Firestone Weathergrip All Weather 205/65R15 99H XL Passenger Tire

Purchased and installed by my local Firestone dealer early January 2020 for my 2014 Honda Accord Sport (FWD sedan). I consider Blizzak as my winter tire benchmark and enjoyed that tire in the past but didn't want to hassle with swapping them out. I coudn't find a review of snow/ice performance before my purchase and took a chance given that the tread design is similar to the Blizzak with an all-season rubber compound. I average 30k mi. per year, mostly highway. Driving in northern Illinois, Iowa, and Wisconsin since purchased has given me good experience with snow/sleet/ice/wet/dry behavior. Dry: Good feel, not too soft or spongy, quiet, comfortable. Overall good. Wet: Decent wet traction with slight understeer when pushed. Fairly stable and overall good. Snow: Really good snow traction at both slow and highway speeds. Good grip for starting, cornering, and stopping. Ice: Really good ice traction, similar to Blizzak performance. Really stable starting, cornering, and stopping. Very secure. Walking/slipping on sheets of ice to get into the car then driving away with ease was a common theme. Sleet/Slush: Very common on roads and highways, very stable performance. Excellent behavior and allows for passing in an uncleared highway lane (FWD sedan). This tire exceeds all of my expectations. It does exactly what I hoped for and have wanted for years. It gives me very good snow/sleet/ice traction in town and on the highway while being confident/quiet/stable in normal dry/wet pavement. Curious how long the tread actually lasts and how the next winter will feel so the durability rating isn't based on 3,500mi of experience but an expectation that at 40k-50k mi the snow/ice traction will be reduced.
