Bicycle Tire Pressure Gauge

Presta Tire Gauge

Many car tire gauges don't go high enough for higher pressure bike tires. For mountain bikes, you would be fine as long as your tires have the same type of valve as a car tire. If you have a road bike, especially if you have presta valves, you may have to buy a gauge. The best thing to do is to buy a good pump with a pressure gauge, and use that to simultaneously check and top up your tires. Tires need to be pumped fairly often, the narrower the tire, the more often it will need attention

If the pressures are within the range of the gauge, then it will be OK. Very often car pressure gauges don't go as high as the pressures on bike tires. I had to buy a "truck tire car gauge" to get high enough pressures for a bike that I owned.

Lots of bikes have a valve stem that isn't compatible with car valve stems. It's easy to tell because the two valve stems don't look anything alike. If you have the "different" valve stem, then you need a $2 adapter to be able to use a car or truck pressure gauge. You'd need the adapter anyway just to inflate the tire from a car-type air pump.

A car tire gauge will work fine on a valve with a shrader valve that is the same thing a car has. If you have a presta valve that is common on road bikes you will need a special gauge. The best thing to get is a bicycle pump with a gauge built in. I usually go by feel and never use a gauge.

Yea, having a foot pump at home with a quality gauge will ensure that you leave home with the right pressure. But what when you fix a flat on the road?

A gauge is only accurate on the middle of the range it measures, if you need 40 PSI you should buy one that measures up to 60 PSI, if you need 50 PSI get one that measures up to 80 PSI, if you need 100 PSI get one that measures up to 140 PSI. Also a gauge can get damaged if subject to more pressure than it is supposed to measure.

This gauge from Amazon seems interesting and light weight to carry with your tools on the road but the max reading is only 99.9 PSI, so it will not do any good for tires that require 100 PSI and it will get damaged very easily.

A car gauge will not work on presta valves without and adapter.

possibly

but also they may take a lot of air out of the tire, lowering the pressure

it;s best to have a gauge with the pump, and just check as you pump

that doesn;t let any extra air out just to measure the pressure

road bike tire pressures may be higher than a car gauge can measure

I just bought a car gauge to use on my bike but it only went up to 50. I usually put in 65 pounds for my bike, so I will return the car gauge and get one for a bike. So yes it does matter!
