Registering TPMS IDs

Yes. I think one problem to worry about with the Nordic unstudded ones is if the temperature goes up to +15C or higher and the road surface to +20C or higher, they start to "melt away" pretty fast. Here the temperature stays between +10 and -30 pretty much the whole winter. IMO the studded ones are much more durable.
Snow efficiently dampens the noise of the studs, but if you only get snow 10 days a year...

 

Is that +10C to -30C. Where I live, temperature stays below 0C=32F (freezing) for most part of winter from Dec to Mar. We have had occasional warm January thaw days during winter but that's rare. If you get +10C during winter, that's amazing, I am sure your location, southern Finland, is much further North on latitude than where I live.

 

Is that +10C to -30C.?
Yes.
Gulf stream warms the nordics is the scientific explanation I guess, it throws warm air here sometimes. We are on the same parallel as Alaska.

But the winter season is much longer.
I have winter tyres on from end of October to mid April. Roughly, depending on the winter a bit.

In the spring especially it might be warm during the day and icy at night.
Dec to march it's +3 to -30C I guess.

 

It is fairly similar weather to ours then. Our first frost is usually set in late Sep to early Oct. It doesn't snow much till late Nov, but if we have much accumulation during winter, snow can stay on ground until May. I usually keep snow tires from late Nov to early April.

 

It's a little maddening, the labour expense, time, effort, and wear-and-tear on your alloy rims, twice yearly, in order to circumvent an annual state inspection that would pull the car off the road (if tpms light was lit), all in order to maintain safe winter traction.

 

Yap, you got that one right, maybe except about the expense. It is much more economical to keep both summer and winter tires on the same rims and the same set of TPMS. Fortunately, my current car (Prime) has inspection during summer month, unlike previous Gen3 Pri. I maybe able to get by with TPMS warning light on during winter. BTW, our Civic Hybrid has TPMS light on for the 6th time, but I am not going to fix it until I absolutely have to when it's due for inspection next Jan.

 

Yup. Pretty similar in that respect.
But I'm pretty sure the roads are much worse here.
The temperature can change 30 degrees within one day. From -25C to +5 and then back to -15C all within 24 hours.
Add snowfall or rain...
And that freeze/melt/freeze cycle means icy roads = skull weather.

If you get this for 2-3 weeks per year + all the other hellish weather studs start looking more attractive.
There's so little sunshine that the ice just doesn't melt during the day.

 

I don't see kids outside in the winters here like when I was a kid, kind of sad.

 

Here we are usually super bureaucratic but for some reason we got rid of the tpms rule pretty quickly.
A new car has to have it as requested EU rules, but after that nobody cares about the lights.
Finland got rid of it after one year.

 

Yes, we've had the condition on our driveway occasionally, but usually not on public road on which they salt heavily. We call it "black ice".

 

Yes. That's what we call it too. "Musta jää" is "black ice" in Finnish.
That you can get here all winter long maybe 20-30 days out of the winter.

 

We do get freezing rain occasionally. Precipitation of supercooled water droplets freezes instantaneously when it hit any hard surface like road. That's far worse than any other type of precipitations for drivers on the road. Fortunately, we don't get it that often. If we get it 20-30 days out of winter like you, I am sure there are more studded tires on cars.

 

That's the best part of living up here (there are downsides too believe me.... ).
Kids walk school by themselves from 8 years of age on, even in the Center of Helsinki the capital.
And they still can play outside by themselves.
Nobody looks after them.

And of course babies are left outside coffee shops in wintertime to sleep while the parents are inside.
I read about some nordic person getting arrested for this in the US.

It is still really safe here.

 

Freezing rain on a cold surface creates what is called glazed ice. It's not the same as black ice.

 

Hummm... I am not an expert in meteorological terminology, but according to Wikipedia...
Black ice, sometimes called clear ice, is a thin coating of glaze ice on a surface, especially on roads.
It further states...
The term black ice in the United States is often incorrectly used to describe any type of ice that forms on roadways,
Black ice - Wikipedia

Technicality. Isn't it.

 

Better ask our resident meteorologist. Sorry I've forgotten his handle.

 

Here when the weather warning says "black ice" it usually means that around 0C there is a thin layer of ice and it looks the same as a wet road. So people tend to drive too fast thinking it's wet not ice and get into an accident.
Supercooled water is another thing and then glazed is what I get on my driveway 2-3 months out of the year.

And then we have a couple of other terms...

Finnish words for snow.

Frozen precipitation that is still falling

1. lumi: snow
2. pyry: snow shower
3. myräkkä: snowstorm

1. nirskua
2. narskua
3. kirskua

Dialect words
Some of the above are pretty obscure, but these are downright bizarre. Finns who do not speak the dialect in question (marked in parentheses if known) will not understand these. And note that this is only a small sampling, linguists have recorded literally hundreds of these.

1. hölse: slush
2. höty: loose snow
3. höttyrä: loose snow
4. höyty: loose snow
5. judake: reindeer track in snow (Lapland)
6. klossakko: slush
7. komo: raised ice
8. kieppi: snow pile
9. mora: uncompacted, unskiable snow (Lapland)
10. triimu: snow pile (West)
11. triivu: snow pile (West)
12. purku: snow shower (East)
13. pöykky: snow pile (Tampere)

Borderline cases
Depending on context, these may or may not refer to snow.

1. keli: weather conditions; the "skiability" of snow
2. pulveri: powder; very cold, fine, powdery snow
3. valli: wall, blockage; a wall of snow (natural or manmade)

But guess what?
Despite all this, Finnish lacks the verb "to snow"! That's right, to say "it is snowing", Finns have to state sataa lunta ("it is raining snow") or more colloquially tulee lunta ("snow is coming").

 

I think you mean @edthefox5

 

lol...

 

Did this on my Prime. Nothing displayed. Long hold will reset the TPMS, but nothing on 3 select button. Of course, as you said it, the car has only 4 TPMS registered, so by default it may not look for the second set. I can ask at the dealer tomorrow, but I have a feeling they have no answer for me.
