“Hey everyone, I’ve owned these tires from almost 5k miles. Had bought these at Costco. Honestly love them. My only complaint is I think I have tire rub. I feel the vibration and noise when there is 2 or more adults in the car. My tire is 225/65/17”

Bridgestone WeatherPeak
Community opinion on the Bridgestone WeatherPeak is largely divided. Drivers praise the tire for its wet traction, snow performance, comfortable ride, and low initial road noise compared to stock tires. However, many users report significant concerns regarding premature tread wear, dry rotting or cracking, noise increases over time, and notable drops in fuel/EV efficiency.

“Major efficiency drop w new Bridgestone Weatherpeaks I recently replaced my worn out stock tires (the OEM low rolling resistant EV friendly ones) on my ‘22 Bolt EV 2LT with Bridgestone Weatherpeak 215/50R17’s mainly due to a sale at Costco Tires. I wanted the snowpeak rating as winter is upon us. However, my efficiency dropped dramatically since, going from an average of 4.5 miles per KWh (even in the dead of winter averaging 30 degrees F) to around 3.1 miles, often even lower when it gets really cold; was even low as 2.9 miles per KWh last week. Anyone else have similar experiences? Read more”

“installed Weatherpeaks on m y '19 Touring at 36,000, April 2024 ; nice & quiet for the first 4,000 miles; turn-in less sharp than the oem Duellers which reduced the tendency to oversteer - (a good thing) Yikes - at 4,000 miles use (40,000 odo) they became NOISY - sound like driving on dedicated Snow Tires ; GODAWFUL FOR HIGHWAY TOURING - tried 3 Rotations over the next 10,000 mi - NO IMPROVEMENT in noise - Last Week - at 14,000 use (8/32 tread remaining) one tire got a road hazard "blister' & needed to be replaced (Now COSTCO no longer sells them & can't won't honor warranty) ..." just buy 4 new tires , please " p.s. COSTCO still put the "blistered" tire onto my car on Left Frt - so apparently it was not seen as a huge hazard to them ??? so, January 2026 , i decided to replace WITH PRIMACY TOURING a/s - YIKES constant road NOISE is even worse than the Weatherpeaks !!! even in a parking lot & smooth city streets Will probably put the Weatherpeaks back on cuz i get still get one (10/32 new) from America's Tire”

“Bridgestone Weatherpeak worth more than Michelin Pilot sport all season? Finally it's that time - new tires :( I happen to live close enough to costco, so I'm leaning toward getting tires from them. I was looking at Bridgestone Weatherpeak, because i've been using Bridgestone tires for as long as I can remember, but I saw michelin pilot sport all season 4 for roughly $100 cheaper (for 4). I don't mind spending more if it's worth the extra cost. Just for some info. it's a 2019 impreza, and I live near Seattle. Not a lot of snow, but mostly rain. lots of rain. We have a separate car that we drive for more rugged weather and train.”

How do we compare tires?
Every category score blends two independent signals. 60% comes from professional tire tests (braking distances, lap times, noise measurements), each result compared with every other tire in the same test and newer tests counting more. 40% comes from owner reviews found online, adjusted for how generously each site rates. Both use one scale: the average tested tire gets 70, the best 100. When a tire has only one of the two, the missing half is estimated from the other and the score stays closer to average; with no road test and fewer than five owner reviews it gets no score yet.
Handling is the exception: road tests measure it inside the dry and wet scores, so its own row comes from owner ratings only and starts as less important.
