I roll in whatever the day brings, it's not been bad enough for me to opt out of riding other than when I've been sick/recovering from sick. I just try and stay more upright and take it easy in cornering. I'm running a 25 on the front and a 28 on the back, I seem to get by just fine cutting through - it's when the hardpacked/refrozen snowy/ice starts that I start to get more concerned. I took my temp. conversion out in the snow the other night just on my street - lots of fun on platforms with backwards pedalling and such There are skidmarks a plenty in the snow on my driveway right now, being a kid again rules
