How this system works:
Your four tyres are the only things that come into contact with the road. As a result, they are susceptible to wearing and tearing due to the constant contact with the road when you drive. Your four wheels are designed – through alignments, tyre specifications, and proper air pressure – to share the contact with the road, and to wear in an even manner. When something sets one wheel out of balance, the tyre on that wheel is susceptible to abnormal wear and tear.
Common reasons for this to happen:
There are a number of different issues that can result in one tire wearing faster than the other three:
- Improper air pressure in one tire: Tires are designed to have a specific level of air pressure in them. If they are under-inflated, the outside of the wheels can wear too much, and the tire is susceptible to cupping. If they are over-inflated, the middle of the tyre is the only part in contact with the road, and the pressure of the tyre can cause the vehicle to bounce slightly, causing further damage to the tyre.
- Wheel misalignment: An alignment sets your wheels at the ideal angles, so that each wheel is lined up with the others. This allows the car to be able to drive in a straight line, corner effectively and predictably, and it helps the tyres wear slowly and evenly. If the wheels are not properly aligned, one tire may be subject to more wear and tear than the other three.
- Tyres have not been rotated: It’s important to have your tyres rotated on a regular basis, because different corners of your vehicle may experience different wear and tear than others. For instance, one of your right tyres (front for a front-wheel drive car, rear for a rear-wheel drive car) will be subject to the most wear and tear, especially in a powerful vehicle. This is because slightly more power goes to the right side of the vehicle, because that is the side that hosts the drive wheel. This wear and tear is minimal enough that it will be negated by proper tyre rotation, but if the tires are not rotated regularly, this may result in noticeable wear in one of the tyres.
- Damaged suspension: Many of the components in the suspension system – such as the shock absorbers, struts, control arms, and ball joints – can have an impact on tire tread wear. The suspension connects your wheels to the frame of your car, and helps evenly distribute the weight of the vehicle and the impact of the road. If a shock absorber, strut, control arm, or ball joint becomes damaged, it can put large amounts of pressure on one wheel. This can cause abnormal wear, or simply throw off the alignment, which will eventually result in uneven wear and tear.
What to expect:
A top-rated mobile mechanic will come to your home or office to determine the cause of one wheel wearing faster than the others, and will then provide a detailed inspection report that includes the scope and cost of the necessary repairs.
How it’s done:
Before replacing your tyre, a mechanic will thoroughly inspect your suspension system to make sure that a larger issue is not in effect. If there is something wrong with the struts, shock absorbers, ball joints, or control arms, the mechanic will replace them, and then replace the tire. All four tires will be checked to make sure that they’re in similar condition, and filled with the correct amount of air pressure.
How important is this service?
Services that feature tyres are always important. A tyre that is very worn will have a shorter lifespan and is susceptible to blowing out. One tire that is wearing faster than the others can be a sign of a larger issue with the suspension system, which will only become further damaged if it is ignored. You should always schedule an inspection as soon as you notice that one tyre is wearing faster than the others.
