Sudden tire damage on a busy suburban highway requires the vehicle to stop immediately on the side of the road. The driver must turn on the alarm system, wear a reflective vest and place an emergency stop sign at a safe distance.
Self-installation of a spare disc saves the driver time and completely eliminates the cost of calling the evacuation service. The technical procedure requires a serviceable standard jack, a cylinder wrench, and a clear understanding of the wheel hub locking algorithm.
Body locking and tool preparation
Before starting the repair work, the driver parks the car on the most level area of asphalt, avoiding soft ground and slopes. The vehicle is locked with the parking brake, and the automatic transmission selector switches to parking mode to lock the transmission.
Under the wheels located on the opposite side of the punctured tire, anti-rollback stops or massive stones are installed. This safety measure prevents accidental displacement of the heavy body when the damaged wheel is detached from the road surface.
The preparatory stage before lifting the body includes:
- removing the spare wheel and tool kit from the trunk;
- cleaning of wheel bolts from adhering dirt with a metal brush;
- Loosen the fasteners by half a turn before lifting.
It is necessary to loosen the tight bolts on a stationary car when the tire is rigidly attached to the asphalt and prevents the hub from turning. The driver uses leg strength or a special extension tube for the lever if the threaded connections are stuck due to corrosion.
A standard screw or hydraulic jack is installed strictly under the reinforced edge of the threshold stiffness, marked with a factory stamp. An error in the positioning of the lifting mechanism will inevitably lead to deformation of the thin metal bottom or plastic linings.
Removing the damaged tire and working with the jack
The rotation of the jack handle smoothly lifts the car body until the flat tire is completely lifted off the ground. The working gap between the tread and the asphalt should be about five centimeters to provide free space for installing the inflated spare tire.
After securely locking the vehicle at the desired height, the driver completely unscrews the loose wheel bolts. The dismantled wheel is carefully removed from the guide pins and temporarily placed under the threshold of the car as additional insurance in case of a fall from the jack.
The algorithm for safely removing a punctured disk includes:
- folding the unscrewed bolts into a clean container to avoid loss;
- careful loosening of the stuck disc by palm strikes on the rubber;
- visual inspection of the brake caliper and hoses for damage.
Installing a full-size spare wheel or a narrow rolling disc requires precise alignment of the threaded mounting holes on the hub. The driver lifts the heavy wheel with his feet or uses the mounting blade as a lever to center the heavy cast disc.
The wheel bolts are manually tapped into several turns to prevent damage to the thread when the fastener is skewed. The use of a cylinder wrench at this stage is allowed only for light tightening of joints without significant physical effort.
Installing the spare wheel and checking the pressure
The bolts are pre-tightened criss-crosswise to ensure a uniform fit of the metal disc to the landing plane of the hub. The car smoothly descends to the ground by releasing pressure in the jack or by rotating the screw mechanism back.
The final broaching of the fasteners is performed on a fully lowered vehicle using the driver's body weight. The correct tightening force ensures that the wheel is securely locked at speed, preventing dangerous steering vibrations and the cutting of threaded pins.
The pressure gauge of the portable compressor allows you to check the pressure in the installed spare tire, which often drops over the years of storage in the trunk. The driver adjusts the pumping parameters to the factory settings indicated on the information plate in the driver's door opening.
Operating a car with a narrow spare wheel requires strict compliance with the speed limit up to 80 km/ h and avoiding sudden maneuvers. The damaged tire is sent to the luggage compartment for subsequent transportation to the nearest tire repair and tread repair.
