There are two ways forklift tires can be fixed; standard or press on. Standard tires need to be fitted in the exact way that car tires are fitted whereas press on tires are more straightforward to fit on a forklift. These tires are less durable though, especially when it's running on uneven surfaces or rough terrain. The size of a tire should be determined by first deciding on the approximate load amount on each forklift wheel. Generally, picking the tires with the lowest inflation pressure when it carries the load is the best type of tire. Another important factor to consider while choosing tires is how often the forklift would be used and the conditions under which it will be used. For regular, continuous work, especially over rough terrain, pneumatic tires are the ideal option, whereas rubber tires should be used on even surfaces. Polyurethane tires should only be used indoors.
