Product description
Features and Benefits
- Five rugged, contra-diagonal ribs with aggressive buttressed shoulders give full directional and steering stability on steering axles, as well as excellent traction and braking on drive axles.
- Newly developed steel cord top belt helps protect against rust and stone penetration damage, while minimizing tread distortion and heat generation.
The Yokohama 315 / 80R22.5 Y773 (22) tires were specially developed for sanitation vehicle operations that require a high load-carrying capacity per tire, cut protection, long-wearing tread compound, and a durable casing that allows multiple retreads. These tires were also designed for smooth, even wear, good traction and fuel economy. Since it is a special design, they must be installed and operated only on sanitation vehicles in accordance with the following guidelines:
- During its original tread life, the tire must be mounted on a 9.0" or 9.75" rim width.
- Only after the tire has been retreaded may it be installed on an 8.25" rim. The buff radius at retread must be 27" to accommodate the 8.25" rim width.
- Tires to be reinstalled on 9.0" rim widths after retreading must be buffed to 28" before the retread is installed and the retreading process is completed.
- Vehicle speeds must not exceed 55 miles per hour.
- Normal maintenance procedures involving inflation pressures, repairs or retreading must be performed according to Yokohama's recommendations and those of the retread and repair material manufacturers.
- If the rim/wheel specifications state a lower maximum weight-carrying capacity at a lower maximum air pressure than the tire, the maximum load-carrying capacity of the tire is lessened. That, in turn, governs the maximum load capacity of the tire/wheel assembly.
Cautions - Use of 20 vs. 22 ply rated tires.
Use of the 20 ply rated tires on a vehicle with a 20,000 lb., front axle down rates the maximum and legal carrying capacity of the front axle to 18,000 lbs.
The 22 ply rated Y773 is appropriate for use on vehicles with front axle capacities of either 18,000 lbs. or 20,000 lbs. The design rim width is 9.00 inches for both tires. Maximum air pressure is 130 psi for both tires. Additionally, section width and diameter are the same for both tires.
However, a tire upgrade alone, does not upgrade the carrying capacity of the front axle of the vehicle.
To legally and safely carry 20,000 lbs. on the front axle requires front end components, wheels and tires to all be rated at 20,000 lbs.
- Wheel ratings are stamped on the wheel.
- Axle capacities can be verified by checking the vehicle line sheet, or contacting the axle manufacturer with the axle tag number.
- Carrying capacities of tires are marked on the sidewall.
Summary
The legal and maximum carrying capacity in these applications, is dependent on the lightest rated item: tire, wheel, or front suspension/steering component. Operational Speed: Maximum operational speed is 55 mph
