What real owners are saying

From Reddit, forums and review threads. Not part of our score

Tire A

Bridgestone Ecopia EP300

We haven't collected enough community discussion about this tire yet.

Tire B

Bridgestone Potenza S001

Mixed

Community sentiment regarding the Bridgestone Potenza S001 is predominantly mixed to negative, particularly concerning the run-flat variants. Drivers frequently report stiff sidewalls, harsh ride quality, road noise, premature wear, and tread cracking, leading many to switch to non-run-flat alternatives like Michelin. However, several owners find them adequate for spirited driving, citing satisfactory dry and wet grip as well as acceptable ride comfort on specific vehicle setups.

“I run the Bridgestone Potenza S001 Ultra-High Summer Peformance Tire 215/45R/20s on the rear and 195s on the front. They ride softer than stock tires. Not cheap tho.​”

“Bridgestone Potenza S001 all year in Portland Oregon? As a second car in the family, do you think I can get away with running Bridgestone Potenza S001, with good tread depth, all year in Portland Oregon? I've lived here my whole life so I know the climate well. As long as I don't drive during the 1-3 snow days, do you think I'm good? My other car is a Honda Pilot AWD that we do summer/winter tire swap and take skiing ~20 times a year. For a car I never plan on taking in the snow, doing summer/winter swap or summer/all-season seems like overkill.”

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.
