I use my hand pump and get my tire to 110.
Then to double check I use my digital hand gauge.

The only problem is every time I use the gauge I lose pressure and have to throw some more air into the tire.
So.... is there really any purpose for the hand gauge.

It will help if you use a pump with no gauge.

don't double check?

I was under the impression that Presta valves close up as soon as a change in pressure occurs (i.e. when gauge or pump is removed). The only air lost is in the hose or outside the valve.

If you gauge is losing that much air, you should get another gauge. It might be helpful to not unscrew the nut on the Presta valve that keeps the valve closed as much so that it will only open the valve less and only when the gauge is very close to seating on the valve.

So get a floor pump with a gauge.

There are still floor pumps without gauges? I genuinely cannot remember the last time I saw one.

Then the OP will have to add air a third time.

A follow-up would be what's your favorite gauge for the road after a flat?

A hand pump is for roadside emergencies and not regular use. Get a floor pump.

You will lose air using a gauge. It can't be helped. But the more you use it, the better you get in avoiding loss.

My lezyne emergency pump HAS a gauge as well

Is this a thing? Seriously?

Can you actually tell/feel the difference between 110 and 112 psi? (And assuming either gauge is accurate?) And for the fraction the gauge is inserted and released, how much pressure do you think is lost?

Unless of course you're Tom Brady and can't tell the difference regardless.

Floor pump with gauge obviates the issue. The pressure on the gauge is the pressure in the tire at the end of the pumping process.

Road Morph G also has a gauge.

Pump it up to 110 or whatever and give it one squirt of air. Very simple. I'd like to know what hand pump the OP uses to get it to 110.

Who uses just a hand pump? Go get a floor pump with built in gauge. Problem solved, and life is a lot easier

I set the outlet pressure on my compressor to 100, and hammer the air in til it stops.

Obviousy a 400 watt compressor.

ikr? No pump I have ever owned. But then I've never had Lezyne.

Correct...no need at all... Squeeze the side of the tire, if it feels too soft, add air.

Also, I got by with just a frame pump for several years. It had a gauge, and got me up to over 90psi, which is plenty for 25mm tires and my 160 lb. Body. Never felt a need to go harder, and in fact never maxed out the pumps pressure.

Got a floor pump last Xmas....it's just faster is all...and I can use it on cars in an emergency.

Funny part is my floor pump with gauge cost less than either one of my frame pumps.
I could get my tires close without it, but it's nice to know that I inflate them to the exact same pressure each time before I go out.

I use the tire gauge in between pumping days, to see if I need to use the pump. If the tire gauge says 100, I know I'm good to go without getting the floor pump going.

My Lezyne micro floor pump HPG can get up to 160 psi. On several occasions I have pumped up a flat for a club member to 110-120 with not much effort.

It's not Nascar it isn't that critical. Get it close and don't sweat it.

You can get mini pumps to more. Usually it requires a rest break at 90 lbs with an on road nap, some sports drink and energy bars, maybe a few breathes of O2, and a massage.

I'm 185-190lbs and I run 25mm tires at 82ish psi. You might want to experiment with lower pressures --smoother ride. Smoother = faster.
