If you’re planning to open your own tire service shop, it's critical that you know how to mount a tire properly. Using incorrect mounting techniques can seriously damage the tires and lead to a tire blowout.
Mastering tire mounting also ensures that your customers will be satisfied with your service, even the ones who are finicky with how they want their wheels handled. You’ll eventually gain loyal customers who support and even endorse your shop to people they know.
With that, below are four common mounting mistakes to avoid when using an automatic tire changer.
1.Mounting reverse mount wheels the wrong way
Reverse mount wheels have become quite popular these days. They’re commonly used for lowered cars since the low profile can damage the tire beads.
The first step to handling reverse mount wheels correctly is to learn how to identify them. They have a drop section in the rim profile and a little ridge going around the outer lip that makes it thicker than the inside lip.
To properly mount this type of wheel, all you need to do is fit the rim from the back. You can also use a reverse mount adaptor so you don't accidentally scrape the wheel's surface. Scratches on the chrome can quickly result in rust. Use jaw protection when clamping the tire to prevent abrasions.
2. Placing the bead breaker incorrectly
One of the most common causes of tire damage during the changing process is the misplacement of the bead on the mount head. You might damage the sidewall plies if you don’t place the bead breaker close enough to the tire. Clamping it too tightly, however, can scratch the wheel.
3. Not seeing the TPMS
You also need to know how to recognize the tire pressure monitoring system (TPMS), so you don't damage it when you mount the tire. A tire tech who isn’t paying attention might accidentally shovel the TPMS sensor when mounting the tire, which can snap off the valve system and break the tire bead inward.
Luckily, TPMS sensors are easy to spot; you just have to remember to check for them. Most sensors are connected to a valve stem and sit along the tire’s rim flange. They don’t lay flat against the wheel, which means you can easily see them. Just be careful not to push or crush the sensor when mounting the tire.
4. Not using the right amount of lubricant
You need to use lubricant both when mounting and dismounting tires. Be sure to apply enough lubricant so that the casing slides on smoothly onto the rim. You can’t put too much, though, because it might cause vibration problems and tire-to-wheel slippage.
Apply the lube on the bead seat, the inner toe area of the tire bead, and the balcony of the wheel drop center.
Getting the right auto tire changer can help you avoid these mounting mistakes. Make sure to get one with features like a tilt mechanism, large turntable, and reverse mount adaptor. These accessories make it easier for you to mount and dismount tires properly and avoid damaging them.
