2018 Wheels Tyre Test: Wet cornering

2018 Wheels Tyre Test: Wet cornering

Upping your car’s cornering G-force by 10 percent is the stuff of a sports suspension upgrade, right? And cutting a car-length from your braking distance is the work of a set of Brembos? Nope, you just need a great set of tyres

Even more so than the wet braking discipline, Wet Cornering proved a definitive differentiator between the greats and not-so-greats of the group. Measured by entering a consistently soaked double-apex left-hander at 60km/h, the Commodore revving hard in third gear, Renato would squeeze on power and build G-force during the first part of the corner before truly testing the wet threshold at the slippery second apex.

While the Momo achieved a higher limit than the Hifly and Vitora bottom-enders, it compounded a below-par wet braking performance by giving up when push came to shove. “At 0.92G it was fine and controllable; at 0.93G it massively understeered,” commented our testing ace. The GT Radial clearly telegraphed its limit of grip (with a 0.95G average), however “the transition from max grip to slip is a very small window,” said Renato.

In contrast, the last-placed Vitora offered “good slide warning on the limit”, however its limit was well below what the exercise-winning Falken could achieve.

RESULTS

Falken Azenis FK510 - Winner

Only three tyres managed 1G or greater in the wet-cornering exercise and, once again, the Falken proved its worth in challenging conditions. With the highest peak G (1.020, on its first and last runs) and an overall average of 1.007G, the Falken underscored why it’s such a superlative all-rounder – “incredible grip in wet cornering; almost no sliding at all doing 73km/h” commented Renato, even though it only needed to complete the exercise at 60km/h. Renato could keep adding power and the star wet-cornering tyres – Falken, Continental, Maxxis, and Hankook – could cop the greater load before transitioning predictably into the inevitable front tyre slip.

 

THE TYRE TESTS

The swerve-and-recover test, or slalom – just like the skiing event – is an efficient way to gather meaningful data on a tyre’s transient grip level in less than 10 seconds.

You would've thought that simply jamming on the picks as hard as you can and letting the anti-lock braking system (ABS) sort out the rest was a given in a modern car. And it is, but not without one big variable – tyres.

It’s the one discipline that separates the mighty from the mediocre by a big margin … and we’re talking about brand new, correctly inflated, high-spec tyres here!

Few surfaces in the world can match the noise generation of an Australian coarse-chip road, so tyre noise does play a vital part in the driving performance of your vehicle.
