Comparison: BFGoodrich G-FORCE WINTER 2 vs. Semperit Speed-Grip 5 (2026)

Wet braking is genuinely even: across two directly comparable measured tests, both tyres averaged exactly 36.4m — as close as it gets. The individual results tell a nuanced story: the Semperit stopped slightly shorter in the 2024 test (36.8m vs 37.5m for the BFG), while the BFG edged ahead in 2023 (35.2m vs 35.9m). What separates them more clearly is aquaplaning resistance — the BFG holds a meaningful advantage here, which backs up its stronger aquaplaning scores and consistent tester praise for its wet reserves. The Semperit's wet handling on the other hand receives genuine praise from ADAC for precise, safe behaviour on wet roads, but lateral grip in wet cornering is a noted weakness across multiple test seasons.

Neither tyre is a dry-road star, but the BFG holds a modest edge on dry braking — testers across multiple programmes note slightly longer stopping distances for the Semperit, and the BFG's dry braking score (72) comfortably leads the Semperit's (59). That said, the Semperit shows better composure in dry cornering and handling, posting strong dry-handling averages in independent tests. The BFG has its own occasional criticism here — dry ride comfort suffers from a stiffer feel — but its limit behaviour is described as secure and predictable. Neither would be your first choice for a sporty dry-road experience, but both handle everyday winter driving conditions safely.

This is where the BFG G-FORCE WINTER 2 makes its most compelling case. Its snow score of 93.2 towers over the Semperit's 75, and the braking data supports this: across two measured snow braking tests, the BFG averaged 29.4m versus 30.2m for the Semperit — a consistent advantage that widens in more demanding conditions. In the 2023 test, the gap reached two metres (29.3m vs 31.3m), which is significant on compacted snow. Testers have called the BFG a snow champion outright, with top-tier scores in snow handling, traction, and circle cornering. The Semperit is competent on winter surfaces and praised for its winter-road safety, but its lateral grip on snow is a recurring limitation, and it lacks the BFG's outright snow mastery. Drivers regularly encountering serious snowfall should take note of this gap.

Both tyres are reasonably quiet, with real owners highlighting this for both — but the BFG edges the exterior noise tests (82.6 vs 77.0 in measured averages), and ADAC 2025 flagged the Semperit for louder rolling noise, which is the more significant finding. Where the Semperit pulls ahead decisively is rolling resistance: at 83, it leads the BFG's 73.1 by a meaningful margin, translating into lower fuel costs over time. The BFG's predecessor-free lineage means there's no history of improvement to reference, but its current mileage scores are respectable. The Semperit, successor to the Speed-Grip 3, has built on that model's efficiency credentials and ADAC measured very low wear — though our overall mileage scoring reflects some variability across tests.
