16 Ply 11R 22.5 Steer Tires for Commercial Trucks
Overview of 11R 22.5 Steer Tires 16 Ply
11R 22.5 steer tires with a 16 ply rating are designed for the demanding needs of large commercial trucks. The 11R size denotes these tires have a rim diameter of 22.5 inches and an overall diameter of approximately 44 inches when properly inflated. The R indicates they are of radial construction, featuring radial plies for improved tread life and fuel efficiency over bias ply tires.
Benefits of 16 Ply Steer Tires
The 16 ply rating signifies these tires have 16 layers of rubber coated fabric plies running from bead to bead at approximately 23 degrees to the centerline of the tire. This robust internal structure allows 11R 22.5 steer tires to handle heavy loads at high inflation pressures up to 120 PSI.
Key benefits of commercial 16 ply steer tires include:
- Long tread life – More plies mean greater durability and mileage to first retread.
- Puncture resistance – The thick tread and sidewall resist damage from debris or curb impacts.
- Load capacity – Capable of carrying heavy loads on the front axle of 5500-8000 lbs per tire.
- Improved stability – The sturdy structure provides excellent tracking and control.
Tread Designs and Traction
There are various tread designs available for 11R 22.5 steer tires to suit different applications. Common options include:
- Regional service – Mixed highway and city delivery driving on mostly paved roads.
- Urban service – Stop-and-go driving for metro applications.
- On/off road – For combined highway, city, gravel and dirt driving.
- Mud and snow – With aggressive tread lugs for maximum winter traction.
Modern tread compounds use specially engineered silica to provide long wear, low rolling resistance for good fuel economy, and reliable wet/dry/winter traction.
Retreads
The sturdy carcass of 16 ply 11R 22.5 steer tires allows multiple retreads over their service life. Typical retreadability is 2 or 3 times. Retreated tires offer an economical solution costing 40-50% less than comparable new tires.
Maintaining Proper Inflation
Like all commercial truck tires, 16 ply 22.5 steer tires require regular inflation pressure checks. Under inflation is the most common cause of premature tire failure. Always maintain pressures within 5 PSI of the manufacturer's recommendations based on load.
Tire Pressure Monitoring Systems
Given the importance of proper inflation, tire pressure monitoring systems (TPMS) are highly recommended for commercial trucks running 16 ply 22.5 steer tires. There are various TPMS technologies available including:
- Battery powered sensors mounted inside each tire on the wheels.
- Antennae mounted valve caps that actively monitor individual pressures.
- Tire maintenance software that tracks pressures manually input by drivers and technicians.
Investing in an automatic on-board TPMS can pay big dividends preventing downtime from blowouts and other tire failures caused by low pressure.
Regular Inspections
Aside from maintaining proper inflation, 16 ply 22.5 steer tires should be periodically inspected inside and out for any signs of damage, abnormal or uneven wear, cracks, cuts, bulges, missing chunks, etc.
Any tires with injuries that expose cords should be immediately replaced. Ensure there are no objects embedded in the tread as they can work their way deeper eventually causing tire failure.
When to Replace 11R 22.5 16 Ply Steer Tires
Use the penny test to check tread depth around the tire. Insert an upside down penny into the tread grooves. If you can see the top of Lincoln's head, it means there is only 4/32 inch of tread remaining indicating the tire should be replaced. Most steer tire casings have a remaining legal and serviceable tread depth of 2/32 inch when taken out of service.
Assessing Casing Condition
In addition to insufficient tread depth, 11R 16 ply steer tires should be removed from service if sidewalls are worn or damaged, cords or belting material is exposed through cracks or cuts, flat spotting has occurred, or the casing is damaged from running under inflated for lengthy periods.
An internal inspection can determine if casing damage like loose cords or separated plies makes it unsafe for retreading. Inspect the inner liner as well for any signs of bulges, cracks or holes.
Any steer tire with casing damage or otherwise deemed unfit for retreading should be fully replaced.
