If you are looking for rubber tracks for a skid steer loader this is your best option on the market right now. These are loose fitting tracks so the are easier on the machine than some other products that have existed in the past. The tracks have an expansion link that can be used to tighten the tracks as the tires wear. You need to watch for clearance issues when installing these. They are big tracks so make sure you have clearance around the frame, bucket and boom. If you have a clearance issue you can add a boom stop, off-set rims or a spacer kit to solve the problem. Sometimes is is best to buy a new set of tires to fit the tracks. CAMSO tires seem to work best, but that makes since when they make the tracks. I would not try and use these tracks with solid tires. And I would not recommend using foam filled tires either. Every condition is different but I would estimate you get around 1000 hours out of these tracks before they need to be replaced.
