Bridgestone Potenza Sport vs Pirelli P Zero PZ4

This head-to-head pits two flagship max-performance summer tyres against each other: Bridgestone's Potenza Sport and Pirelli's P Zero PZ4. Across 12 shared professional tests from 2021-2025 in popular 18-19 inch fitments, both target dry precision and wet security for performance road cars, but they take different paths to get there.

The Potenza Sport consistently delivers class-leading grip and lap-time pace, especially in the wet, while the PZ4 leans into refinement and efficiency. Recent tests amplify the split: Bridgestone dominates objective braking and handling (including a 1/52 overall in a 2025 shootout), whereas Pirelli scores for noise and rolling resistance, and can feel more polished day to day. Cost per kilometre and wear also separate them more than headline lap times suggest.

Test Results

Independent comparison tyre tests are the best source of data to get tyre information from, and the good news is there have been twelve tests which compare both tyres directly!

While it might look like the Bridgestone Potenza Sport is better than the Pirelli P Zero PZ4 purely based on the higher number of test wins, tyres are very complicated objects which means where one tyre is better than the other can be more important in real world use.

Let's look at how the two tyres compare across multiple tyre test categories.

Key Strengths

  • Outstanding wet and dry handling pace; dominant in 10/10 dry handling and 8/10 wet handling wins
  • Consistently shorter braking, especially wet (e.g., 27.6 m vs 32.3 m; ~15% better in 2025 shootout)
  • Strong aquaplaning resistance and wet circle performance across sizes
  • Superior value and wear in costed tests (e.g., +63% mileage; nearly half the €/1000 km vs PZ4 in 2025 Auto Bild)
  • Low noise and better refinement; frequent winner in noise tests
  • Lower rolling resistance in most tests, aiding fuel economy
  • Balanced, precise steering feel; strong subjective scores in select tests/sizes
  • Competitive dry braking and handling in warmer/drier conditions

Dry Braking

Looking at data from eleven tyre tests, the Bridgestone Potenza Sport was better during seven dry braking tests. On average the Bridgestone Potenza Sport stopped the vehicle in 1.47% less distance than the Pirelli P Zero PZ4.

Real World Driver Reviews

Bridgestone Potenza Sport Driver Reviews

Across 115 reviews, the Bridgestone Potenza Sport is praised for exceptional dry and wet grip, sharp steering response, strong braking, and confidence-inspiring handling, often rivaling or beating PS4/PS4S and PZ4. Many note it performs best when warmed and can be superb for spirited road use, with some citing good value. The most common drawbacks are rapid tread wear, higher noise and a firm ride, noticeable grip drop when cold, and poor durability on track abuse; a few also report slightly higher fuel consumption. Overall sentiment is strongly positive for performance-focused drivers, with caveats on longevity and comfort.

Based on 120 reviews with an average rating of 80%

Pirelli P Zero PZ4 Driver Reviews

Drivers generally describe the Pirelli P Zero PZ4 as a sporty, high-grip summer tyre with excellent dry performance, sharp steering response, and strong braking/feedback when warm. Wet grip is often rated good in light rain or when up to temperature, but many report reduced confidence in cold conditions and a notable weakness in standing water/aquaplaning, especially as tread depth drops. A frequent theme is fast wear and a performance drop-off (more noise and less wet security) as the tyre wears, making running costs feel high for some owners.

Based on 85 reviews with an average rating of 74%

Conclusion

Patterns across multiple tests are clear: if you prioritise outright performance and safety margins in changeable conditions, the Potenza Sport is the stronger, more confidence-inspiring choice. It repeatedly stops shorter (e.g., −14-15% in wet braking vs PZ4 in 2025 tests), turns quicker, and resists aquaplaning better, while also offering markedly better value and projected mileage in costed studies.

The PZ4 remains appealing for drivers who value cabin refinement, lighter steering/rolling feel, and efficiency. It is often quieter and easier on fuel, with competitive dry balance and strong subjective feel in some sizes, but it trails Bridgestone in critical wet metrics and long-term economy. In short: choose Bridgestone for maximum pace and wet-grip safety; choose Pirelli for lower noise/consumption and a smoother daily drive.
Key Differences
  • Wet braking: Potenza Sport repeatedly stops shorter (often 5-15% advantage in 2023-2025).
  • Handling pace: Bridgestone leads most dry and wet handling laps; Pirelli competitive but less often fastest.
  • Aquaplaning: Bridgestone generally better in straight and curved tests; Pirelli occasionally matches on curved.
  • Efficiency/refinement: PZ4 usually quieter with lower rolling resistance; Potenza rides firmer and louder.
  • Economy over time: Potenza Sport shows significantly longer wear life and lower cost per 1000 km in costed studies.
  • Price/positioning: PZ4 often pricier at purchase; Bridgestone tends to offer stronger price-performance overall.

Footnote

This page has been developed using tyre industry testing best practices. This means we are only comparing tests which have had both tyres in the same test.

Why is this important? Tyre testing is heavily affected by things like surface grip levels and surface temperature, which means you can only compare values from the same day. During a tyre test external condition changes are calculated into the overall results, but it is not possible to calculate this between tyre tests performed on different days or at different locations.

As a result you will see other tests on Tyre Reviews which feature both the %s and %s, but as they weren't conducted on the same day, the results are not comparable.

Lots of other websites do this sort of tyre comparison, Tyre Reviews doesn't.
