So I got my commuter ready for the morning with all my work gear ( panniers and stuff )( 700*28 smooth road tyres), looked out the window at 430 and saw the snow so didn't want to risk it and just took the car,, tomo I plan on taking the MTb with regular knobblies on , do these work ok in the snow , iv never ridden in the snow before , so du think its a goer or do I have to drive
