Comparison: Barum Polaris 3 vs. Uniroyal MS plus 77 (2026)

Flip to wet weather and the picture shifts significantly in Uniroyal's favour. Across four measured wet braking tests, the MS plus 77 averages 38.2 metres to the Barum's 37.6 metres — so the gap is narrow and the Barum is actually slightly shorter on average, but the Uniroyal's advantage lies elsewhere: aquaplaning. Its aquaplaning score of 80.8 dwarfs the Polaris 3's 68, meaning on standing water at motorway speeds the Uniroyal offers considerably more margin before the tyre loses contact. Wet handling scores tell the same story — 77.2 versus 73.6. Customer reviews of the MS plus 77 are dominated by praise for wet road performance, mentioned eight times, suggesting drivers genuinely feel the difference in real conditions. The Barum's wet braking score is reasonable at 84, but that aquaplaning weakness is a real limitation on flooded roads.

On dry tarmac, the Barum holds a genuine edge. Its overall dry score of 79 outpaces the Uniroyal's 74.4, and in the head-to-head tests across multiple AutoBild seasons, the Polaris 3 more consistently placed ahead in overall ranking when dry conditions were weighted. Real-world owners back this up — one driver running the Barum on a tuned 400hp BMW noted that dry grip was almost on the same level as wet grip, a remarkable finding for a budget winter tyre. The Uniroyal is no disaster on dry roads, but testers repeatedly flagged its handling as less inspiring under those conditions, and the data reflects it.

Snow is where the Barum Polaris 3 reasserts itself. Its snow score of 87.3 is meaningfully ahead of the Uniroyal's 81.3, and the braking numbers across four snow tests are essentially identical — 27.5 metres versus 27.6 metres — so the difference is more about traction and handling confidence than pure stopping power. Barum's own description of the Polaris 3 emphasises optimised snow setting-off and braking, and the test data supports it: in the 2015 AutoBild test the Polaris 3 finished an impressive 3rd overall, while the MS plus 77 languished in 15th. Uniroyal's detailed scores show decent snow-handling (80) and snow-braking (83.8), but the Barum simply feels more planted and predictable in deeper snow conditions — a quality that real owners consistently report.

The Barum Polaris 3 is the quieter, more comfortable tyre of the two. Its comfort score of 79 versus the Uniroyal's 73.1, and noise score of 79 versus 72.6, are consistent with what owners report — quietness was specifically called out positively eight times in customer feedback. The Uniroyal drew mild criticism for noise from some drivers, and its comfort score reflects a tyre tuned more for grip than refinement. Rolling resistance is similar for both, with the Barum scoring marginally better at 84 versus 82, though a couple of Uniroyal owners noted slightly increased fuel consumption. Expected mileage is broadly similar and modest for both — winter compound softness takes its toll on longevity regardless of brand.
