Magazine tests
Published braking distances (Auto Bild, auto motor und sport, Auto Zeitung, ADAC, Za Rulem and others). Rank = position in the same test on the same surface (1 = shortest). The tests use different sizes, cars and conditions, so only compare numbers within the same test.

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 Radar Dimax R8+?
On the EU tyre label, the Radar Dimax R8+ has wet grip class A to B, depending on the size. 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 Radar Dimax R8+ on a wet road?
According to the Pidurdusmaa.ee calculation, the Radar Dimax R8+ 215/55 R17 stops from 90 km/h on a wet road in about 45 metres (Volkswagen T-Roc II (2025+), without reaction time). The calculation is based on wet grip class B on the EU tyre label.
Has the Radar Dimax R8+ been independently tested?
Yes. Source: Auto Bild 2025. The Radar Dimax R8+ stopped on wet asphalt from 80 km/h in 31.7 m, ranking 21 of 52 tyres.
What sizes is the Radar Dimax R8+ available in?
In the EU tyre register, our database has the Radar Dimax R8+ in 102 sizes, for example 205/40 R17, 205/40 R18, 205/45 R17, 205/50 R17, 215/40 R17 and 215/40 R18. As a main factory size it fits cars such as the BMW iX3 NA5 (2025+), BYD Seal 6 (2025+) and Chery Tiggo 8 (2025+).
