The tires of small mixer often contact with the ground and are often subject to great pressure, so there are very strict requirements on the tires, and the mixer must replace the tires in time after using for a period of time. The first step to replace a tire is to remove the tire. So how should we dismantle it?

一、拆卸轮胎时，应在清洁、平整、枯燥、坚硬且无油污的空中上停止，以避免沙土、杂物等落到外胎内壁或粘附于内胎外表损坏内胎，并避免油污粘附于轮胎上腐蚀轮胎。

1、 When removing the tire, it should be stopped in a clean, flat, dry, hard and oil free air to avoid sand, debris, etc. falling on the inner wall of the outer tube or adhering to the outer surface of the inner tube, damaging the inner tube, and preventing the oil stain from adhering to the tire and corroding the tire.

二、拆卸小型混凝土搅拌车轮胎应由有实践经历的人员操作或指导，切不可乱敲乱打，以免使轮圈产生锐边、凹痕、龟裂等缺陷，并要坚持轮圈的清洁，避免锈蚀损坏。

2、 The removal of small concrete mixer tire should be operated or guided by experienced personnel. It is not allowed to knock and hit randomly, so as to avoid sharp edge, dent, crack and other defects on the wheel rim. The wheel rim should be kept clean to avoid corrosion damage.

三、只能运用专用工具和撬棒停止拆装，停止运用螺丝刀之类的锋利工具。

3、 Only use special tools and crowbars to stop disassembly and assembly, and stop using sharp tools such as screwdrivers.

四、拆卸办法。放掉轮胎中的空气，应用气门帽将气门芯拧出，打下气门嘴固定螺母，用双脚踩踏或用锤子重击外胎侧面，使轮胎的胎圈脱离轮圈边缘进入轮辋中部凹槽内，将气门嘴推进轮圈内。在气门嘴左近将撬棒插入胎缘轮辋之间，将胎缘撬起，同时在撬胎棒的对面用力紧缩外胎胎壁，使外胎尽量移向轮辋中部凹槽内，行将撬出的部位尽量放松。

4、 Disassembly method. Let off the air in the tire, screw out the valve core with the valve cap, screw down the valve fixing nut, step on the side of the outer tire with both feet or hit the side of the outer tire with a hammer to make the tire bead separate from the rim edge and enter into the groove in the middle of the rim, and push the valve into the rim. Insert the crowbar between the bead rims at the left side of the valve, pry up the tire bead, and at the same time, tighten the tire wall of the outer tire on the opposite side of the tire prying bar, so that the outer tire moves to the groove in the middle of the rim as far as possible, and the part to be pried out shall be relaxed as far as possible.

五、假如小型搅拌车轮胎运用日久，外胎锈死在辋圈内而不容易取下时，能够将轮胎平放在洁净的空中上，用撬棒在胎口与辋圈之间撬开一定间隙，在辋圈与外胎的分离部倒些肥皂水或清水，并用铁锤沿l轮圈外侧稍加锤击，使水在振动的过程中从缝隙处渗入生锈面，待浸透后，外胎便容易拆下来。

5、 If the tire of small truck mixer has been used for a long time, and the tire rust dies in the rim and it is not easy to take it off, the tire can be placed flat in the clean air, pry a certain gap between the tire bead and the rim with a crowbar, pour some soapy water or water in the separation part of the rim and the tire, and hammer slightly along the outer side of the L wheel rim with a hammer, so that the water can penetrate into the rusty surface from the gap during vibration After soaking, the outer tube can be easily removed.

小型搅拌车轮胎连接着很多配件，需要在拆卸的过程中不仅要注意方法，而且还要注意拆卸的过程。在整个拆卸过程中记得将拆下来的零件统一放好。

There are many accessories connected to the tire of small truck mixer. It is necessary to pay attention not only to the method but also to the process of disassembly. In the whole process of disassembly, remember to put the removed parts in a unified way.
