To measure skid steer tire size for over-the-tire (OTT) tracks, check the tire sidewall for size markings like Width x Rim Diameter (e.g., 10x16.5) or Height x Width x Rim Diameter (e.g., 27x10.5-15). If not visible, measure tire width and rim diameter manually, then verify with your OTT track manufacturer for compatibility.
How Do You Find the Tire Size on Your Skid Steer?
Look at the tire’s sidewall for printed size information. Common formats include:
-
Width x Rim Diameter (e.g., 10x16.5): width is tread width in inches; rim diameter is in inches.
-
Height x Width x Rim Diameter (e.g., 27x10.5-15): first number is overall tire height; second is width; third is rim diameter.
What Should You Do if the Tire Size Is Not Visible?
Measure the tire width at the widest point using a tape measure. Then measure the rim diameter across the rim’s widest points. Use these numbers to find matching OTT track sizes or consult the manufacturer with your measurements for proper fit.
How Do You Measure Your Machine’s Wheelbase?
Measure the distance between the center of the front axle and the center of the rear axle of your skid steer. This is essential to calculating the correct OTT track length that fits your machine.
Which Formula Helps Calculate the Proper OTT Track Length?
Use the formula:
Where tire circumference can be calculated as . This formula ensures the correct track will fit without excess slack or tightness.
Why Is Clearance Important When Installing OTT Tracks?
OTT tracks add size to your machine, so ensure that there is enough clearance—typically 2.5 to 3 inches—between the inside of the tires and the machine frame. Proper clearance prevents rubbing and damage. Wheel spacers may be needed if clearance is insufficient.
When Should You Consult an OTT Track Supplier?
After recording tire size, wheelbase, and clearance, consult manufacturers or distributors to select compatible OTT tracks. Different OTT brands may have specific sizing and adjustment features tailored to machine models.
How Does Tire Size Differ from Rubber Track Size?
Tire size describes dimensions like width and rim diameter, while rubber track size involves track width, pitch (distance between links), and number of links. The track size must be chosen to fit the tire size the OTT tracks are designed for.
Could Improper Tire Measurement Lead to OTT Track Issues?
Yes, inaccurate tire or wheelbase measurement can lead to choosing an OTT track that is too tight or too loose, causing premature wear, damage, or operational issues, compromising machine safety and efficiency.
What Are Common Skid Steer Tire Sizes for OTT Tracks?
Popular skid steer tire sizes compatible with OTT tracks include 10x16.5, 12x16.5, and 14x17.5 for pneumatic tires. Corresponding solid tire sizes translate dimensions differently, so understanding your skid steer tire type is key.
How Do You Maintain Tires and OTT Tracks for Optimal Performance?
Maintain proper tire inflation and track tension, remove debris regularly, and check clearance to prevent damage. Replace worn tires and OTT tracks in pairs to ensure balance, stability, and optimal machine operation.
