I put the Nokian A10 studded tires on my bike this weekend and also added some retroreflective tape to the rims and a bit more to the rear rack, completing that project, too.
I did a test ride last night and didn't think the studded tires were too bad.
This morning's commute was longer, though, about 5 minutes longer than normal, with speed about 1.5-2.0 mph lower than I would normally do. The A10's do have higher rolling resistance than my summer tires, my thighs can confirm this. The peace of mind knowing I am prepared as well as I can for winter weather is worth it, though.
It is time to start saving for a second bike, so I can choose the one with summer tires if the weather won't dip below freezing on a particular day. For now, though, I will just work harder pushing the studded tires and consider it good exercise and "character building."
