After 3000km (1900 miles) of mixed winter wet/dry and surprisingly recently, snow driving, I’m still happy with my decision to go with the Toyo Observe GSI 6 HPs. I was mostly expecting a performance tire suited to the wet, hilly, and sometimes snowy conditions of the west coast, and these tires haven’t let me down. While they aren't as aggressive or responsive as my previous Nokian Hakka R3s (AWD vehicle) in deep snow or extreme conditions, they're much quieter and still provide a great balance of grip, braking, and overall predictability across slush, ice, and fresh snow.
The Toyos have been great on everything from icy hills to twisty backroads and high-speed highway cruising. Their overall performance in mixed speed/road conditions has been impressive! As far as wear goes, after 3000km, I’ve noticed the tread depth has dropped from the original 10mm to 7-8mm in the front and 8-9mm in the rear. While I think this is reasonable (18-20%) given my driving style and road conditions, I’d be curious to see other users’ experiences and tire wear data to see if this is typical for this tire, especially with as my data comes with spirited driving over a 2-month period.
I’ve also been pleasantly surprised by how comfortable these tires are. They’re quieter and more comfortable than my Hakka R3s, even with the stiffer sidewall and higher PSI. The overall ride quality is great for both everyday driving and when pushing the car a bit more. So far in the early mid-life of these tires, the Toyos have been a solid choice, and I’m looking forward to a longer-term update as I continue to drive on them.
