Best tyre pressure gauge

Wednesday, July 24, 2019
I once saw the mighty and magical David Bowie play. Near the end of a great show, he pulled out the song he did with Queen, Under Pressure. It was simply magic as it was pouring with rain which quite matched the lyrics of the song.

And you know what else works well under pressure? Tyre pressure gauges.

If you drive your car with under pressured tyres you'll suffer performance issues such as longer stopping distances, put more heat stress on the tyre itself, use more gas & petrol and increase the chance of having a road accident.

So if you want to check that your tyres are properly pressured, then you'll need the best gauge to take the measurement. These units are really handy if your car has a 'low car tyre pressure indicator'. If you cannot determine which tyre is low by simple observation, a quick check with the gauge will immediately tell you which tires need some air (or nitrogen if you're that way inclined!)

We'll now check out a few of the better gauges on the market, see how they perform and ensure that you get the right gauge you need to measure the air pressure of your tyre. 

In this modern era, the best tyre gauges are those with a digital display. Such units properly measure the pressure and give you an extremely accurate reading. This is very important because many tyres perform best when filled with air to the manufacturer's instructions and intentions. 

Take a racing bike tyre.

There's a certain ideal amount of rubber that needs to be on the road for an efficient ride.

Too low a tyre pressure, and there's too much surface tension and you'll be slower. Too much pressure and you'll run the risk of a blowout. It's even more important for races where every second counts. 

Enter the AstroAI Digital Tyre Pressure Gauge:

At less than ten of your Earth dollars, the Astro AI pressure gauge should be right up your ally as a cost-effective tool.

Obviously, this unit is designed to help you maintain correct tire pressure with the goal of reducing tire wear and extend tyre life. 

It features a digital display with the reading being displayed instantly and clearly being shown.

The nozzle part easily forms a seal with the valve stem on schrader valves, giving quick and accurate readings in 0.5 increments; 4 settings with range: 0-150PSI / 0-10Bar / 0-10Kgf/cm² or 0-1000KPA.

The gauge automatically shut off in 30-40 seconds to save on battery power.

Its grip texture makes it easy to hold onto and the ergonomic design is both suitable for anyone's hand.

At less than ten bucks, it's worth having one to sit on the boot of your car or in your mechanical kit. 
But what would we know?

Here are some reviews from real users who have brought the gauge via Amazon and used it:

"I bought this for around $9 from here. First thing I noticed was how cheap it felt in the hands when I pulled it out of its box. Thinking to myself, what a cheap piece of crap I bought. I drove to Costco and filled my tires with nitrogen and put it up against their pressure gauge. Holy moly, this gauge was exact compared to Costco's pressure gauge monitor to the T. I was left scratching my head. How can something so cheap in price and and plastic we were so damn good. I'm 100% satisfied and glad I purchase it. Lol. Thank you Amazon and to this company for a great deal."

Sounds promising then...

"So this is the second tire gauge I've bought through Amazon. The first was completely useless. Didn't measure any pressure. At $5 wasn't worth returning. Sucky. This one is great. Seems very accurate, is extremely easy to use and is great at night. You know you need a tire gauge at all the inopportune times. I love that it takes a reading and holds it so you can bring the gauge to your face, rather than having to squat in a ridiculous position to read the gauge. GREAT IDEA!! It also allows you to bleed off extra air, which I didn't see mentioned - but that works great. This one is A+++++ "

Sounds like we have a winner...

"The ergonomic design makes it easy to hold & the quality for the price is impressive. I used it yesterday for the first time & it was a lifesaver. My low tire light was on & it enabled me to pinpoint which one. I am a 75 year old woman & if I can use it anyone can! By the way, the instructions are well-written & clear.

If those genuine product reviews check your box, check out the price on Amazon:

 If you don't fancy a digital gauge and you want that classic mechanical dial display then the Jaco gauge might suit your needs.
jaco tyre gauge for air pressure
It's a genuinely quality tool that has been performance-tested, certified as accurate, & calibrated to ANSI B40.1 International Accuracy Standards (±2-3%).

This means you will precise tire pressure readings and you'll not need to rely on battery power!

This unit feels solid in the hand as it is crafted from premium heavy duty components and it's shielded by a rugged shock-resistant protective guard.

It also features a flexible no-leak air hose which gives you plenty of room to check the pressure.

But don't listen to us, listen to real users who are very satisfied after field testing the units on their cars:

 "Gauges are well built and very legible. The chuck fits the tire valves well and I did not experience any of air loss common with cheap gauges. These gauges actually swivel at both ends of the rubber hose. No problems using them regardless of the tire valve position. The 100% lifetime warranty is a bonus."

"It's a good size and easy to hold and read as a result. The hose is a good length. But the big question with tire gauges is: how easy is it to seat on the valve of the tire? This one has a swivel at the gauge and another about two inches from the head.... easy to maneuver and easy to get a good seal on the valve and therefore a good reading."

" I checked all 4 tires on my wife's car because her warning light was on. Found one tire that needed air. It was down about 7 lbs. As I moved to a darker part of the garage, the dial face lit up with a bright green luminescence. I didn't even know about that feature. The swivel head and the pressure relief button are fantastic features as well. No more pencil types or digital ones for me."

 Sounds like this gauge as won over some fans. If it floats your boat, check out the price on Amazon:

How to replace a spark plug in a lawn mower

Replacing a spark plug for a lawn mower


Lawnmowers are basically engines with a lethal blade that spins around cutting grass as long as there's gas in the engine and a spark plug that's combusting the fuel.

But if your spark plug looks like the one above and it's overworked and corroded, it's probably not firing properly and it's time to replace it.

You can tell if your spark plug needs replacing can include:

You begin to hear rattling, pinging or noises that suggest your mower's engine is knocking.

You could also find you are using more fuel than you consider is normal for the operation of your mower. This is a key reason to ensure are spark plug is changed regularly as using excess fuel costs you money and you could be spending it on a chainsaw instead!

The classic problem is of course that the spark plug has failed and you cannot start the engine at all!

If the plug is misfiring, you may notice you may feel combustion is not efficiently happening. This occurs due to the aging of the plug.

As a spark plug ignites, there's a 'gap', in which its reach occurs. This gap eventually widens as a result of repeated use under extreme temperatures, normal wear, and tear. If the 'gap' is becoming too large, the unit's efficiency declines and combustion becomes erratic.

How to replace the spark plug in your lawnmower


  • When the engine is cool, remove the spark plug wire.
  • Clean any debris off the wire, ensure the metal is clean of rust etc.
  • Use a spark plug wrench to gently unscrew and remove the plug. If the plug is sunk in tight, do not use excessive force. A bit of CRC or WD40 style lubricant may help. Using the correct sized plug wrench is also very important.
  • Use a spark plug gauge to measure the gap between the two electrodes and make sure the gap reflects the recommendation of your lawnmower manufacturer - check the user manual. 
  • With your hands, sub in the new correctly sized spark plug. Screw it in gently. Then with your wrench, finalize its position with a firm turn but not so the plug is in too tight. 
  • Replace the spark wire, ensure it is correctly connected to the plug
  • Test you've installed it right by turning on the engine. If it fails to ignite, check the spark wire is connected.

Here's a handy tutorial video on how to replace a spark plug:




What is the correct spark plug for my lawnmower?

This was a good question to ask because even though several different spark plugs may screw into your mower, if it is not the correct type your engine will likely suffer performance problems.

If you don't know off the top of your head what kind of spark plug is in your mower - look for the number on the ceramic and match it to the brand. The internet is your friend.

Indeed, you can also take the whole unit into a service agent or hardware store and compare so you have like for like.

The best trick is to look at the user manual of the lawnmower for advice.

It is not imperative that use you use your mower brand's spark plug. You can use a generic substitute or another brand as long as the size and type are correct.

Generally speaking a tried and true brand like a Briggs and Stratton spark plug will work well in most engines.

Battery-powered lawn mowers, of course, do not need plugs!
