How to Mount a Tire: A Step-by-Step Guide

Mounting a tire correctly is a process that can save us money and ensure our safety on the road. When we decide to tackle tire mounting, we give ourselves the ability to switch out tires at our convenience.

The importance of this task cannot be overstated—correctly mounted tires contribute to optimal tire pressure maintenance, vehicle handling, and long-term durability of both the new tires and the wheels they’re fitted on.

For many of us, mounting a tire can seem daunting, but with the right tools and techniques, it is entirely manageable.

Across countless mechanic shops, the procedure remains consistent: we must ensure that the tire is correctly aligned on the wheel, the bead is properly seated, and the tire is inflated to the right pressure.

Handling these steps with precision enhances the tire’s contact with the road and the overall driving experience.

Knowing the techniques for tire mounting can serve us during emergency tire changes or when we want to upgrade to new tires without seeking professional help.

Not only does it give us the satisfaction of handling the job on our own, it also contributes to cost savings over time.

It’s a skill worth acquiring, whether we are enthusiasts looking to expand our automotive knowledge or seeking practical ways to maintain our vehicles with efficiency.

Preparing for Tire Mounting

Before we begin mounting a tire, it’s crucial to have all the necessary tools and materials at hand and to ensure that safety protocols are followed.

Proper preparation will lead to a smoother and safer tire mounting process.

Tools and Materials

Essential Tools:

  • Tire lubricant or soapy water
  • Valve core removal tool
  • Mounting bar or pry bar
  • Tire gauge
  • Compressed air canister or air compressor


  • New valve stems (if required)
  • Replacement tire

We start with the collection of tools necessary for the job.

Lubricant or soapy water is essential for easing the tire onto the rim.

A valve core removal tool will let us deflate the old tire and prepare the new one.

A mounting bar or pry bar is used to work the tire onto the wheel.

The tire gauge will ensure appropriate inflation, and the air compressor is vital for seating the tire beads.

Safety Measures

Always Prioritize Safety

When mounting a tire, we must not overlook safety:

Safety Gear:

  • Eye protection
  • Sturdy gloves

Safe Practices:

  • Ensure the wheel is securely fastened on a flat, stable surface.
  • Verify the work area is free of hazards.
  • Be cautious when inflating the tire to recommended PSI to avoid overinflation.

Using eye protection is non-negotiable to shield our eyes from any debris or accidental spray of lubricant.

Gloves protect our hands during the mounting process and help us grip the tools and tire firmly.

Working on a flat, stable surface prevents the wheel from moving unpredictably, thus avoiding potential injuries and ensuring a proper mount.

Mounting the Tire

When we mount a tire, it’s crucial to work methodically to ensure the tire seats correctly on the rim. It involves removing the old tire from the wheel and installing a new one using the correct techniques and tools.

Removing the Old Tire

To begin with, we ensure that the tire is completely deflated.

We remove the valve stem core to let out the air and then place the tire onto the tire changer.

Using the tire machine’s bead breaker, we apply force to the tire sidewall near the rim flange, effectively loosening the tire beads from the rim.

We need to be careful not to damage the wheel or the tire during this process. The use of a tire machine simplifies the process and helps prevent any accidental damage.

Installing the New Tire

After removing the old tire, we prepare the new tire for mounting.

This includes inspecting the tire beads and applying a liberal amount of tire lubricant to make the installation process smoother.

We ensure the bead is seated properly against the rim and then use the tire machine to roll the top bead over the rim flange, followed by the bottom bead.

It’s important to ensure that the tire is aligned properly before inflating it to the recommended pressure. This helps in avoiding any balance issues or tire damage.

We take great care to avoid using excessive force when installing the new tire, as this can damage the bead or the wheel.

Once mounted, we inflate the tire, making sure that both tire beads seat correctly against the rim.

Proper inflation ensures the tire is ready for balancing and subsequent use.

Balancing and Inflation

When we mount a tire, ensuring it is properly balanced and inflated is crucial for vehicle safety and performance. Incorrect pressure or balance can lead to tire wear and potential vehicular hazards.

Inflating the New Tire

First, we’ll address inflating the new tire. Proper inflation is key to tire performance and longevity.

We begin by checking the manufacturer’s recommended tire pressure level, usually found in the vehicle’s manual or on a sticker inside the door jamb.

Steps to Inflate the Tire:

  • Remove the valve cap from the tire’s valve stem.
  • Attach the air compressor hose to the valve stem.
  • Turn on the compressor and fill the tire to the recommended pressure.
  • Use a reliable tire pressure gauge to check the pressure.
  • Replace the valve cap securely once the tire is properly inflated.

Tire Balancing

Next is balancing, which ensures that the weight of the wheel and tire is evenly distributed around the axle. Without proper balancing, wheels can wobble or bounce, leading to tire wear, vibration, and reduced traction.

Balancing should always be done when mounting new tires, after a tire repair, or when you notice symptoms of unbalance.

Wheel/Tire Assembly Mounted on a balancing machine
Measurement Machine spins the assembly to determine imbalance
Correction Addition of weights to the rim for balance

We use a specialized balancing machine to identify imbalances and to apply counterweights properly.

By following these steps, we can help ensure our vehicle’s wheels are well-balanced, providing a smoother ride and optimal tire life.

Maintenance and Safety

Proper tire maintenance and a rigorous safety protocol are crucial to ensure the longevity and performance of your vehicle’s wheels.

We will cover how to inspect your tires regularly for any potential issues and understand the vehicle dynamics to maintain tire welfare.

Regular Inspection and Maintenance

We should all adhere to a consistent schedule to examine our tires for damage, rust, and any signs of wear. This includes checking:

• Tread Depth: Our tires should have at least 1/16 inch (1.6mm) of tread. A penny test can be a quick method to check this.

Place a penny into several tread grooves across the tire. If part of Lincoln’s head is always covered by the tread, you have more than 1/16 inch of tread depth remaining.

• Sidewall Integrity: Look out for cuts, cracks, or bulges on the sidewalls, as they can lead to failures.

• Air Pressure: Maintaining the correct air pressure is essential. Incorrect pressure can lead to unbalanced tire wear and can drastically affect handling characteristics.

• Wheel Assembly: Make sure that lug nuts are tightened to the vehicle manufacturer’s recommended torque and that your wheels are properly aligned.

Understanding Vehicle Dynamics

Understanding how a tire’s condition affects vehicle dynamics is paramount. A well-maintained tire provides the base for how our vehicle moves and responds on the road.

Unbalance or misalignment can lead to a compromised angle of contact with the road, affecting traction and possibly causing unpredictable vehicle behavior.

We need to ensure that tires are rotated as recommended by the vehicle manufacturer. This not only promotes even wear but helps retain the tire’s structural integrity, ensuring safe and reliable handling characteristics.
