The Pressure is on.
Do you use an external pressure gauge for your tires? If you do, what do you use and what brand?

I only use whatever came with the pump and hope that it's accurate.

Does it really matter if you have 90psi or 92psi or 87psi?
You should experiment and find what works with your weight tires and road conditions.
A few days ago I stopped by the LBS to have fresh sealant added to my tubeless tires. the use a compressor and I told them to put 60 front and 65 rear. I rode another 30 miles and felt the entire time the tires were hard. When i got home I took some air out and pumped them with my pump to 60/65 and went for a 5 mile ride. They then felt normal.
Not sure which was the more accurate pressure, but my pump is consistent with what I normally use.

"A man with 2 watches never knows what time it is"
My interpretation... "A man with 2 pumps never knows the exact pressure"

and I suppose It doesn't matter if it is accurate or not. I figured out what works, and that is where my tires get pumped to. I have used other pumps, and they may be different than mine, but it's close enough.

I would think accurate tire pressure is important. IF the recommended tire pressure from the manufacturer is 100 psi and your pump is consistently low, you are not riding the tire like the manufacturer intended. Wouldn't the lower tire pressure effect the handling and the ride? Comments?

I like the Topeak digital
Had it 3 months, seems accurate
easy to use
Has some good features.
works presta & shrader

I have several tire pressure gauges, including the digital Topeak shown above. None are accurate. The best gauge I've found came mounted to the Joe Blow Sport 3 floor pump. Of the several floor pumps with gauges that I've had over 40 years, few have been as accurate as this latest one (JBS3). Not that accuracy matters, as folks have said above.

p.s. How did you determine "None" of the gauges were accurate? You must have some reference gauge to compare the readings to.
@Nachoman beat me to the question

I prefer a reasonable accuracy in my gauges, because I don't want to worry that my psi w/one pump needs to be different than with another pump. And can you imagine a tire pressure discussion amongst cyclists if my 100 psi were your 120p psi were someone else's 80 psi?

Meiser makes great dial gauges, guaranteed to be +/- 2%. Inexpensive, no batteries and a bleeder valve. Just a couple psi makes a difference in CX and I’ve used their 60# model for years. For road or general use, I just use a gauge on a good floor pump.

good floor pump with gauge is not that expensive, and of course the pinch/feel test

As others have said, consistency is more important than accuracy. I pump my tires to 100 psi, according to the gauge on my old Silca floor pump. It is truly 100 psi? Don't know, but it works for me - not teeth-rattlingly hard, but have never had a pinch flat. If I ever replace the pump, I'll titrate the pressure again to achieve this optimal (for me) pressure. It might not be 100 psi according to the new gauge, but the actual numerical value won't matter.

Tire manufacturers do not recommend the specific tire pressure that a rider should select. Typically, they recommend a range of pressures, and have a maximum pressure that has some margin of safety built in. The correct pressure will be a function of the tire volume, the rider weight, and the rider preference for feel. Pumping to the maximum pressure isn't what the manufacturer "intends" for the average rider.

And unless you're in the TDF, Its not going to make a huge difference for a single ride.
BTW, I like pumps that have the gauge at the top of the pump and not at the bottom. They are easier to see where the needle is.

after confirming the gauge on my pump matches my patented pencil style gauge, I no longer use the hand held gauge at home. but I do carry it on the road but rarely use it even when fixing a flat
