4 SIDEWALL PENETRATION
This is one of the most important tests in our shootout. We’re proud of the fact that no other local publication has ever done a similar test. A few years ago we had a special machine built that could measure the pressure (in kPa) it requires to penetrate something. We believe a tyre’s ability to resist sharp objects is one of its most important characteristics – much more important than tar road handling and tyre life span – if you really want to go off-road. As expected the BF Goodrich T/A stood out from the rest. Similarly we also expected that the Continental CrossContact AT wouldn’t perform well. From personal experience its grip is good but their sidewalls are vulnerable to sharp objects. It remains a good tyre for tar road but we suspect it was designed as a 90:10 tar and dirt road tyre. The big surprise, however, was just how good the Goodyear Adventure did.
TAKING A STAB. With a lot of the results being quite similar for a lot of tyres, we knew that the dreaded shoulder-puncture test was going to end up making a huge difference in the final score, which it undoubtedly did.
