The 2020 Auto Bild AllRad SUV / 4x4 tire test has looked at the popular 255/55 R18 tire size. While the tire patterns included in the test are aimed at "soft roaders", which spend 99% of their time on normal roads, Auto Bild still went to the effort of testing the handling and traction on gravel of all ten tires, along with traction on grass, mud and even sand!
Off-road performance is often an opposing quality to on-road grip, with dedicated off-road tires performing well in loose surfaces such as gravel and mud, but poorly on-road in the dry and wet. It's worth noting, as we found out with our off-road tire test, repeatable off-road testing is extremely difficult, especially in mud, so these figures should only be used as a broad guide.
Dry
Dry braking is often closely contested, but the new Michelin Pilot Sport 4 SUV proved to have a near meter advantage over the nearest rival. It's also been a long time since we've seen a budget tire perform poorly in the dry, which is exactly what the Lexani LX-Thirty did, stopping the SUV 6.5 meters behind the Michelin!

Like dry braking, wet braking saw Michelin and Dunlop leading the way, with the budget Lexani tire taking over 20 meters longer to stop the vehicle.

Offroad
Off-road is where things get really interesting / confusing. Usually, a tire that performs well off-road, doesn't perform on-road, but it seems Michelin have done their best to disprove that rule.
The Pilot Sport 4 SUV was the best in the wet and dry overall, and had the fastest lap time during gravel handling.

And finally it will be no surprise that the Michelin was the most expensive set of tires on test, and the budget the cheapest! No wear testing was performed this time, so we're unable to work out what value each tire represents.
