Technical characteristics of the steel rim

The presented spare wheel is based on a steel rim, which ensures high resistance to typical operational loads, including road irregularities and changing weather conditions. The rim design is optimized for compatibility with the SUV's chassis, ensuring proper suspension geometry and driving stability after the spare wheel is installed.

The bolt pattern and diameter of the mounting holes are adapted to the typical hub layout in Mercedes W166 models, which facilitates installation in roadside conditions. The rim's parameters allow for seamless seating on the hub and proper tightening of the bolts, without the risk of improper contact with the mounting surface.

Goodyear R19 tyre as emergency equipment

The wheel is equipped with a Goodyear tyre with a profiled construction, selected for use as a spare. The tyre width has been chosen to provide a balance between driving stability and compact wheel dimensions, which makes it easier to store in the luggage compartment.

The tyre tread is designed for predictable behavior on typical road surfaces, which is particularly important in emergency situations. Such a spare wheel set allows for safe continuation of the journey to a service station or destination, while maintaining reasonable speeds and a cautious driving style.

Purpose and application in Mercedes W166

The Mercedes W166 spare wheel is intended as an emergency component, designed for short-term use after one of the main wheels is damaged. Thanks to the matching of rim parameters to the characteristics of the SUV's axle and suspension, the correct operation of assistance systems, such as ABS or traction control, is maintained within the scope intended for spare tyres.

The steel rim withstands long-term storage in the trunk well and is less susceptible to minor mechanical damage than alloy wheels. It is a practical choice for drivers who expect a functional, ready-to-use set without the need for additional configuration or retrofitting.

Why choose a used Mercedes spare wheel

Choosing a used Mercedes spare wheel is a reasonable cost-effective solution while maintaining the manufacturer's original specifications. You receive a component from the same design line as the factory equipment, which translates into a proper fit for the hub, wheel arch, and vehicle safety systems.

The steel rim combined with a branded Goodyear tyre ensures predictable vehicle behavior in an emergency situation, while not requiring complicated service before installation. It is a practical choice for drivers who want to increase their SUV's mobility without investing in a new, full set of wheels.
