I’m running 245 Dunlop Wintersport M2’s now.
They’re really weird tires. In the snow they’re ok, much better than stock.
On wet roads they’re amazing. They grip like my stock tires do in the rain.
On dry cold roads with that little bit of salt dust, they SUCK. You’d think you were driving on ice. Maybe not quite that bad but I can spin them WAY too easy.
