KNOW YOUR TIRES
THE ANATOMY OF A TIRE
It's important to familiarize yourself with the basic components of agricultural tires.
Then, you can understand the role each part plays in ensuring your farms tires are achieving top
performance when you head into the field for soil prep, planting, spraying and harvest.
Beads anchor the tire to the rim and allow the tire to stay "seated" on the wheel.
Bead Fillers stabilize the lower sidewall by enveloping the bead and extending up in the sidewall to maximize stability, steering response, and case durability.
Liners protect the cord body by insulating the tubes from the cords. Liners are essential for resisting air and moisture permeation.
Belts determine the shape, or footprint, of the tire. Belts work in conjunction with the cords to add stability and strength.
5. TREAD DESIGN
Treads serve to interact with the soil or paved surface and provide traction. Tread design varies between tires to maximize traction and resist wear and tear.
Sidewalls are made of flexible rubber and provide lateral stability. The sidewalls keep the body plies and innerliner of the tire protected. Sidewall flex is a big factor in deciding what tire is right for what job and what piece of equipment.
7. LUG BUTTRESS
Lug depth is important for traction. Together with the lug buttress, this component provides tread stability.
8. BODY PLIES
Cords run radially from bead to bead and determine the strength of the tire, determine its load capacity and provide lateral stability.
RADIAL TIRES, OR BIAS TIRES?
WHAT ARE THE ADVANTAGES?
Bias ply tires engineered with multiple plies of rubber criss-crossed over one another. Thus, the sidewall and tread are connected. Conversely, radial tires are made of two separate parts. The body plies run perpendicular to the bead and the undertread hugs the tires circumference with steel belts. This way, sidewall movement isn't transferred into the tread so radials offer reduced soil compaction. To sum up the debate, bias tires are great for forestry, or non-tillage equipment and they cost less than radials. Radials have a larger footprint for better traction and reduced soil compaction. Plus they're more fuel efficient. A certified Firestone Ag Dealer can help to determine the correct type of tire for your needs.
Bias tires ares perfect for smaller, lightweight production equipment that requires extra stability for non-tillage work.
• Stiff sidewalls are ideal for forestry and avoiding cuts and punctures
• Crisscross body plies create internal friction that create stability but run hot
• Cost effective options for older or lightweight equipment
• Best for environments where sidewall punctures are common
• Not for every day tillage/production
Dependable fuel economy
Increased traction helps with fuel economy and allows you to cover more ground. Radial tires can last up to 30% longer than bias tires. Radial tires with AD2 technology allow you to carry more load at lower inflation pressure.
• Shows an advantage of 6% to 14% in traction, fuel efficiency and reduced wheel slippage over bias tires
• Bigger footprint, longer tread wear and a smoother ride
• More resistant to tread cuts and punctures
• Typically easier to repair
• Run cooler
• Ideal for larger equipment
AD2 SUPER RADIALS
Heavy loads. Lower pressure.
AD2 tires have a larger footprint that can help improve the productivity of today's heavier
equipment with less time in the field and reduced fuel consumption.
• Carry the same loads at lower pressure
• Reduced soil compaction
• Improved traction
• Smoother ride
What type of soil you're working with determines what type of farm tire tread you need. Read the
traction comparison info below to select the right tread for the job, or see a traction comparison chart.
- R-3 is non-aggressive pattern for minimal ground disturbance sites such as airports, golf courses, cemeteries or roadside maintenance
- Relatively closed tread pattern in designed to evenly distribute the load on maintenance trailers and grain carts
Construction and Light Industrial
- R-4 tires are intended to be operated on hard surfaces with backhoes and small end loaders
- Tread depth is approximately 70% of the R1 tread
