What causes tires to wear on the inside? It is a common problem faced by many drivers.
Tires wear on the inside due to the non-functionality of the steering and suspension components. It results from incorrect toe settings, worn ball joints, tie rod ends, control arm bushing, and damaged springs that must be replaced before the alignment. If the car is in good condition, a simple wheel alignment should stop the inside tire tear.
Other factors cause a tire to wear out, thereby creating noise or vibration. So let’s explore in detail what causes tires to wear on the inside.
Why Are My Tires Wearing on the Inside?
Generally, tires wear on the inside depending on the level of usage and the primary reason is that the threads of the tires become thin.
Tires wear out for various other reasons including, excessive center wear caused by over-inflation; tie rod wear that causes feathered wear pattern across the front tires; cupping, or a dished pattern, caused by worn shocks.
What Causes Tires to Wear on the Inside?
- Camber Problem
- Worn Tie Rods
- Worn Ball Joints
- Worn Struts or Shock Absorbers
- Bad Wheel Alignment
- Improper Inflation Pressure
- Toe setting
Camber problem is one of the top causes of tire wear on the inside. It occurs when the inside of the tread on the front tires wear out faster than the center or outside edge, thereby affecting how straight up or down the car tire is located with the car’s full weight resting on it.
Camber angle allows car tires to sit flat on the road. However, if your wheels are out of alignment, it causes the camber angle to either be ‘positive’ or ‘negative.’
A negative camber angle allows the top of the tire to angle inwards and the bottom of the tire stationed further than its top results in inner tire wear.
Worn Tie Rods
Tie rods is also one of the main cause of tires wear on the inside.
If you do not grease the tie rods regularly, it leads to faster wear out, thereby affecting the front end of the alignment. So, ensure that you grease the tie rods and it should be done during each oil change tire.
Worn Ball Joints
Typically worn ball joints can cause the tires to wear on the inside. The ball joints of your vehicle connect to the tie rods to ensure the car steering remains in the right direction.
You can observe that ball joints of your car are worn out when you hear sound from your suspension while climbing speed bumps or when the ball joints near tire wear on the insides do not respond speedily to the steering.
Worn Struts or Shock Absorbers
Worn struts or shock absorbers can also cause tire wears from the inside. In this regard, the vehicle wheels bounce excessively, especially on rough terrains, which results in the inner or outerwear pattern on the tread.
Moreover, it vibrates the steering wheel whenever you hit a speed bump.
Bad Wheel Alignment
Bad wheel alignment causes inner tire wear; typically, the camber of your vehicle knocks out of proper alignment.
Your car may suffer bad alignment from pothole collisions, and the steering may pull in one direction while driving on a surface-level road.
Improper Inflation Pressure
Every manufacturer recommends a specific level of tire inflation. If you overinflated or underinflated tires, it causes wear on the inside.
Make sure to follow the manufacturer’s recommendation for enhanced tire life.
If your vehicle toe settings are off, the front of your tires may point outward or inward, which causes excessive wear on the inside of your tires.
The reason is that more forces pull on the inside of your tires. However, if the toe alignment is properly done, your tires should be facing straightforward, not inward or outward, thereby reverting or not leading to the wear of the inner tire.
How to Fix Inner Tire Wear
Below are the ways to fix inner tire wear:
- Wheel alignment
- The tire should be Properly Inflated.
- Regular Wheel Balancing
- Fix or Replace Damaged Suspension Components
- Regular Check on the Tire Tread Depth
Wheel alignment is a major step to ensure the lasting life span of your tires. It is paramount that you get your wheels aligned to get rid of camber angle problems, worn ball joints, etc. that may damage the springs.
Always take your car for a wheel balancing and checkup after about 5000 miles or twice yearly.
Proper Tire Inflation
Underinflated or overinflated tires cause inner tire wear due to the inability of the sidewall to force the tires to contact the road properly.
Endeavor to check the tire pressures and inflate when regularly. If overinflated, deflate the tires to prevent faster wear from the inside.
Regular Wheel Balancing
100% of the mechanics report that the average vehicle owner brings their cars for tore inspection only after they observe wears on them. It is a terrific practice, and you risk buying new tires too often.
Make sure to keep in touch with the mechanic timely and run wheel balancing at least once every 2 years.
It is also advisable to take new tires for balancing after installations on your vehicle; it protects it from early wear.
Fix or Replace Damaged Suspension Components
Damaged suspension components on your car encourage faster wear on the inside of the tire. It can also slow down the vehicle speed which burns more gas. Meanwhile, learn ways to improve mileage in a petrol car.
Note that leaving faulty suspension components unfixed results in irreparable repair.
Check Tire Tread Depth Regularly
Perform routine checks on tire tread depth regularly. New tires from the manufacturer have good tread depth, but as time goes on, the thread gets thinner. Make sure to check whether your tires are below the minimum tread depth.
Why Do Rear Tires Wear on the Inside?
Rear tires can wear on the inside due to multiple reasons including misaligned wheels (too much toe-out) for a long time, camber angle problems, worn-out ball bearings and joints, broken suspension components.
What Tire Wears Faster, Left or Right?
From observations, the front tires tend to wear faster than the rear tires, particularly the left front tire. The reason is that the front tires are responsible for heavier loads and steering transmissions during right-hand bends.
In essence, the front tire wears faster because of the excessive pressure on the tire.
When Should Tires be Replaced?
Tires that are 10 years old should be replaced.
Tires tend to wear out over long time usage and should be replaced upon identifying damage.
Moreover, you can verify the age of the tire by examining the marks on the tire sidewall following the “DOT” symbol. If you are buying a used tire, avoid tires older than 10 years.
Do Tires Expire?
Yes, tires expire! Car tires, like every usable commodity, have an expiry date. Tires have expiration dates typically stipulated at six years from the date of manufacturing.
When you identify the cause of your vehicle’s inner tire wear, contact a professional for tire replacement or repairs.
