Keeping tyre pressures in check

Sorry, due to the Coronavirus situation in China, where we source WiCap components, we are out of stock.

Currently, we do not have an expected in-stock date.

If you wish to purchase, please email us and we will inform you when we have WiCaps available again.

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.
