Choosing the right size tractor tire chains is essential for safety and performance. Using a chain that doesn’t fit your tire properly can cause damage to your tractor or the chains themselves. This guide provides a clear tractor tire chain size chart to help you find the perfect fit for your tires.
How to Measure Your Tractor Tires for Chains
Before choosing chains, you need to know your tire size. You can find this information printed on the tire sidewall. Tire sizes usually look like this: 18.4-38 or 420/85R34.
- Section Width: The width of the tire in inches or millimeters.
- Aspect Ratio: Height of the sidewall as a percentage of the width (mainly for metric tires).
- Rim Diameter: Diameter of the wheel rim in inches.
Knowing your tire size ensures you pick chains that fit snugly and provide maximum traction.
