smart wireless

tyre monitoring system

I'm sorry, I don't know when of if our product will be available again. However, this site has much information on tyre safety. It's my hope that this will help keep you safe when we all get on the move again.

Helps you always run with

tyre pressures that are spot-on

Helps you always run with

tyre pressures that are spot-on

The Big Deal.*

When you run your tyres at correct pressure . . .

 not under-inflated, not over-inflated . . .

You save up to 4% in fuel.


You optimise ride, road-holding and braking.

You enjoy a better, less harsh ride.

You gain 25 to 30% more tyre life.


And you reduce the risk of a tyre-related accident by 3x.**

What's more, our customers are telling us how

WiCaps have brought to their attention serious issues like

tyres overheating, caravan or motorhome being over-loaded.

One customer told us WiCaps made him realise that

his dealer had fitted the wrong tyres to his motorhome.

Seriously, fit WiCaps as soon as you can.

*Figures relate to a comparison with tyres running at 25% under-inflation.

WiCaps deliver convenience & safety . . .

 WiCaps continually transmit tyre data to your phone

(on the move or stationary).

They sense when pressures change.

And significant pressure-change means that you have a tyre issue that you need to address.

Get safe before you start

Before you start a journey . . .

If one tyre has a lower pressure than the others,

WiCap is telling you that you have probably 

picked up a slow puncture.

Keep safe on the go

On the move, if pressures change by more

than a few psi, WiCaps are detecting a problem.

Pressure goes down (from normal to minus 10% or greater %) :

you have an air-leak (generally a puncture).

And you can do something about it.

Pressure goes up (from normal to plus 15% or more) :

you may have an even more dangerous situation.

With caravans, trailers and motorhomes,

load (laden weight) can vary by orders of magnitude.

So it's easy to miss that the tyres are over-loaded.

Or worse, that you have inadequate tyres. 

WiCaps are sensing what you can't see.

And they are telling your phone there's a pressure

change before you find out the hard way.

Warning: it is unlawful and dangerous to look at your

phone while driving.  Be aware of in-vehicle phone-use restrictions.

Let your 'co-pilot' do the WiCap pressure checking.

Heavy load. High pressures.

No problem. 

WiCaps are accurate even at an amazing 188 psi.

That's more than you're likely to need, even for heavy-load-carrying trailers.

WiCap fits all

Two or four wheels, any pressure, any tyre type.

From e-bikes to motorhomes. And coming soon . . .

our own app that monitors up to eight tyres. 

WiCap kits for 2 and 4 wheels

Attractive presentation box.

Why not make this a special gift for someone?

The app

WiCaps utilise a third-party app that is accurate (1%)

and reliable for pressures up to 188psi.

WiCaps have a very comprehensive user-guide in English, written by us with caravan and motorhome users in mind.

Be aware: a current software limitation means this app's

under-inflation voice alarm setting is currently lower than we'd like for higher-pressure commercial tyres.

For high-pressure caravan motorhome tyres,

the important over-pressure voice alarm works great.

The app is limited to two or four wheel applications.


We'd also be happier if the app was a bit more elegant

but we forgive it because it's reliable and super-accurate.


Don't forget, if you find the app doesn't do what you want it to do, you can return your WiCaps for full refund*.

* subject to the terms and conditions (supplied with kit) and subject to you doing, within 14 days of receiving the product, a trial fit of WiCaps while checking the app works OK on your device. Returns are not allowable after that period and we provide no warranty on software.

In development:  our own app

We believe WiCaps deserve a beautiful app with no limitations. Hence, we've been hard at work coding our own app. It's  state-of-the-art software and yet incredibly simple to set up and use. It's even more advanced even than any TPMS you'll find in today's hi-tech cars like Tesla. I just hope you get to use it.
