- How often should bicycle tires be changed
Bicycle tires need to be replaced when they are used for three years or 80,000 kilometers. Of course, it also depends on the situation of the tires. If the pattern of the tires is not too worn at this time, and there are no bulges or cracks, it can be extended for a period of time, but it should be replaced in about four years at most ,after all, rubber will be aging.
If the tires have not been replaced for a long time, not only will it affect the use, but the tires will also blow out when riding. So in order to avoid unsafe things, we must regularly change tires for bicycles.
- How to change the bicycle tires
①Remove the tires
First remove the old tires from the bike.
Be careful not to hit the brake disc and brake pad during the disassembly process to avoid damage. Due to the high torque value of the rear wheel axle nut, it is recommended to use a wrench with a longer handle, which will be more efficient in applying force.
②Deflation
After removing the tire,use a special valve tool to screw the valve.After the tire is completely deflated,put the tire on other old tires or on the workbench to ensure that it will not wear to the disc brake rotor during the next action of removing the tire lip.
③Remove the tire from the wheel
Remove the tire from the wheel,you shall press the entire wheel with your knees to borrow force,and then insert the tire lever along the edge between the wheel and the tire,and pry the tire lip about 3CM away from the wheel,and move 3-5CM each time to pry it off slowly. This method can be used on both sides of the rim until the entire tire comes off the rim.
④Install new tires
First, apply the appropriate amount of special lubricant (such as tire paste) to the corresponding assembly position of the tire lip and rim, and confirm whether the tire direction is correct.Generally, there will be a direction mark on the tire edge,which should be assembled on the rim according to the rotation direction indicated by the mark.
At the beginning of the installation, press it by hand first,then use the tire lever to put the tire on the rim.
Be careful not to damage the rim during the process, and finally press it with your hands to install the tire on the rim smoothly.
⑤Tire inflation method
After assembling the tires onto the wheels and fill with some air,manually adjust the waterproof wire (safety line) and the outer edge of the rim to maintain a certain true roundness,then inflate to standard air pressure.
Before putting the tire back on the bike, the tire surface can be washed with detergent.
⑥Put the tire back on the bike
Install the tire on the bike in the reverse order of the first step of tire removal.And pay attention not to scratch other parts of the bike during installation.Remember to install the spacer and lock the nut back to the original preset torque value,so far all the steps of bicycle tire removal and installation are completed!
