The buyer simply accepted the tires that were installed at the time of purchase. Today, the tire buyer has many options. A wide range of sizes, tread designs and load ratings is available in either radial or bias ply design. Selecting the proper tractor tire requires careful evaluation of the conditions in which it will operate. The first factor to consider is the type of load the tractor will pull.
Soil type is another important factor.
Finally, the price and expected life of the tire should be considered. Getting the best performance from your investment is what tire selection is all about. You want to get as much of your tractor's power to the drawbar as possible while keeping tire costs low. Select tires that fit your budget and operating conditions while allowing your tractor to operate at a desirable wheel slip level. Proper tractor ballasting is essential to optimizing tractor performance.
