Bicycle winter tyres

Updated: 09/09/2020.

Cycling in the winter, even on snow and ice can be nice. 🙂  Having good bicycle winter tyres helps a lot in that! This post will explain basics of tyre traction. Then types of snow and winter surfaces usually encountered. Afterwards it will tell most about studded bicycle tyres and their attributes. Finally, it will help you choose the right type of bicycle winter tyres for your riding conditions. Let’s start.

1. Tyre traction on the road surface

Tyre traction on the surface depends on how sticky the rubber compound is for surfaces that the tyre can’t dig into. That is why for paved roads, whether they are dry or wet, the best tread profile is slick, bald, without any grooves. If the tyre leaves impression on the ground, that means it can dig into the surface and that is when the tread pattern comes into play.


2. Types of “snowed” roads

There are three basic types: soft snow, slush and ice. Explanation of each “type” will be given, before recommending tyres for each (some tyres are more universal, but each have their strong and weak points – can’t have it all).

2.1. Soft snow

By this term it is meant the soft or lightly trodden snow, of various depths.

Soft snow. Above 20 cm makes riding very hard - walking is faster. :)

For snow that is soft, tyres with deep tread pattern, knobby tyres, offer the best grip and traction.

2.2. Slush

Slush – watery snow, usually in the streets that are ploughed, with, or without a very thin layer of fresh snow – a few centimetres or so.

For slush and shallow snow, narrow tyres that can easily cut to the pavement are the best choice. Moderate grooves can help tyre reach the pavement and get a grip.

2.3. Ice

Ice – whether of highly compressed, trodden snow, or frozen water.
For ice, when it comes to rubber tyres, the best choice is bald, slick profile, since the ice is hard and tyre cannot dig into it – so it behaves like slippery concrete. That is where studs come into play.

3. Studded tyres?!

Winter bicycle tyres with studs built in. Studs for bicycle tyres look like this:

As can be seen in the pictures above, the studs are with a flat, cut off tip. The quailty ones have a carbide core. These studs are the only good ones because they don’t get damaged from riding on pavement. One will often cross parts where the snow is melted and there’s bare pavement underneath.

In addition, studs are usually not placed in the middle of the tyre. This enables rider to just inflate the tyre and have the studs barely touching the concrete, in case the snow melts and there’s a long stretch of bare pavement.

When riding in ice and snow, it is always recommended to lower the pressure a bit, make tyres a bit softer. Tyres will then bend more in contact with the ground and studded tyres will have the studs come in solid contact with snow and ice.

3.1. How do studs work?

In the snow, studs have no effect whatsoever. They neither help, nor reduce traction.

On ice, studs dig in and allow good traction.

The physics are simple: studs are very hard, with relatively small tip. This means the weight of both rider and bicycle is put over about 10 small dots (whatever number of studs come in contact at one time). So relatively high pressure is made in the place where a stud contacts the ice. With increased pressure, water turns to fluid from sollid state, so studs do micro-melting of ice, just enough to dig in, with the surrounding ice staying firm, enabling a good grip. The same principle that ice skates use.  🙂

In practice, riding on ice with studded tyres gives a feel of riding on dry pavement with ordinary tyres. One can even feel safer riding than walking.

On one occasion, after a 30 minute ride on ice with studded tyres, I almost fell when I stopped and started to dismount – I had completely forgotten that it was icy and slippery, so when I put my feet down…  🙂

3.2. Studs on pavement

On pavement, studs reduce traction. They can not dig into concrete, and metal is more slippery than rubber. That is why studded tyres are made without studs in the middle part of the tyre. When riding with studded tyres on pavement, one should be gentle when cornering since the studs are mostly at the sides, so no hard cornering or leaning the bike a lot. Normal, relaxed riding and cornering will work like regular rubber tyres on pavement.

Avoid hard accelerating and hard braking (if possible). This is not (only) due to poor traction, but to avoid studs being torn out of the tyre. There are replacement studs available, rather cheap, but why waste them? They can take hard riding on snow and ice, but not on pavement.

In practice, studded tyres will work just fine on pavement, with a slightly less aggressive riding style. Just some common sense and caution and riding will be just fine.


4. Which winter tyres to choose?

  • First question is do you encounter ice, even occasionally on your roads?
    If yes, then it is very good and safe to choose tyres with studs. If there is no ice, studs are not needed and not useful at all.
  • Second question is do you ride in deep snow?
    If you do, then choose tyres with aggressive tread pattern, fat knobby tyres. If the roads are regularly ploughed, or snow is well trodden (by cars or other road users), then choose less knobby tyres – because the wheels will roll better, easier and traction on parts where you encounter clear pavement will be better.

There are practically four combinations of different surfaces and I’ll recommend a tyre for each. Links on tyre models lead to a search for on-line shopping at Amazon.com.

4.1. Ice and deep snow

Tyres with aggressive tread pattern and studs. They grip well in deep snow and studs help when ice is encountered.

Good models are Suomi WXC300 (for MTB 26″ wheels), Suomi W240 (for 622 wheels – 28″ treking, 29″), or Suomi WXC´R 312 (for 27.5″ wheels).

4.2. Ice and shallow snow (or regularly ploughed roads)

Tyres in the picture are the ones I use in my city. The model I’d recommend are Schwalbe Marathon Winter – in size that fits your rims and width as narrow as you can find.

4.3. Deep snow, without ice

Tyre with aggressive tread pattern and no studs. Good for deep snow and mud.

Any tyre with aggressive tread pattern will be good. Big room between knobs allows the tyre to clean itself of snow and mud and always grip well. Author’s recommendation are Continental Race King tyres, in width and diameter that suits the rims on the bike (26, 27.5, or 28-29″ wheels).

4.4. Shallow snow, without ice

Tyre with fine tread pattern without studs.

Tyre with fine tread pattern will be fine. Tyres with compound made for winter (softer rubber) will be better.

I’d recommend Continental Top Contact Winter II Premium, width and diameter to match the bicycle’s wheels.
