I do ride them daily and they are fine, but I found out that tire choice definitely has to do with it. IRC Metro Duro's were horrible and made me feel like my back wheel was slipping sideways all the time. Vittoria Randonneur Pro's are somewhat better, but not when the pavement (or tire is wet).
However, my Schwalbe Marathon Supremes don't seem to care: Dry, wet, snow, they take it all without the squiggly feelings that the other tires had. This tire seems to have a surface compound that provides a lot of grip in all conditions, but doesn't slow you down. Best tire I have ever had
