4 patches of rubber touch the road.. Why would you not want to increase traction and lateral grip?
It was that kind of scaremongering and salesman hand wringing that led me to buying Uniroyal Rain Experts in that biblicaly wet Summer a few years ago. They almost had me in the crash barriers on a dry shellgripped* corner!
Seeing as I'm more likely to remember to drive like a nun in the wet/snow/ice than on a sunny warm day (I wasnt going fast at the incident, well under ant speedlimit or visibility based measure of too fast anyway) then I'm sticking with normal tyres.
Confirmational bias, sales patter, scaremongering and probably a slight benefit under some conditions, the frequency of which are open to debate.
*thats what its called, the beige topping they put on junctions?
