summer/winter tyres

[alanshaw]

Have 718 Cayman 20" summer tyres fitted, keep on getting OPC emails advising to get winter set of wheels/tyres & they will act as wheel/tyre hotel. I agree do need winter tyres, but not driving car if under 10 degrees or in rain @ the moment.
Have many 718 owners swopped tyres......is it worth it ?
If I get ALL weathers tyres will my car warranty be an issue ? & can anyone recommend any

Not really a car specific question, and que the normal nonsense 'I have never had winter tyres on a car for 53 years blah blah blah'

In slippery conditions it is night and day driving on winters vs summers, so for me it's pretty simple; if you plan on driving on snow/ice - you 'need' winter tyres. If you can do without the car in wintry conditions - don't bother.
