Pros, cons & observations

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

Tire A Sport Maxx 050+

Pros

  • Strong dry grip, precise steering response and confident high-speed cornering, with several owners saying they could not find the tire's limit
  • Good value: reviewers report performance comparable to Continental or Pirelli P Zero tires at a notably lower price
  • Generally good to very good tread life, with reports of about 40,000 to 50,000+ km

Cons

  • Road noise is the most common complaint, with several reviewers calling the tire very loud, especially on concrete highways
  • Harsh, stiff ride quality, including thumps over bumps and potholes
  • Inconsistent wet performance: multiple reviewers report slipperiness, reduced confidence in rain and aquaplaning

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.
