Data updated
Which should you buy?
Choose the Michelin Primacy 5 if you want a refined, quiet, low-rolling-resistance touring tire with strong aquaplaning safety for heavy-rain motorway use. Choose the Kleber Dynaxer HP5 if your priority is maximum day-to-day grip security-especially braking and wet cornering-at a likely better price, and you can accept higher noise and slightly weaker hydroplaning margins.
Where the Dynaxer HP5 is stronger
- Consistently shorter braking distances in both dry and wet (wins 2/2 in each)
- Stronger lateral wet grip (wet circle wins 2/2), supporting confident cornering on damp roads
- Very even, predictable all-round balance with no major weaknesses noted by testers
Where the Primacy 5 is stronger
- Clearly stronger aquaplaning resistance in both straight and curved tests (wins 2/2 for each)
- Lower rolling resistance (about 9% advantage), supporting better fuel economy/EV range
- Quieter on the road (about 1.5-1.9 dB lower in the shared tests) with a comfortable touring bias

In each test the better of the two figures counts as 100% and the other as its share of it, so a 118 ft stop against 112 ft is 95%; each spoke averages the shared tests that recorded it. The scale stops at 96%: a point further in sits on the hub's edge, hollow. 3 measurements recorded in only one shared test are left off; every measurement is in the table further down.

Braking distances and lap times are better when lower; speeds, wear and grip figures when higher. A test's figures are its own: sizes, cars, surfaces and temperatures differ from one to the next, which is why the averages here are only ever of tests the two tires shared. "Scored" rows are subjective driver ratings: each test uses its own scale, so only the wins are counted.

Kleber Dynaxer HP5

- 5,800 milesdriven by reviewers
Drivers report the Kleber Dynaxer HP5 tire delivers strong overall performance, with frequent praise for quiet running, a soft/comfortable ride, and confident grip-especially in wet conditions. Most high-scoring reviews describe stable, safe handling and good value for money. One lower-scoring review notes noticeably softer sidewalls leading to imprecise high-speed response compared with Goodyear Asymmetric 6, suggesting handling sharpness may not satisfy drivers wanting a firmer, sportier feel.
- Quiet/low road noise
- Comfortable, soft ride and good bump absorption
- Good grip and confident handling (notably in wet)
- Good value for money

Michelin Primacy 5

- 378,963 milesdriven by reviewers
Owners generally rate the Michelin Primacy 5 highly (82% average), most often praising its notably comfortable, refined ride and strong wet-weather confidence. Around three quarters of reviewers mention noise, and while many find it very quiet, a sizeable minority report intrusive droning on certain road surfaces. Grip and efficiency are commonly highlighted as strengths (especially in the wet and for rolling resistance), but around one in five owners feel it sacrifices dry handling and steering precision compared with sportier alternatives.
- Very comfortable, smooth ride quality
- Low road noise for a touring tire (especially at speed)
- Strong wet grip and reassuring wet traction
- Low rolling resistance / good efficiency
- Can be noisy or drone on rougher road surfaces
- Soft, less confident dry handling in corners
- Less direct steering feel / reduced precision
Summarised by AI from 62 vetted reviews; the reviews themselves are on the tire page.
All 62 Primacy 5 reviewsThe tires are very silent and comfortable. Despite this they are very grippy in the dry and wet and give a good feedback. Driven in 40+ degrees in summer until now in rainy 5 degrees autumn and they make the drive 100% secure.

Reading the results
Written from the test results and owner reviews above. It is analysis, not a measurement: where it and the tables disagree, the tables are right.
Kleber's Dynaxer HP5 and Michelin's Primacy 5 sit in the same “premium-touring summer” brief for everyday passenger cars, but the two tires chase that goal in noticeably different ways. Across two independent 2026 tests in the popular 225/45 R17 size, the Kleber repeatedly focuses on grip-based safety metrics (especially braking and lateral wet grip), while the Michelin leans harder into refined road manners and efficiency.
What makes this head-to-head interesting is that Michelin is the higher-priced premium benchmark brand, yet in both shared tests the Primacy 5 only finishes mid-pack overall (5/9 and 6/13). Meanwhile the Kleber, often positioned as the value choice within the Michelin group ecosystem, lands just behind it overall (7/9 and 7/13) and actually beats it in several key objective grip measurements-while losing clearly on aquaplaning resistance, noise and rolling resistance.
Conclusion
On pure “stop and turn” grip in typical wet and dry conditions, the Kleber Dynaxer HP5 is consistently the sharper tool in these two tests. It beats the Primacy 5 in dry braking twice (38.0 m vs 38.4 m; 37.98 m vs 38.39 m) and also in wet braking twice (45.5 m vs 46.5 m; 29.12 m vs 29.73 m). It further shows stronger lateral wet grip via wet circle in both tests, suggesting more confidence when the road is damp and you're loading the tire through longer corners.
The Michelin Primacy 5's wins are concentrated where “touring” tires earn their reputation: it is quieter (by ~1.5-1.9 dB in these tests), more energy-efficient (rolling resistance advantage ~9%), and markedly better in aquaplaning (about +4.9% straight-line and +3.6% curved in both test datasets). Subjectively, drivers also rated the Michelin better on dry handling feel, and both tires matched on comfort scoring in the provided results. The practical takeaway: if your priorities are low noise, fuel/EV efficiency and strong hydroplaning security on waterlogged motorways, the Primacy 5 fits the brief; if you want stronger braking and wet cornering grip for mixed roads and frequent stop/turn scenarios-especially at a competitive price-the Dynaxer HP5 is the better-value “safety grip” pick, even if it gives up refinement and aquaplaning headroom.

Where this data comes from
Finishing positions and measurements are transcribed from each published test. A test only counts here when both tires ran in it, so every figure was recorded on the same car, size and day as the one it is compared to.
About the TR Score
The Tire Reviews Score rates each tire out of 10 from every independent test result and vetted owner review we hold, so two tires can be compared even before a test has run them together.
Who does the testing
Every test published as a Tire Reviews test is run by Jonathan Benson, who has been testing tires independently since 2007.
