The Petlas Glacier W661 is regarded as a budget-friendly winter tire that excels in severe snow and ice conditions, often rivaling premium competitors in traction. However, its performance on wet surfaces is significantly lacking, with users reporting a notable tendency for slippage even in low-horsepower vehicles.
Owners rate it 14.9 points lower than the instrumented road tests do — see the two score breakdowns below for where they disagree.
Two scoring systems, side by side
Owner scores come from reviews found online; road-test scores come from instrumented tests. Where they disagree, it is usually a discipline owners rarely push to the limit.
How scores work
- Relative score
- 0–100. Blends road tests (60%) and owner reviews (40%) category by category, the same way on every TireWheelGuide page. With only one of the two, the missing half is estimated from it, so the score stays closer to average. It needs at least one road test or five owner reviews.
- Road tests
- 0–100 per score, from published tests, newer tests counting more. Each result is compared with every other tire in the same test, so a win against a strong field counts for more. The average tested tire gets 70, the best 100; with only one or two tests a tire stays nearer 70. The discipline rows show % of the best tire in that test.
- Owner reviews
- 0–100 from the owner reviews we found online, adjusted for how generously each site rates and scaled like the road tests: the average tested tire gets 70. With only a few reviews a tire stays near the average.
By owner reviews
58/100From 1 owner review analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
