Can anyone tell me what pressure gauge they got and where they got it? I can't find anything for low pressure that has the presta valve.
TIA

I find the 30psi version to be solid for most mountain bikes. I used one for a fatbike with 26x4.0 tires quite effectively. That said, I think if you were using a fatbike with 5" tires in deep snow a lot, then the 15psi version would probably be a touch better.

Available from lots of places so you can avoid Amazon.

This question comes up frequent-ish, and the answer is pretty much always the above. The Meiser is available in 15+30PSI.

I use a 30 for 99% of my riding. A 15 is less useful for even plus bikes, since you can damage the gauge if you go past 15psi.

I had a 15 for the fatbike and 30 for others. Valve got jammed with sealant on the 15 so now use the 30 for both bikes.

Feel like the 30 is fine for both and since they eventually get ruined from sealant, I’ll probably get another 30 for redundancy.

The 15 is probably the right tool for the job for a fatty, but at the super low speeds you’d be running at 0-3psi it’s probably enough to use the grip test at that point.

This has been A great add to my shop. I don’t know how low you are looking, I run low 20s, in high 19s and it has been consistent with that pressure.

I have used the Meiser Accu-Gages (15 and 30) for the past few years and they seem to work without any issues. I decided to get the Topeak SmartGauge D2 (as linked in the post above) a few months ago to go only have one gauge and I like it a lot better. I run my pressure in the high teens/low twenties.

I keep a Meiser 0-30 on the bench in the summer, and the 15psi version replaces it for winter.

Just be careful not to drop it... the needle will bend and rub and give you false readings.

I use my hand. This is what my pump reads when my tire pressure is good:

This is what I would recommend to anyone wanting to check pressures in the range of 6-12 psi...... Use a 100 psi gauge.

Well, the problem is filing tires inside means the pressure outside will be different, due to temperature change, which with a fat-tire is pretty substantial. So I don't use gauges, I use pushing on the tires with my hand with body weight and how they react to the conditions. The latter being very critical in soft snow conditions. If I am pushing with my front wheel and unable to maintain traction, I need to let out pressure. If I'm getting bob and excessive tire-flex, as well as folding casing during turns, I need to increase the pressure. This change and does change several times during rides. Not always, but conditions are so variable on snow that it's normal-operations to have to adjust. So you can pull out a gauge every time I guess, or learn how to read what the tires are doing, because a set PSI isn't going to work. I call it PSI anxiety.

Lol... there IS a correct pressure. And a low pressure gauge is WAY closer than your "voodoo" method of sensing your pressure for the uninitiated. Not saying it does not work for you.... sounds like you have a ton of experience and know your tires. But for a novice... or just this side??? Use a low pressure gauge.

What do you consider low pressure? 5 psi? 20 psi?
A Blackburn is good down to about 10. I haven't tried it lower.

I have a fat tire bike so something to check those tires. 0-15 I suppose

I remember one occasion when I was messing with learning tire pressures for my fatbike. I found if I inflated to 2psi in my basement before the ride, that once the tires got cold, they'd read 0psi and rode how I wanted them to in those temps (I don't remember what temps, but probably somewhere around 20-25F as that was the most common temp range I rode at on my fatbike).

The great part about using a good gauge for the pressures you'll be running is that you can actually observe what's going on in a chart like this. And - gasp - you can make predictions so you don't have to mess around with a pump in the cold as much.

There's no real point in getting too deep - as I'm about to do! But if it's 70 degrees on a sunny day on Slickrock, the air in your (black) tire is going to be much warmer than 70.
This is what we used to call "picking the fly sh*t out of the pepper". Being unnecessarily precise. I'd just check at the trail head.
