By 1915, absinthe had been banned in the United States and in much of Europe, including France, the Netherlands, Belgium, Switzerland and Austria-Hungary. Although absinthe was vilified, it has not been demonstrated to be any more dangerous than ordinary spirits.
During one of our recent performance rating tests on hard braking in an emergency situation, a lower âSâ rated tire driving 100 kilometres per hour was still going almost 25 km/hr when the higher âVâ rated tire stopped. The âSâ rated tire took 39 metres to stop. The âVâ rated tire stopped in 35 metres.
Z-speed rated tires. Where have they gone? No worries; they're still here. â¦they're not Z-speed rated? What's the deal here? Back in the day, high performance tires were all Z-speed rated. They were tested at some speed above 149 mph. In order to be more precise, tire manufacturers started testing at 168 mph (W-speed rating) and 186 mph (Y-speed rating).
