Comparison: Nokian Powerproof vs. Uniroyal RainSport 5 (2026)

This is where the Nokian Powerproof pulls clear. In their one shared test — Autobild 2022 — the Powerproof finished 6th overall against 51 tyres, posting 35.7 m on dry asphalt, while the RainSport 5 trailed at 36th with 38.4 m. That 2.7-metre gap is meaningful in real-world emergency situations. The Powerproof's dry braking score of 87.8 versus the RainSport 5's 72.3 tells the broader story: across all dry braking evaluations, this gap is consistent. In handling terms, the Nokian rewards a more committed driving style — spontaneous turn-in, precise steering feel, and lateral composure that owners of performance cars like the Megane RS have found genuinely confidence-inspiring. Its one acknowledged weakness is a tendency toward delayed initial turn-in at the very limit, and some instability under maximum cornering loads. The RainSport 5, by contrast, is frankly soft on dry roads: testers consistently flag vague lateral support and slow steering response on dry circuits, and its lap times on dry tracks place it at a clear disadvantage against any sporty competitor.

On wet roads, the picture is more nuanced. The Powerproof remains a strong performer — 28.9 m wet braking in the Autobild test, a genuinely competitive result. Its wet handling character is neutral to mildly understeering, progressive and predictable, which suits both confident and cautious drivers. Where it loses ground is aquaplaning resistance, a recurring weakness in test evaluations: its longitudinal aquaplaning score of 80.7 is solid, but the overall aquaplaning score of 76.2 points to vulnerability in lateral situations at speed. The RainSport 5 exists in a different league here. Its aquaplaning scores — 90.9 longitudinal, 92.8 crosswind — are among the best in its class, built around Uniroyal's Shark Skin Technology and Aqua-Twist Sipes, which evacuate water with exceptional efficiency. Wet braking is closely matched at 80.5 vs 79.4, but the RainSport 5's overall wet confidence is higher, particularly in standing water. An owner who drove one at Oulton Park in storm conditions reported being genuinely surprised by how much grip remained available in what they described as horrendous conditions — real-world evidence that matches the test data well.

The RainSport 5 is the more refined daily companion. It scores 81.2 for both comfort and noise — noticeably ahead of the Powerproof's 75.5 and 74.7 respectively — and in the Netzwelt 2026 test it took best-in-test for rolling comfort and lowest exterior noise. Owners consistently praise its refinement, and it fits a broader range of vehicles from R15 to R21 across 101 sizes. The Powerproof generates a mild singing tone at certain speeds and offers less cushioning over poor surfaces — not harsh, but noticeably busier. Mileage is another point of difference: the RainSport 5 scores 61.6 for longevity against the Powerproof's 53.7, which aligns with real-owner reports of the Nokian wearing noticeably faster. Both tyres carry a C fuel efficiency rating, so running costs from rolling resistance are broadly comparable.
