Take for example wet braking. To get the wet braking distance of a tyre, you don't just do the braking run once, you do it 6-8 times, delete the outliers then average out the results. Even on the most expensive test facilities in the world, with the most perfect sprinkler systems and perfect tarmac, you rarely get the same distance twice as there are so many variables, which means when you use a less than state of the art facility, results can be surprising.
This brings us on to this test by the Italian publication "al volante".
On the surface, this should be a very interesting test, as it includes the new Goodyear EfficientGrip Performance 2 and the new Pirelli Cinturato P7 C2, but after initial inspection, the test seemed of limited use.
Firstly, we've never seen such a big advantage in wet braking by a single tyre as this test, and having spoken to Continental they're unsure of why it was so large. Secondly, while the Ultrac Satin has never been the best dry braking tyre, 8 meters difference from just 100 KM/H is almost unheard of. Thirdly, the testers indicate in their writing that dry handling was conducted, but no times were given, and lastly with a 25% difference in wet braking, I would have expected much more than a 2% difference in wet handling, especially over a 100 second lap!
Having spoken to a number of tyre manufacturers in this test, it seems the test wasn't conducted at a permanent facility, but a temporary one, which could explain the interesting results below.
In short, this is another piece of information to help you select the best tyres for your vehicle, but perhaps it's best not to read into this test too much. Make sure to browse all the other tests available on Tyre Reviews.
