An inventor says he has cracked the problem of how to give drivers more grip in the snow without the hassle of fitting snow chains or spikes to tyres.

Czech engineer Peter Gross has created a dome-like contraption that fits over a car's hubcap.

When deployed remotely by the driver, claws flick out and grab the tyre, providing extra grip in snow and ice.

An inventor says he has cracked the problem of how to give drivers more grip in the snow without the hassle of fitting snow chains or spikes to tyres. Czech engineer Peter Gross has created a dome-like contraption that fits over a car's hubcap

HOW DOES IT WORK? The device is a mechanized system that fits over the wheel like a hubcap and can be fitted before a journey. It has four arms that, when triggered by remote control, extend to grab the tyre, deploying steel spikes for ice and plastic grips for snow. Advertisement

He claims his invention is small and easy to handle, weighing no more than 6 kilogrammes (13 lbs).

A promotional video shows the devices working well, extending and fitting snugly to the outside of the test car's tyres.

Mr Gross says he was inspired to invent the device after being forced to fit snow spikes on his car while wearing a business suit and pristine shirt.

He says: 'I was cursing everything, while I was trying to get things done on a dirty road. After that I got an idea about how I could make the lives of drivers easier.'

The device is allowed to be used on 15 and 18 inch wheels and has all the required certification for Europe, the US and Canada, he says.

Details of the product's name or when it will be commercially available were not available.

Netizen 'Tigran Alive' was sceptical.

He said: 'Well, maybe it'll work for Czech winters, but if he goes any further east, I bet it will no longer be usable.'

And 'Dmitriy Sidelnikov' added: 'You can't actually speed up when using these, can you?'
