Wear indicator is located at the bottom of the main groove，Evenly distributed around the tire。Wear indicator is like a fine smooth rubber strip in the tread，When wear reaches a certain degree，It will be displayed。When you see these wear indicators，This means that the tire needs to be replaced。When the remaining tread depth of the tire is reached1。6Mime should replace the tire。
Do I have to replace existing tires with the same specifications？
Yes，You should use the same specification tire
Whether the tire balance should be adjusted？
The correct balance is critical to achieving the best performance of the car.，This is especially important for high-speed driving on highways.。If the tire and wheel assembly is unbalanced，Its vibration（Left and right swings）Or bounce（Tire and wheel assembly top and lower bumpers）Will lead to instability of the vehicle。therefore，It must be ensured that the tires and wheel components have static and dynamic balancers.。
What is the correct calibration？
When all suspension systems and steering components are normal，When the tire and wheel assembly can travel straight，It can be assumed that the car has been calibrated correctly。Corrected calibration，To ensure uniform tread wear and precise steering。The front and rear wheels are not uniform，Or change in car steering or steering response（which is， Drag to one side）It is all unmatched four-wheel positioning。right now，Many cars have a rear suspension that can calibrate and adjust。Four-wheel positioning calibration can improve tire life and automobile performance，Bring more comfortable driving experience。

Excessive abrasion of the tread。
Overweight of tires is easy to slip on the road，And it is likely to be damaged by the road pit and other road hazards.。Tire tread depth is not less than1。6Mm if the tread depth is less than1。6Millimeter tire should be replaced in time。In order to facilitate you to find the tread problem in time，Tire“Wear indicator mark”。When the tread and wear indicator are usually（which is， Thin rubber strip），It indicates that the tire wear has reached the maximum，Tire should be replaced immediately。
You can also use a caddy coin to make a simple test。Let Lincou head towards coins， Insert the edge of the coin into the tread。If the tread covers the head of Lincoln，It shows that the tread is good。If Lincoln's head is completely visible，This means that the replacement tire is。
There are foreign matter on the tread
Check small stones， shattered glass， Metal parts and other foreign objects wedged into the tread，Carefully take them。If these foreign matter deep into the tire during driving，May lead to serious problems。
Damage area
crack reduce Split Leak， Holes， Bumps on both sides of the tread or tire may cause serious problems。If these phenomena exists，Tires may need to replace。
Leak slowly。Pantheetic pressure reduction，but，If you find the air leak（Tire must be inflated once every day），Please check tires， Wheels and valve nozzles should be repaired or replaced with tires。
cap。
Small caps on the tire valve rod can prevent moisture and dust from entering the inside of the tire。and so，Ensure that the valve cover of each tire is installed correctly。In addition，Install new stem assemblies at the same time when changing tires。

Second point：If the remaining groove depth of the tire tread is or less1。6Millimeter（There is an indication mark in the longitudinal direct slot of the tire tread，Depth），Tire must be replaced，Since the tire is greatly reduced，Vehicles are more dangerous in wetlands。
In addition，Damaged tires should also pay attention to whether they need to be replaced。E.g， Although the discharged tire can still travel in an inflatable state，however， Because the internal structure of the tire may have been damaged， therefore， It is recommended to replace the new tire in time.。How to determine if the damaged tire can continue to use，Please consult the company to designate the dealer for professional examination，Then determined。
