Keeping tyre pressures in check

Christmas sales have been so amazing that we've run out of stock. Our apologies. Please take a look at our site and email us at if you'd like us to let you know when our low-cost wireless tyre monitoring system is back in stock.


If you are an existing customer and need product support meanwhile, don't hesitate to contact us at the above address.

Hassle. Risk. Cost. Sorted.

Checking and monitoring tyre pressures:

Something we all mean to do.  

But we don’t do we?

Because it’s a hassle.

And it's impossible on the move.

Now we offer a low-cost antidote

to the costly (and dangerous) consequences of running tyres

at the wrong pressures . . .

A product that simply replaces

the valve caps on your wheels.

A product that continuously

and accurately radios pressures from your tyres to your iPhone*.

*Owing to a series of recent Google updates to Android, many apps  have experienced 'issues'. The third-party Android app used by WiCap has suffered from this and, as a result, currently only works with Android versions 6 and 9.  iOS (any version) for iPhone or iPad works just fine.

A must for motorhomes,

caravans or anything else

you tow: horse trailers, boat trailers. In fact, any trailer.

Fantastic offer

As a special promotion, we are offering an amazing 50% discount on published prices if you have a voucher code.
