While the slalom and brake test elements are designed to isolate a tyre’s cornering and braking talent, the handling circuit instead puts every aspect of tyre ability together as a compact way of measuring a tyre’s handling and collision-avoidance capability. The fact that it’s a bit of fun certainly doesn’t hurt driver morale considering the repetitious, analytical nature of the rest of the program. A lap starts with an open right hand sweeper, which feeds into right and left hairpins, followed by a short straight. Then there’s a 90-degree right-hander, a left/right chicane, and the start/finish line. We use the circuit to scrub the surface of each new set of tyres too, and it’s startling to see how much grip improves after a handful of laps. Every element from transient and steady cornering to braking is tested, and tyre temperature is added to the equation, the left front copping the worst of it over our trio of two-lap dashes. Time is the measure of performance on the circuit and we record lateral G-force, too. The median two-lap time was 56.73 seconds, with the best and worst times separated by 1.85sec. We saw more than 1.0G a couple of times, against a median of 0.94.
