I got a spare set of wheels with my bike, I was going to sell them on, but now have a better idea, keep them and fit them with winter tyres, basically a road going, road legal mud and snow tyre for the wet and cold of winter. So, can anyone advise me of what would be a good choice of M + S tyre for the XF125GY-B, Pulse Adrenaline ?

I have also considered the question of interfering with the drive train by switching wheels, and think all I need do, is remove the rear sprocket and re-torque it onto the new wheel, either that or get a second chain and front sprocket, as I have a spare rear sprocket I could use just for the M+S tyres. Which way would be better, or doesn't it matter ?
