So I currently commute about 6 miles each way come what may-right through the year no matter what the weather-I ride a cross with 700c summer time and switch to a mountain bike 26″ wheel winter time.
Any advice re winter tyres (with or without studs) for either bike would be greatly appreciated!

Thanks

Slicks for 95% of the year. You can ride with slick on snow if you are caught out and they grip just as well as most other tyres in the wet when you are on tarmac.

If you know it is going to snow then some cx tyres would see you right. The studded tyres are heavy and expensive. Might be worth having in reserve but I wouldn’t out them on unless you are expecting issues. Some xc race tyres would also be good for the mtb. Quick enough yet providing grip. I assume you aren’t going to be looking for anything technical so you just want a bit more security on roads and tarmac?

I commute year round. Mostly on slicks. I take my mountain bike if I know it will be bad. Mainly because it has a lower gear and is more stable if the conditions are bad.

The only time I really come unstuck is when it is icy but then I just try and modify my route a bit. Most roads are gritted and fine. There are a few dodgy small ones but when it is snowing you can often get a better ride heading off the well trodden routes as fresh snow is good for grip.

700c GP 4-Seasons?

26″ Schwalbe Tabletops! They just have soooo much grip its insane. Excellent for tarmac and dirt the rain hardly changes the grip at all, beyond lethal in mud though they basically aquaplane 👿

Thanks for the advice Guys. Until recently I did the whole 95% slicks thing but I now tag my 3 year old part way so am probably more an 80/20 split now-any other opinions on the 700c GP 4 seasons? are they likely to keep me off the mountain bike for any longer?
