Only One Tire Is Wearing on The Inside? Here’s Why & How to Fix It

only one tire is wearing on the inside

Have you noticed that only the inside edge of one tire is showing premature wear? It does not only invite early tire replacement costs but also vehicle handling and safety issues.

Spotting excessive tread wear on just the inner edge of one tire is a clear sign of a problem that needs attention. Inner tire wear can have various causes and creates unsafe handling issues. 

In this blog post, we will go in-depth to examine the common reasons for inner tire wear and the steps to fix it.

Watch for these key indicators that show a tire is wearing abnormally on the inside:

  • Visible bald sections or smoothness on the inner tread edge and shoulder
  • Feathering – small cracks and grooves – developing in the inner tread rubber
  • Wavy cupping wear patterns forming on the inner tire tread knobs
  • The exposed tire cord is visible on the inner edge as tread rubber erodes

These symptoms typically only appear on one tire if something is causing that individual tire to wear faster on the inside. 

Compare wear patterns across all tires to spot this uneven tire wear. Catching it early allows addressing the root issue before further damage.

Causes of only one tire wearing on the inside

wheel alignment

A variety of mechanical issues can lead to premature wear isolated on the inner tread surface:

Wheel alignment issues

Wheel alignment outside of specifications is the most common cause of inner tire wear. The angle of the wheels and axles gradually shifts out of alignment over months of driving. 

Specific alignment problems that wear the inner tread are:

  • Excessive Negative Camber: Negative camber means the wheels tilt slightly inwards at the top when viewed from the front. Too much negative camber makes the tires roll on their inner edge, wearing that rubber prematurely. This over-cambered angle can result from worn suspension parts or improper alignment settings.
  • Toe-In misalignment: When toe-in is outside specs and the front wheels point slightly inward, the tires drag and skid during turns. This scrubs away the inner tread.
  • Overcamber on rear wheels: Too much negative camber in the rear also concentrates force on the inner tread as weight shifts rearward during acceleration.

Misalignment needs to be identified and corrected to stop abnormal innerwear.

Worn suspension components

Parts like ball joints, control arms, struts, shocks, and tie rods affect wheel angles. As these components wear out, they can create misalignment leading to inner tire wear over time. If they are excessively loose or damaged, new replacement parts may be required.

Aggressive driving habits

Sharp turning, fast acceleration, sudden braking, and hitting curbs or potholes put high stress on tires. The inner tread and sidewall take the most abuse from such rough driving. Inner edge wear results. Adopting a smoother driving style can help tires wear evenly.

Improper inflation pressure

Incorrect tire pressure concentrates force unevenly across the tread:

  • Over-inflation focuses pressure on the center, wearing that part of the tread first.
  • Under-inflation allows more force along the outer tread edges as the tire flattens, increasing wear on those areas.

Maintaining the vehicle manufacturer’s recommended inflation level helps prevent uneven wear.

Lack of regular tire rotation

tire replacement

Not rotating tires every 5,000-8,000 miles prevents wear from distributing evenly across the tread. Without rotation, the inner edge wears faster from bearing the brunt of friction and heat buildup. 

Rotating evens out wear as different tread sections face the friction zone.

In most cases, a combination of these factors contributes to premature inner edge wear. 

A qualified technician can diagnose the specific causes in your scenario and recommend solutions.

Dangerous of driving with only one inner tire wear

It’s hazardous to keep driving with excessive inner tire wear, including:

  • Reduced traction and stability: The loss of inner tread knobs lessens grip when cornering, braking, and accelerating. This makes the vehicle more prone to skidding and sliding.
  • Increased risk of blowouts: As protective rubber wears down, the sidewall cord is exposed. Hits to the weakened sidewall are more likely to cause ruptures or tire blowouts.
  • Steering wheel vibration: Uneven tread height resulting from inner wear creates an imbalance. This imbalance can create vibrations and shimmying felt in the steering wheel.
  • Uneven braking: With less tread depth on the inside, braking traction is reduced on that part of the tire’s contact patch. This can make braking distances longer and unpredictable.

Excess inner wear must be fixed before a tire becomes dangerously compromised.

How to fix inner tire wear


Several actions can correct inner tire wear and its underlying causes like fixing those issues we talked about earlier:

  • Wheel alignment adjustment: Have an alignment shop measure and adjust front and rear wheel alignment to vehicle specifications. This straightens any misalignment causing innerwear.
  • Suspension repairs: Inspect ball joints, struts, control arms, bushings, bearings, and tie rods. Replace any excessively worn parts enabling proper wheel angles.
  • Tire rotation and inflation: Ensure tires are inflated to the recommended PSI and rotate them every 5,000-8,000 miles. This prevents uneven wear from developing.
  • Smoother driving: Ease up on aggressive turning, rapid acceleration, sudden braking, and curbing wheels. Give tires a break from forces causing uneven wear.
  • Professional diagnostic: Have a certified mechanic inspect the full suspension and alignment. They can pinpoint the causes of inner wear and suggest repair options.
  • Tire replacement: If wear is too severe, new tires may be required to restore safe handling.

Correcting underlying issues improves safety by allowing even tread wear.

Preventing premature inner tire wear

check tire pressure and inflate

You can minimize inner tire wear through:

  • Regular tire rotations: Rotate every 5,000 miles or at oil changes to distribute wear evenly.
  • Proper inflation: Check pressures monthly and keep tires inflated to recommended PSI. Under/over-inflation causes uneven wear.
  • Wheel alignment checks: Inspect alignment every 6 months or 5,000 miles to catch issues early.
  • Suspension inspection: Look for signs of worn parts needing replacement to maintain proper wheel angles.
  • Smoother driving habits: Take turns and accelerate/brake gradually. Avoid potholes and curbs that stress tires.
  • Tire type: Performance tires with soft compounds wear faster on the inner shoulders than touring tires. Consider tire construction for your needs.

Here is the complete guide to help you with tire rotation.

Being proactive with maintenance helps tires last their full lifespan.

When to replace a tire with inner wear

If inner tire wear exhibits any of these signs, replacement is likely needed:

  • Cord or belts are visible under the tread due to extensive inner wear
  • The tire fails the penny test for minimum safe tread depth
  • Uneven inner wear is too severe to be remedied through rotation or alignment

Driving on dangerously worn tires risks blowouts and loss of control. Replace them promptly.

Correcting inner tire wear protects your safety

Noticing premature wear isolated to the inner tread requires identifying the underlying cause. Proper wheel alignment, suspension service, tire rotation, and avoiding curbs will resolve this issue. With attentive maintenance, your tires will wear evenly and last longer, providing safe handling and peace of mind.
