I1, I2 & I3 Farm Implement Tires
Implement tires are the unsung workhorses behind your tractor, supporting everything from plows, planters, and grain wagons to hay equipment and tillage tools. Tires4That carries I1, I2, and I3 implement tires in a wide range of sizes from the brands that ag equipment dealers and farmers have trusted for decades.
What To Look For In I1, I2 & I3 Farm Tires
The I-designation describes the tread pattern and intended use for agricultural implement tires. I1 (also called rib or highway implement) tires have a smooth or lightly ribbed tread designed for free-rolling axle use, primarily for equipment that travels on roads as well as fields. These are among the most common implement tires in the market. I2 tires have a moderate tread pattern with some bite, suited for implements that see mixed field and transport conditions. I3 tires have a more aggressive traction tread for implements that need some drive-type grip in the field, such as certain seeders or tillage equipment with powered components. When selecting an implement tire, confirm the ply rating meets or exceeds your implement's rated axle load. Implement tires are often run at high loads for their size, and choosing an undersized tire leads to rapid failure and blowouts.
Frequently Asked Questions
Q: What is an I1 implement tire?
A: The I1 is a ribbed or smooth-tread tire designed for free-rolling axle use on agricultural implements. It rolls smoothly on both road and field conditions, minimizes soil disturbance underneath the equipment, and serves as the standard choice for wagons, planters, and most pull-behind machinery.
Q: What's the difference between I1, I2, and I3 implement tires?
A: I1 tires have a ribbed or highway-style tread for free-rolling implement axles. I2 tires have a more defined tread pattern for mixed field and road use. I3 tires are the most aggressive, with a traction-style lug pattern suited for implements that need field grip. Most pulled farm equipment uses I1 tires.
Q: Can I replace implement tires with regular trailer tires?
A: In some cases, yes. ST trailer tires and I-series implement tires overlap in size and application for lighter equipment like small wagons. However, for heavy agricultural implements, I-series tires are specifically rated for the high static loads and low-speed field use that implement axles experience. Always verify that the load rating matches your implement's axle capacity before substituting.
Q: How do I find the right implement tire size?
A: The size is printed on your existing tire's sidewall. Common implement tire sizes include formats like 11L-15, 7.60-15, and 16.5L-16.1. Match the width, construction (L for low-profile bias, straight numbers for standard bias), and rim diameter. Also, confirm the ply rating matches or exceeds your axle load rating.
Q: What brands do you carry for implement tires?
A: We carry I-series implement tires from Alliance, Goodyear Farm, Galaxy, Titan, CropMax, Deestone, and Kenda across the most common sizes for farm wagons, planters, and pull-behind equipment.
