RVZONE Mini Digital Tire Pressure Gauge 3-99PSI 4 Settings Tire Gauge for Tire Pressure with Backlit LCD for for RV Car Truck Bicycle, Easy and Accurate Reading(Black)

The RVZONE Mini Digital Tire Pressure Gauge is a surprisingly powerful little tool. It’s small enough to fit in your pocket, but don’t let the size fool you—it’s accurate, easy to read, and works great across a wide range of vehicles including cars, trucks, RVs, motorcycles, and bicycles1. The digital LCD display is bright and easy to read, even in low light. I really like the 4-unit settings (PSI, BAR, KPA, and KG/CM²), which makes it versatile for different users and regions. The 3–99 PSI range covers everything I need, from bike tires to heavy-duty truck tires. Using it is simple: just press it onto the valve, and it gives you a quick, accurate reading. No need to reset or calibrate—it auto-resets and shuts off after 30 seconds to save battery life. It even comes with batteries pre-installed, so it’s ready to go out of the box. If you’re looking for a reliable, affordable, and ultra-portable tire pressure gauge, this one is a great pick. It’s especially handy for road trips or keeping in your glove box for quick checks.

So I've been to a lot of tire pressure gauges throughout my motorcycle riding life and I think this is probably the best one I've ever found. It really fits in perfectly in the tight spaces, very easy to use and to read!

As a motorcyclist, I'm always looking for things that are lightweight, small, and work. Tire pressure gauges appear to be one thing that manufacturers think bigger-is-better... well, it's not. What motorcyclist wants to carry around a half kilogram (1 lbs) gauge with a half meter (2 foot) long hose?!? None of the normal pencil stick type gauges fit between the valve stem and the chain sprocket or brake rotor. This wonderful little gauge fits in the wheels and spokes just fine! It also remembers the reading so you don't have to wedge your eyeballs between the seat, engine, and the fender. I found the readings to match many other gauges I have for my other cars. The numbers on the little screen are easy to read, but the mode (kPa, PSI, etc.) indicators are small and can get lost in the glare. This isn't actually a problem unless you turn it on twice which changes the mode (oops). Useful hint: The gauge will show 0.0 in PSI mode, and 0 in kPa mode; the other two modes show 0.00. I like this gauge so much that I purchased two more and gave them to my gal and her daughter for their motorcycles. The gauge body appears to be durable plastic and the head is metal. The valve stem gasket is thick and can seal well even if it's not on straight. I've found that if you can put your index finger on the top of the valve stem, you can use the gauge on that tire. Just turn on the gauge, palm it with your index finger on the back of the head, and take the measurement. Quick and easy! Update a year later: I think I have bought 10 or more of these over the last year. I just buy another one with almost every Amazon order. I gave some away to family and friends. Every car, RV, and motorcycle has one.

The small size and angle of the head allow me to reach in to the center of my scooter wheel, which is pretty small. Many pressure gauges don't fit in that space. The lighted electronic readout is easy to see. I can't say yet how durable it is.

Great tool for tire fluctuation due to weather changes. Digital much better than old style. Bought a good tire inflator too. No more looking for stations with air. No more waiting in line at discount tires

I really like the tire pressure gauge because it’s not big and bulky. It fits nicely in the glove box and takes up no room at all. Only thing that might be a down side is the type of batteries and them being so small. I can the batteries dying quick with this little guy. But it’s pretty cheap, probably as much as the cost to replace the batteries. I liked it so much I bought a second one just to have a spare. It seems very accurate and reliable and easy to use. The backlight display is small but brighten enough to see well.

Why did you pick this product vs others?: I bought this to use on my motorcycle. My motorcycle has limited space to reach the tire valve. This one fits. Many others won't fit. However, this tire gauge has proven inaccurate. I have bought four of these. The first one read one psi low. The second one read two psi low. I had to put a piece of tape on the gauge and wrote the amount of error. I find that annoying. But, as long as it is consistent, I guess I can live with it. Given its inaccuracy, I think they are a bit pricey.

Works well
