The Viair 85P 12 Volt tire pump is a capable and well-built compressor that provides reliable inflation performance. It has been specifically designed to be a high volume style of compressor and so is ideal for car tires and general inflatable. There are plenty of pros for this device, but check out the cons as well as it may affect whether it is the pump for you.
- Fast and quiet operation
- Multiple nozzles with on-pump storage
- Screw-on tire connector
- Maximum 60 PSI so not suitable for most bicycle tires
So How Good is The Viair 85P 12 Volt Tire Pump?
The Viair 85P 12 Volt Tire Pump is a great heavy use inflator for car tires and a number of other high volume inflatable jobs. Inflation is fast and relatively quiet and it operates happily from a cigarette lighter. Just one word of warning though, make sure the engine is running before you plug it in. It does tell you this in the manual, but I didn’t read the manual before I first used it and blew the cigarette lighter fuse in my car.

The Viair 85P 12 Volt tire pump uses a 12V DC cigarette lighter connector in order to provide power to the device. While this makes it ideal for taking out on the road and for pumping up car tires, it does mean that if you want to use it for other applications (such as for bicycle inner tubes) you will either have to pump things up near your car or, which is what I did, buy a power converter to use it from a mains socket in the house.

Nozzles and Valves
The main nozzle for use with car tires is a high quality brass screw-on nozzle. I have found this to lead to very little air loss at connection and disconnection compared with the more common clamp-on type of nozzle. The VIAIR also comes with a needle nozzle for balls and two sizes of plastic nozzle for the high volume tasks. I have used the needle to blow up volleyballs and one of the plastic nozzles to blow up my exercise ball. Both tasks were completed very quickly.

Unusually for a built-in pressure gauge this one is actually accurate enough to use to measure bicycle and car tires pressure. Just stop the pump and read off the gauge. This makes it perfect for use on the road and even on my track days when I am pumping up tires three or four times a day.

The Viair 85P 12 Volt tire pump is a great general purpose pump when used for car tires and general inflatables. However it is not suitable for some bicycle tires because of the low pressure rating of the system. I tried partially blowing up a bicycle tire with it once, just to quickly get it up to 60 PSI, but I blew the fuse in the pump and so haven’t tried it again. Fortunately the fuse is easily accessible and replaceable.

In my opinion, this is a very capable pump and is ideal for car tires, balls and airbeds. Unfortunately, the main problem I have with it is that it is not capable of providing the pressures required for my bicycle tires.
