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.

Pros, cons & observations

Themes extracted from owner reviews found online — not the opinion of TireWheelGuide.

Tire A SP Sport 01 AS

Pros

  • Exceptionally quiet, smooth, and comfortable ride quality
  • Surprising and reliable traction and handling in deep snow
  • Good overall braking and grip performance compared to previous tires

Cons

  • Reports of weak sidewalls leading to premature damage
  • High cost relative to longevity when durability issues arise
All owner themes in the SP Sport 01 AS review

Tire B Primacy 4+

Pros

  • Strong wet and dry grip and braking confidence, often cited as a big improvement over Bridgestone, Dunlop and Nexen tyres, including on powerful cars and PHEVs that previously spun their tyres
  • Comfortable, compliant ride with soft sidewalls that suits softly sprung and family cars
  • Low and even tread wear, with several owners reporting little visible wear after 5,000–10,000 miles and one reporting about 60,000 km in hot climates

Cons

  • Road noise and drone, especially on rough asphalt, was described as severe by several owners (Skoda Yeti, Lexus), contradicting other reports of quiet running
  • Reduced grip and confidence in cold, damp conditions, with two UK owners saying the tyre behaves like a budget tyre
  • Premium pricing, with some owners questioning value when life fell short of expectations

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.
