The AZ850 is a performance tire designed for the modern SUV, Cross Over and Sport Truck to take advantage of the increased power and handling ability of these vehicles.
The AZ850 asymmetric tread design features different inside and outside tire contours to achieve optimum balance across the tread face. This design evenly distributes the pressure of the contact surface to enhance comfort and handling.
The AZ850 is also available as a Run Flat model. The RFT sizes are engineered to allow for up to 50 miles of driving at 50 MPH (80km at 80 KPH) with zero air pressure. The Run Flat AZ850 offers an affordable option to the overpriced original equipment tires found on many performance SUV, such as the BMW X5, without compromising on performance or quality. The AZ850 RFT also offers an enhanced safety option to those drivers who are looking for the security of a run flat tire, even if it was not original on their vehicle.
The unique compound and tread design of the AZ850 were specifically engineered for the contemporary performance utility vehicle. The result is a rubber compound that helps reduce rolling resistance, which, in turn, allows the tire to run cooler at high speed. High-tensile steel belts and jointless nylon bands increase stability at high speeds and provide secure braking, handling and durability.
AZ850 Design Features:
The large outer tread block is designed with a rigid and strengthened block to maintain integrity under hard cornering.
The finely sliced inner tread block is designed to reduce noise and allow dispersion of water.
Four main grooves designed to increase the wet grip.
Center rib improves straight-line driving; Also enhancing directional stability.
Oblique lateral grooves increase water dispersion capacity in order to avoid .
EU Tyre Label and Efficiency Classes
The European Union, under CE 1222/2009, has mandated that all tyres manufactured after the date of July 1 2012 for cars and commercial vehicles include standard EU Tyre Labels classifying them by three performance characteristics:fuel efficiency classified from A to G,wet grip classified from A to G, and noise emission in decibels.
Categories of tyres unaffected by this regulation include: retreaded tyres, professional off-road tyres, racing/sports car tyres, as well as certain types of tyres designed to improve traction such as studded tyres, T-type temporary spare tyres, tyres for cars built before 1990, tyres with a maximum allowed speed of 80km/h, tyres for rims with a diameter less or equal to 254 mm or greater or equal to 635 mm.
This label is intended on one hand to promote economic and ecological efficiency in traffic, as well as increase road safety, and on the other hand to help consumers select appropriate tyres by ensuring a certain degree of product transparency.
Nevertheless, the label has been criticized for only showing a very limited number of characteristics. Professionals argue that tyres have many more features that are important and relevant to road safety, including but not limited to aquaplaning properties, driving stability, service life, product properties on wet and dry roads other than wet grip, properties on snow.
Tyre manufacturers suggest that the test results from various institutions and industry magazines should remain a very important source of information for the end consumer, because they focus on and rate a wide variety of tyre properties and features.
