Recognizing This Tire Symbol Might Save Your Life This Winter
We dive deep into the standardized tire test that might make all of us a little safer on winter roadswww.outsideonline.com
The 3PMSF for the European market is based on braking test also, instead of an acceleration test for the US/Canada 3PMSF test. A 3PMSF tire that is sold in both EU and US/Canada, I would have more faith in.This is the key:
First published in 2021, the resulting International Organization for Standardization (ISO) 19447 test specifies a course that, “shall be flat, smooth, polished ice and watered at least 1 hour before testing.” Air temperatures measured 3.3 feet above the surface must be between 5 and 39 degrees Fahrenheit, while the surface of the ice itself must be between 5 and 23 degrees. The standard also instructs that weather conditions like precipitation, blowing snow, and direct sunlight must be avoided.
I say this all the time that cold dry textured ice in a continental climate like Colorado is completely different than ice that is “polished, smooth, and watered”, which you might encounter in an arctic climate driving on lakes or in a maritime climate. If you don’t drive on ice that is polished, smooth, and watered it might not be all that relevant to buy a tire designed for that.
Assuming that performance makes it superior in all conditions….is false. It makes it superior in those conditions.
The article also says that a tire manufactures testing symbol for 3PMSF is “useless” but a tire manufactures testing symbol for ice “might save your life”. And that studs are worn and almost useless with 1,000 km on dry pavement. Ummm…that’s not how modern studs work.
Ice rated tires are a good idea though, even though you are still just trusting a tire manufacturer to not put that symbol on a tire that shouldn’t have it. Kinda exactly like that other symbol.
maybe wrong thread but slowing down to go back to ones lane is sometimes the best thing to do ...
Subaru WRX Driver Overtakes a Truck, Slams Into a Snowplow, Car Gets Sliced in Two
NYSDOT uploaded a video of a Subaru WRX slamming into a snowplow on a road covered in snow. Luckily, nobody was injured in the crashwww.autoevolution.com
That's how Continental saves money with the General Altimax Arctic line, they give new life to old Gislaved tire moldsThat would be a good way to save money. ^
from my readings it's a mix of all the above. Different tires for different markets, same tire rebranded, etc.In the tire (excuse me, tyre) test video above some are not, or not yet, available in North America. Do the tire companies make different tires for different markets, or the same tires with different names? I'm sure some of both. I'll be ready for new tires in a couple of years, and I want all-weathers with both the snow & the ice symbols. Continental's only current all-weather North America offering is a cargo van tire.
Studs comment above...several years ago I guy I worked with lived on the coast in Norway above the Arctic Circle. He said that the standard practice there, and then, was to take the winter tires to the local shop for new studs with sharp edges and suitable length at the start of every winter.
Even Colorado ice, or the Wyoming ice I'm more familiar with, will be polished slick at intersections where about a thousand cars have spun their tires before I get there.
Depends what you are optimizing for.So a side comment I pondered given I just bought (but need to have installed) some Pirelli Scorpion AS Plus 3s ...
They're coming with road hazard (effectively free) but pondered if anyone considered a 5th rim, an extra tire, just in case of a dead tire. Simply rotate between the 4 and if every 5K, wear not likely an issue. I suppose 6 would be better.
Generally it's a nit as I only once had a dead tire that couldn't be repaired and didn't have issues with getting one. But AWD today with sensors and such seem more picky on matching for wear .. or at least the dealers holding a harder stand on replacing at least 2 if one dies and mileage is up.
plus on longer trips (at least with a bigger vehicle) one has a full size spare if they care to haul it.
