The calculation on this page does not use these results: our check showed that a test in another size does not predict wet braking better than the EU label for your size. They are shown here as measured facts.

Frequently asked questions
What is the wet grip class of the Imperial Snowdragon UHP?
On the EU tyre label, the Imperial Snowdragon UHP has wet grip class C in every size in our database. A is the best and E the worst. The difference between class A and class E is about 18 m of braking distance from 90 km/h on a wet road.
How long is the braking distance of the Imperial Snowdragon UHP on a wet road?
According to the Pidurdusmaa.ee calculation, the Imperial Snowdragon UHP 215/55 R17 stops from 90 km/h on a wet road in about 48 metres (Volkswagen T-Roc II (2025+), without reaction time). The calculation is based on an independent test.
Is the Imperial Snowdragon UHP suitable for an Estonian winter?
Better suited to milder winters. The Imperial Snowdragon UHP is a Central European winter tyre made for wet and slushy roads. On ice and snow it needs a longer braking distance than a Nordic friction or studded tyre.
How long is the braking distance of the Imperial Snowdragon UHP on ice?
Based on an independent test, the Imperial Snowdragon UHP 215/55 R17 stops from 50 km/h on ice in about 124.9 metres (Volkswagen T-Roc II (2025+), without reaction time). Calculated by Pidurdusmaa.ee with the same model as the calculator. Use the calculator to see the result for your own car.
Has the Imperial Snowdragon UHP been independently tested?
Yes. Source: ADAC winter tyre test 2025. The Imperial Snowdragon UHP stopped on dry asphalt from 100 km/h in 44.6 m, ranking 20 of 31 tyres. All measured results are in the table above.
What sizes is the Imperial Snowdragon UHP available in?
In the EU tyre register, our database has the Imperial Snowdragon UHP in 61 sizes, for example 175/60 R16, 205/40 R18, 205/45 R17, 205/50 R17, 205/55 R17 and 205/55 R19. As a main factory size it fits cars such as the Audi A6 C9 (2025+), Audi Q3 III (2025+) and BMW iX3 NA5 (2025+).
