Pirelli P ZERO 255/40R21 102Y Ultra High Performance Summer Tires PZERO UHP P2181400 / 255/40/21 / 2554021

The Pirelli P Zero (R01) is a high-performance summer tire manufactured for passenger vehicles. It is the original equipment tire for select Audi Quattro vehicle models. The tire has superb summer weather traction. Its silica-based tire compound provides excellent road gripping ability in wet and dry weather. The model is not meant to be used in winter weather as the decreased traction in cold temperatures makes it dangerous to use in such weather. The wide circumferential grooves enhance the water dispersing ability and avoid hydroplaning to ensure safer wet weather traction. The asymmetric tread pattern helps lower the road noise heard in the vehicle’s cabin. The inner tread area features a variable pitch sequence that generates sound waves to negate the road noise heard while the tires are in motion. The outer tread area’s low noise emission lowers the road noise levels created to lessen the discomfort caused by the road noise. The combination of these two elements improves the driving experience and make it quiet and comfortable. The customized tire compound eases the driving pressure off the tire, which reduces the rolling resistance. This in turn decreases the vehicle’s CO2 emissions and fuel usage per mile, making the tire more fuel and cost efficient. The same tire compound also slows down the tread wear rate, offering longevity and extended usability. The P Zero (R01)’s outside shoulder tread block sequence enhances its road gripping ability. The additional road grip and biting edges provided by the tread elements enhance the cornering ability and power. The better cornering and maneuvering capability ensure a secure drive in all summer weather. Built with three solid central ribs that increase braking and traction when driving at higher speeds Features a stiff, optimized contact patch that further boosts traction and reduces uneven wear for a longer tread life The structure of the tire aims to provide great steering response, which is essential in sports driving, and is designed to achieve uniform treadwear PNCS (Pirelli Noise Cancelling System) and the special-shaped grooves in the tread area are designed to reduce internal noise and to enhance drive’s comfort This product features Run-Flat technology, which is designed to allow drivers to maintain better control and drive up to 50 miles under certain conditions in the event of a rapid loss of inflation pressure Size: 255/40R21 Load Range: XL Product May Vary From Picture Wheel/Rim Not Included Specifications Features Size 255/40R21, Season: Summer, Performance: High-Performance, Car Type: Truck/SUV, Load Range: XL Tire Size 255/40R21 Vehicle Type Car Tire Width 255 Wheel Diameter 21 Warranty Distance 0 miles Tire Season Summer Tire Speed Rating Y Tire Type Passenger Car Tires Tire Load Index 102 Uniform Tire Quality Grade (UTQG) 300 AA A Tire Traction Rating AA Tire Treadwear Rating 220 Tread Depth 10/32 Brand Pirelli Assembled Product Weight 30.24 lb Model P Zero Manufacturer Part Number 2181400 Manufacturer Pirelli Assembled Product Dimensions (L x W x H) 29.02 x 10.24 x 29.02 Inches
