The Atturo AZ850 DR is a radial drag race tire that's designed for use on street cars. With four main channels and a solid center rib, the AZ850 DR provides better traction and stability, even on wet roads. In addition, AZ850 DR has large shoulder tread blocks to offer precise cornering, even at higher speeds.
Features & Benefits
- Drag race radial tire designed for use on street cars
- Four main channels with oblique lateral grooves remove water from footprint for enhanced wet grip
- Solid center rib with beveled sipes enhances straight-line stability and provides a quieter, more comfortable ride
- Finely sliced blocks inside the shoulder reduce noise and assist in hydroplaning resistance
- Large shoulder tread blocks provide precise cornering and predictable turning, even at higher speeds
Ultra High Performance (or UHP) tires have a speed rating of V or greater and are used on sports cars, super cars, and other powerful vehicles. Commonly featuring a wide footprint and low profile, UHP tires provide excellent traction and steering response but should not be used when temperatures are at 40 degrees or below.
Passenger tires are some of the most common tires you'll find on the roads today, and frequently used on coupes, sedans, hatchbacks, minivans, and other passenger vehicles. Passenger tires are available in a wide variety of types, such as all-season, winter, and ultra-high-performance.
This product is not covered by a manufacturer’s treadlife warranty.
The maximum carrying capacity for a tire determined by the manufacturer.
Maximum speed capability to safely carry a load for an extended period of time.
The maximum load carrying strength at the specified inflation pressure, also known as ply rating.
The side of the tire between the tread and rim, with cosmetic branding as well as information about the tire including manufacturer, model, size, etc.
Standards that measure treadwear, temperature resistance and traction, example: "640 A A". The 640 is the treadwear test and it lasted 6.4 times longer than the comparison tire tested against. The first "A" is the traction rating using straight-line wet traction on test surfaces (see information tables tab) and the second "A" is the temperature rating by testing operation at high speeds without heat-related failure (see information tables tab).
Wet Traction is a piece of the UTQG for example if UTQG is: 500 AA A, the wet traction piece is the second piece, the "AA".
Measured in 32nds of an inch, this metric shows how much tread life is left on a tire, with the tire's traction & stopping capabilities greatly diminished at 4/32nds and less. Tire manufacturers include "tire wear bars" at 2/32nds to indicate when your tire is worn out.
The highest inflation pressure (measured in pounds of force per square inch, PSI) the tire is designed to contain, and should only be used when called for by the vehicle placard.
An identifier of a particular tire line and size combination assigned by the tire manufacturer.
Shipping weight (lbs)
The measurement of width from a tires inner sidewall to the outer sidewall.
The range of widths the rim of the vehicle can be for this tire to be safely mounted on.
The diameter of a tire that is inflated without any load applied.
