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
59/100From 1 owner review analysed, scaled like the road tests: the average tested tire gets 70.
By road tests
73/100Scaled across every tested tire: the average gets 70, the best 100.
What owners like and dislike
Themes extracted from 1 owner review found online.
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.
Pros
- Exceptional grip and traction on snow
- Impressive performance on icy surfaces
- High value-for-money proposition
Cons
- Poor wet road handling and braking performance
- Mediocre dry road stability
- Prone to slipping in wet conditions
Worth knowing
- Users with low-horsepower compact vehicles, such as the Renault Clio 0.9 TCe, report that the tire's wet-weather deficiencies are noticeable even under light acceleration.
