Purchased on October 31, 2019 so three winters for a total of 59791 km. They are completely finished after only 3 winters...normal? Install November 1 and removed April 1 each year. I don't have a sporty driving style. (60 years)

Best Winter Tires available for sports coupes or sedan! Been using 1 month in CDN winter. Handles like a summer tire on dry pavement in winter temperatures. WHISPER quiet too. When there is snow - traction is 5/5. treadwear on the GSI is amazing. the previous gsi5 model got 100 000km so these should be the same or better. Dont look else where. The siping goes all the way to the bottom too, unlike most winters so they will be good for a long time! no complaints whatsoever

Given 100% while driving a Honda Civic Si Sedan (215/55 R16) on mostly town for 100 average miles
Previously I owed Toyo Garit winter tires (no longer available) and I was absolutely amazed with the winter grip, braking and cornering. in October 2022 I purchased Toyo GSi 6 tires for my Honda civic sedan. The first winter storm in Calgary Canada quickly paid for them. I was able to momentarily brake and then quickly steer clear of a an unexpected vehicle and bus interaction in front of me. Yes, you can always driver more defensively to avoid these type of interactions. This time I wasn't and couldn't. My daughter as a passenger said "how on earth did you just do that! I simply shouted in delight "Toyo GSi 6s Baby!"

The Observe GSI tire has no equal, there may be studded winter tires that outperform them on ice but from a daily driving POV you cannot beat these. Finally had to recycle mine after over 100,000kms. Will buy another set this winter for sure.

Given 79% while driving a Hyundai ix35 (225/60 R17) on a combination of roads for 5,000 spirited miles
Overall good winter tyres. Pretty good on dry and wet road at autumn temps taking into account these are winter tyres. Slightly blurred "zero" steering position at town speeds. Tyres of this size have rim protector which not every tire has and sidewall is moderately stiff. Snow pull is good to excellent. Handling on ice and mixed snow/ice is very stable while feedback is exceptional. You can definetely say when where tyres will start to slip. Ice grip is great for friction winter tyres. Overall feeling is better than more expensive Nokian Hakkapellitta R2.

Audi A6, 3.2L, Quattro (225/45 R18) on a combination of roads for 100 spirited miles
Snow in Sweden and below 0C, replaced my old worn down studded Hakkapelitta. Must say im impressed by the grip of the tyres in snowy conditions so far. A bit noisy in my opinion but performs very well overall. I recommend them.

Given 91% while driving a Volvo V60 T6 AWD (235/50 R17) on a combination of roads for 10,000 spirited miles
I had these tyres installed prior to picking up my new(to me) V60. Drove the car from Montreal to Halifax. Initially on dry roads with temperatures below freezing. What first struck was how quiet these tires are. Not just for winter tires but also compared to the all season Continentals I use for summer driving. The next day I drove in blizzard conditions(driving snow on uncleared highway) which eventually turned to slushy(wet snow) roads then finally wet roads. So within 24 hours I was able to test these tires in every winter condition other than hardpacked ice. They performed flawlessly and were confidence inspiring. Very stable, quiet and responsive. Very happy with these tires and would recommend to anyone.

Given 89% while driving a BMW 320D M Sport (225/50 R17 V) on a combination of roads for 6,000 spirited miles
Bought these tires for girlfriends bimmer with 2 sizes down for more comfortable driving in winter conditions. Comparing to Goodyear’s UltraGrip ice 2 on my Lexus toyo’s grips in the same way but they are a lil bit louder and firmer, I think it’s because of speed rating. As for thread life rear wheels lost 1mm of pattern, maybe because I drive it spiritly. Anyway tires for such price is definitely good choice for winter time. Just ordered a pair of Toyo for my Lexus front axle.

Given 100% while driving a (235/45 R18) on a combination of roads for 1,500 spirited miles
These are snow tires, there should be a "Snow Grip" and "Ice Grip" score.
The traction on snowy roads, compact as well as fresh loose snow is excellent, on icy roads it's also very good for a non studded tire. Great acceleration, but more importantly excellent lateral stability while turning and great braking!

Very impressed with these GSi-6 tires, my previous tires were Nokian Hakkapeliitta.
