Can I also use this gauge for my car?

You can, but note that such gauges give their best accuracy in the middle of their range -- and car tire is usually inflated to about 30psi.

fwiw - I have multiple gauges of multiple ranges

O.P., does your bike have Shrader valves? All of mine are Presta.

As an aside, one of the old pop-up tire gauges is good enough to check my car's tires. And I don't obsess over the nearest half a psi on either bikes or cars, so whatever gauge is attached to a pump is good enough for me.

Decent gauge but if you are buying a new one, I agree that it would be better to get one in the auto specific pressure range. I don't see the point of a separate gauge for bike tires, though I admit to buying one before I figured out I would never use it. The one on the pump is accurate enough.

These days, there's little use for a gauge that goes that high or one for a Schrader valve. Yes it will work on a car, but the pressure range is too high.

I have a Schrader valve/lower PSI one in my car glove box and a Presta valve/higher PSI one for carrying on bike when I do multi-day rides.

Agree with the comment about the one in the floor pump being accurate enough - I've checked mine and it is within a few PSI of my other one, but not sure which one is actually right! A few PSI either way is in the titanium zipper category for me.

It'd support with providing the cold operating PSI, when checking for a passenger car's average tire of 32~35 PSI.
if the vehicle is equipped with a TPMS & there's a fault illuminated, the gauge may not display a low PSI as accurately as another gauge with a more wider range, specifically for automotive use.

Only time I'd consider a gauge with that high or similar of readout, is when I'm seating a bicycle's or vehicle's bead to prevent an unwanted event from occurring.

I prefer to inflate a bit over my target pressure with the floor pump and then bleed air to the pressure I want using a Meiser gauge somewhat like that. Mine is for Presta valves with a range of 0-100 psi.

My floor pump is made by Bell and works fine as a pump. It has a built in gauge that is fairly consistent (precise) but not very accurate.

If I inflate to a reading of 55 psi on the pump, it will consistently produce around 65 psi as measured by the more accurate Meiser gauge. Then I just bleed air down to whatever pressure I want to run.

I’m not so picky about 1 psi difference but more than three psi and it may be noticeable, especially since I run pressures towards the low end already.

This is a really weird version you've selected: Schrader valve with a kPa primary scale going up to 160 psi? Really? Maybe pick a different model, lol.

I like these Accu-Gage gauges, they're inexpensive, accurate, durable, easy to read and hold the pressure after you disengage them. I have one Accu-gage gauge for pressures up to 15 psi for my fatbike and one with pressures up to 30 psi for MTB. I have an SKS Airchecker that I use occasionally for higher pressures on other bikes but that thing's annoying to use so I typically just use the digital gauge on my pump.

This would be excellent for the higher pressure tires typical on over-the-road trucks. They typically run cold inflation pressures around 105-115 psi.

Also can be used with a Presta to Schrader adapter for those running high pressures on road tires with Presta valves. Back in my teens, I did long road rides on tubular tires and would carry one of these in my patch kit amd stop off at a service station where you top off the tires to whatever pressure you wanted. Way back then you could do that for free.
