Weight the categories that matter to you

Wet grip starts at “Important”. Treadwear starts at “Neutral” here: road tests measured it for at most one of the two tires, so it rests on owner reviews. Move the sliders and the scores update instantly.

All owner themes in the Blizzak WS90 review

Tire B WeatherMaster SA2+

Pros

  • Strong value for the price, with several reviewers saying it is hard to beat and would buy again
  • Good wet-weather grip and stability, with a comfortable, soft ride
  • Capable in cold conditions and light or easy snow, and usable across mixed wet, dry, snow and ice on a long trip

Cons

  • Snow and ice performance is only average in heavy snow or on ice, with one reviewer moving to a Nordic-compound tire for extra grip
  • Handling and road feedback criticized, with one reviewer describing fast cornering as scary despite good grip
  • Dry performance is limited, as the tire reportedly overheats quickly and loses grip when driven spiritedly

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.
