The front and rear wheels of forklift trucks are different in size. Will it damage the gearbox?

The first thing to know is the size of the tire. 825 and 750 should be 8.25 inches and 7.50 inches respectively, representing the width of the tire after it is fully inflated. 16 is the outer diameter of the steel ring or the inner diameter of the tire, also in inches. The size of the tire outer diameter is mainly related to the tire inner diameter. Please check whether the outer diameters of these two kinds of tires are the same. If they are the same, they can be replaced without damaging the gearbox. In addition, it should be noted that the tread width of 750- 16 is not as wide as that of 825- 16, and the adhesion is even worse. If you have to change it, you should change it to a cross-country tire (big pattern).
