Since small loaders often have flat tires when working on poor construction sites (such as rock surfaces), small loader manufacturers have summarized a method to quickly replace loader tires, as follows:

(1)启动机器，然后寻找一块平坦开阔的场地，压下动臂升降杆，利用动臂支撑使前轮离地，然后用支架支撑在闪桥靠近爆胎的一侧，并将后轮楔好。

(1) First start the machine, then look for a flat and open place, press down the boom lifting rod, use the boom support to lift the front wheel off the ground, and then use the support to support it on the side of the flash bridge near the flat tire, and wedge the rear wheel.

(2)利用撬杠等工具，拆卸挡圈及锁圈然后检查轮胎衬垫与轮辋外表面是否粘连。若发生可撤掉支撑物，使机器在短距离内慢速往复运行，直衬垫与轮辋外表面脱离；严禁转向和高速行驶，以免损坏内胎。然后，前轮重新支撑起来。

(2) Use pry bars and other tools to remove the retaining ring and lock ring, and then check whether the tire liner is adhered to the outer surface of the rim. If it happens, the support can be removed to make the machine run back and forth slowly in a short distance until the gasket is separated from the outer surface of the rim; It is strictly forbidden to turn and drive at high speed to avoid damaging the inner tube. Then, the front wheels are propped up again.

(3)将内、外胎的相对位置作好标记，以便查找、异物和修补轮胎。

(3) Mark the relative positions of inner and outer tires to find and remove foreign matters and repair tires.

(4)利用撬杠等工具，将轮胎从轮辋上拆下。注意，动作要轻柔配合要默契，避免被轮胎砸伤，并且要保护好气门嘴。

(4) Use pry bars and other tools to remove the tire from the rim. Note that the action should be gentle and tacit, to avoid being injured by the tire, and to protect the valve mouth.

(5)外胎被钉子等细长异物扎伤后，若表面无明显创口或创口较小，则此外胎可继续使用(因为装载机轮胎属低压胎，且运行速度比较慢)；若创口较大，则进行修补(因为机器运行时，轮胎受挤压磨擦，时间一长会损坏内胎，甚创口越来越大、内胎突出，造成轮胎报废。

(5) After the outer tire is stabbed by slender foreign bodies such as nails, if there is no obvious wound on the surface or the wound is small, the outer tire can continue to be used (because the loader tire is a low-pressure tire and the running speed is relatively slow); If the wound is large, repair it (because when the machine is running, the tire is squeezed and rubbed, and the inner tube will be damaged over time, or even the wound will become larger and larger, and the inner tube will protrude, causing the tire to be scrapped.

(6)若是新内胎，将气门嘴底部的螺栓拧紧，以防漏气；然后将外胎内腔的异物，并撒入适当的滑石粉，涂抹均匀。为了使衬垫与内、外胎贴紧，在装入内胎后应给内胎适当充气，再塞入衬垫。

(6) If it is a new inner tube, tighten the bolts at the bottom of the valve to prevent air leakage; Then remove the foreign matters in the inner cavity of the outer tube, sprinkle appropriate talc powder, and apply evenly. In order to make the liner close to the inner and outer tubes, the inner tube should be properly inflated after installation, and then the liner should be inserted.

(7)将轮胎装到轮辋上，装上锁圈、挡圈；安装过程中要保护好气门嘴。

(7) Install the tire on the rim, and install the lock ring and retaining ring; Protect the valve nozzle during installation.

(8)用车载空压机给轮胎充气。

(8) Inflate the tires with on-board air compressor.

(9)压下动臂升降杆，取出支架；此换胎完毕，整个过程大约需要50min。

(9) Press down the boom lifting rod and take out the support; At this point, the whole process takes about 50min.

更换后轮胎时，则需要另一台装载机或者其他起重设备辅助，将后轮胎支撑起来，其他程序则与更换前轮胎相同。

When replacing the rear tire, another loader or other lifting equipment is required to support the rear tire, and other procedures are the same as those for replacing the front tire.
