Comparison: Bridgestone Blizzak LM-005 vs. Semperit Speed-Grip 5 vs. GoodYear UltraGrip Performance 3 vs. Michelin PILOT ALPIN 5

This is where the Blizzak makes its case with hard numbers. In the Autobild 2023 braking shootout across 54 winter tyres on 225/45 R18, the Blizzak recorded a wet braking distance of 31.4 m against the Speed-Grip 5's 35.9 m — a 4.5-metre gap that is enormous in real-world emergency stops, and enough to put the Blizzak first overall and the Speed-Grip 5 nineteenth. Its wet-handling objective score of 99.3 and wet-braking score of 94.6 reflect a tyre engineered specifically around aquaplaning prevention and wet grip. The Speed-Grip 5 is not dangerous in the wet — testers describe it as safe and precise on wet roads — but it carries a clear wet-performance deficit versus premium competition, and its EU wet-grip label (C) versus the Blizzak's predominantly A-rated wet grip tells the same story. For drivers who regularly encounter heavy autumn and winter rain, the Blizzak's wet advantage is its defining argument.

Neither tyre is a dry-road hero, but the gap between them is real. The Blizzak's soft, wet-optimised compound pays a well-documented penalty in dry braking, and testers consistently flag it as the tyre's headline weakness. The Speed-Grip 5 is also criticised for extended dry stopping distances, yet its dry-braking score in aggregated test data edges ahead of the Blizzak. In everyday winter use — cold but dry tarmac — the difference is unlikely to alarm most drivers, but spirited or motorway-speed drivers should factor in that neither offers the reassurance of a premium summer or all-season tyre on dry roads.

Snow is where the gap closes dramatically. In the same Autobild 2023 test, snow braking distances were almost identical: 30.9 m for the Blizzak versus 31.3 m for the Speed-Grip 5 — statistically a dead heat. The Blizzak is quick and agile in snow, but testers repeatedly note a tendency toward understeer and modest lateral grip on snow surfaces, limiting its overall winter score. The Speed-Grip 5, meanwhile, earns consistent praise for safe and precise winter handling across multiple ADAC test cycles, and its snow-handling score of 78.8 actually edges the Blizzak. For drivers primarily concerned with snowy conditions — mountain roads, heavy snowfall regions — the Speed-Grip 5 punches well above its price point and offers genuinely comparable capability to its premium rival.

Both tyres deliver similar ride comfort in the low 80s, and neither stands out as particularly harsh or particularly cosseting. The Blizzak's heavier construction has been flagged by testers, while the Speed-Grip 5's lighter weight contributes to slightly lower rolling noise in some tests — though ADAC 2025 noted louder exterior noise as a minus. Where the Speed-Grip 5 pulls ahead meaningfully is running costs: testers consistently award it top marks for rolling resistance and low wear, and real owners on review platforms echo this, citing good value and low running costs with no significant complaints logged. The Blizzak's mileage score is a known weak point — its soft compound grips supremely but wears faster, making the lifetime cost higher than its purchase price suggests.
