PZero Nero's slogan is "works harder, plays harder", derived from the tire's two major characteristics: Driving Force The Extra Load capacity assists in maintaining the performance of both sports saloons with full equipment options and increasingly heavy and powerful tuned cars. New technology ensures a higher load carrying capacity without compromising driving comfort Driving Enjoyment The comprehensive range extends the limits of driving pleasure. No compromise in dry and wet handling and, in powerful ABS braking, with significantly reduced stopping distances. These features not only make the PZero Nero the ideal choice for tire/wheel conversions but add a new dimension to the car that reflects the drivers individuality. Tread pattern: Asymmetric Ultra High Performance tread design with variable angle grooves to minimize aquaplaning and optimized pitch for acoustic comfort.
The load rating (represented by the numerical value) is related to the maximum weight that tyre can carry. So in this case 105 would refer to a load capacity of 925kg, with most passenger vehicle load indexes range from 62 to 126.
In all instances the tyres load index must meet or exceed the value displayed on the vehicles placard.
The speed category symbol, for example 'S', indicates the maximum speed at which the tyre can carry a load corresponding to its load index. So in this case, 'S' would refer to a maximum speed of 180km/hour.
