Observe GSi-5, Winter Studless

Considered the best overall studless snow tire available, the Observe GSi-5 delivers a safe, secure ride in challenging conditions, even slushy, snowy, rutted roads. With sizes for passenger cars, light trucks, crossovers and SUVs, this winter tire has a directional tread design for stability and improved traction during braking and acceleration. Large, saw-toothed tread blocks and the ultimate in siping technology ensure maximum grip for cornering and stopping. The specialized rubber contains walnut shell for added snow and ice traction and remains soft in extreme cold. Wide lateral grooves clear slush out of the tread with efficiency for greater control.

Owners of the Observe GSi-5 rate it above other winter tires they’ve tried, and praise its extended tread wear, the way it bulldozes through snow conditions, and the smooth ride. This is a tire for the driver who wants confident winter handling no matter what’s happening with the weather.

Rated 5 out of 5 by from Great Traction I am glad I got these tires. In Southern Deschutes County, Central Oregon, we get Winter weather about 1 month before expected I've seen snow in May. These are my first studless tires.

Rated 5 out of 5 by from Winter in Montana We live in Montana and our cabin is 1000 feet above the town of Lakeside, we drive a Ford Escape to town, the last 700 feet to our cabin is straight up just after a hairpin curve. Winter company have to leave their car parked below and we shuttle them back and forth. No carrier delivery in snow season. Until this past year we changed out the street tires to studs. Read about these tires and decided to give them a try. first time I've not had to pay for changing street to studs and studs to street. $140 a year savings alone. As the weather changes from dust to rain, ice, snow, ice, back to rain. these tires hug the road and we now travel up and down with ease. HIGHLY recommend them

Rated 5 out of 5 by from What a huge difference!! I bought snow tires after Christmas to prepare travel over Mt Hood and ski areas. My winter driving confidence soared. Ice and snow travel a piece of cake.

Rated 5 out of 5 by from Legit Snow/Ice Tires Purchased these tires as I needed to get home for New Years, in 24+ inches of fresh snow. With cars off the road everywhere, I felt like I was driving on dry pavement. The traction control and ride comfort are absolutely amazing. Have already recommended these tires to friends and family.

Rated 1 out of 5 by from Do NOT compare to having studded tires at all. I drive excessively as a Mobile Notary Signing Agent, and I have found that these tires function fairly well at 27 degrees or colder. They do not have the grip of studded tires on intermittent ice, snow, black ice, clear road surfaces like the road surface of HWY 66 between Klamath Falls, Oregon, and Ashland, Oregon. I had already lost money in the first week of my using this tires, and so I had decided to go ahead and run them. But I will NEVER buy them again.
