Not all tire changes are alike
Tire changes are a standard service at any automotive repair facility.
As simple of a process as it may seem, some tires require further attention.
Two prime examples of this are low-profile tires and run-flat tires.
It can be easy to assume that the stock wheels on your vehicle wouldn't
have these installed. But, that is not the case. Modern trends have encouraged
inclusion of larger wheels with lower profile tires on many of the sporty trim
packages. This creates a need for additional care and effort into the removal and
installation process. Today we have a good example of this, so let's down to the
nitty-gritty!
Here you will find a gorgeous 2021 BMW M850i xDrive. 523 horsepower and
553lbs of glorious torque only a pedal tap away? Yes, please! But, solid power
needs solid delivery. And, with an all wheel drive system such as this with BMW's
xDrive... it is even more crucial. Meanwhile, back to the job at hand.
The vehicle experienced a flat tire. Due to this, it was taken to the closest
repair shop and the tire was plugged. Be warned! This is not correct. This car
came with run-flat tires.
These tires in particular were designed that once punctured, they can
drive 50 miles (while safely driving under 50 mph) without tire pressure. This
is to allow you to drive to a repair facility. Then, they must be replaced. They
are not designed to be plugged. Once punctured, the tire composition is
designed only to withstand a certain distance. The structural strength of the
tire is compromised and will create risk to drive thereafter.
So, we have it here today for replacement. Thus bringing us to the removal
and installation process. Since this car is quite sporty, it also features large 20"
wheels with low profile tires. So we are looking at a run-flat low-profile tire
replacement.
How does this affect the process? Well, the durable kevlar composition of
the run-flat is much less workable in the process. Then, add to it being low-profile
and you have even further increased the difficulty in the removal & installation
process.
Overall, when completing a service such as this, here are some core
factors you must consider before getting started:
TPMS sensor location
Front or Reverse Mount Wheels
Finish Present on Wheel
Size of Wheel
Tire Composition/Type of Tire
Pressure Rating of Tire
So, be aware of what tires you have on your vehicle. Or, as a servicing
technician, be aware of what tires are installed on the vehicle you are about
to put hands on. Awareness is crucial to both complete the task and minimize
issues/damage to the vehicle.
