years.

I'd say that tank doesn't owe you anything. Probably won't get that from any new one, regardless of brand. Best to limit cycling to extend the life of the system.
