The replacement time for agricultural tires varies depending on a number of factors, including the brand of tire, manufacturing process, conditions of use, wear and tear, and aging. Ideally, new agricultural tires that are properly handled and stored in good conditions typically have a shelf life of 5 to 6 years. However, the exact replacement interval needs to be evaluated and adjusted according to the actual condition of the tires.

Usually, the replacement cycle of agricultural tires is 2~4 years or more than 10,000 kilometers. However, if you find that the tires have obvious wear, cracks, insufficient air pressure or the tread is worn below the safety marking line, they should be replaced in time.

In addition, the environment in which the tires are used, the load, etc. will also affect their replacement intervals. For example, tires for agricultural machinery that are frequently driven on uneven surfaces and do not have a garage to park them in the open may have a shorter life span. On the contrary, the service life of tires driven on smooth roads and parked in a garage may be relatively longer.

Therefore, it is recommended to regularly check the wear and aging of agricultural tires and determine whether they need to be replaced according to the actual situation. At the same time, choosing tire brands and models of reliable quality and suitable for the use environment, as well as correct use and maintenance methods, will help to extend the service life of tires.
