Oh and be doubly careful with metalwork.
... and cobbles!
The most off putting noise is the sound on Tarmac, you won't be sneaking up on pedestrians or other cyclists!
Dogs are looking very confused, too, when they hear the strange creature approaching - some say it sounds like bacon frying, other think it's more like rice crispies when milk is being added and they crackle & pop

3rd year on ice tyres here, invested in a new pair this year as one of the old tyres was dead, and I decided to get the 200+ stud version with my daily commute which involves quite a lot of hills with ice.
When there was unexpected heavy snowfall on the higher ground south of Edinburgh a couple of weeks ago (2-3 inches settling very quickly), there was chaos and gridlock on the roads, with cars sliding on all bit the shallowest uphill gradients. The ice tyres were rock solid on a steep-ish wee downhill convered in in snow - on the separated cycle path, but then again I didn't try speeding and took the corner at the bottom of the hill slowly ...

As somebody said earlier, the worst bit with icy conditions is the potential for big metal objects to slide uncontrollably, and their operators often not driving sensibly and taking account of the conditions.
I've also got a pair of 'granny crampons' in my pannier at this time of year, if I ever need to get off and walk under icy conditions - they weigh next to nothing, just go on over normal shoes. We got ours at LIDL a few years ago, haven't used them very often but lifesavers on rare occasions - pavements in Edinburgh can be lethal
