Ideally you should ride these on the road before hitting any ice in order to bed the studs into the tyre properly. So you can ride the tyres on other surfaces other then snow and ice. They still have deep channels in order to cope with water and loose surfaces so you should be fine if you aren't pushing it too hard on hard, slippery surfaces.

I would advise an extra 10mm clearance due to wheel flex etc.

I bought the Marathons for last years winter and I was mighty impressed with the grip. They were a little wider than the 32c tyres but not by much.
I have the slimmest mudguards from SKS on my bike and I had to tweak the fasteners a little because they are made for 20 - 28c tyres.

The spikes doesn´t stick out over the sidewall so that´s no problem.
Be careful to run them in proper on bare asphalt, I got mine a little late and had to run in icy conditions. Therefore I lost 1 spike out front but the 239 left is enough.

Also surprisingly smooth wintertyre but expect spiked tyres to run with 10 - 15% more rolling resistance than a tire with road pattern !
But that just makes you stronger and you will fly when switching back in the spring !

These tyres are sold individually.

Unfortunately we are still awaiting an update for the delivery date on these tyres. Demand is very high at this time due to the extreme weather in many areas of the UK so we are currently unsure on the delivery time.

it depends on your wheel width e.g.
700 x 32

Unfortunately we are unable to get this for you as we can only get hold of the items we list on the website.
