Mercedes-Benz GLB-Class Spare Tire Fitment Guide
The Mercedes-Benz GLB-Class used a 5x112 mm bolt pattern for all models from 2020 to 2026 along with tire diameters ranging from 28.2" to 28.3" tall. Using a temporary compact spare tire with a diameter close to the standard tire has many benefits, especially for modern vehicles with larger brake calipers and anti-lock brakes or traction control systems.
The tire diameter and the wheel diameter clearance have been taken into account for the specific Mercedes-Benz GLB-Class years and options. In this case, a 145/85R18 temporary spare tire is the recommendation for all applications. We've provided a breakdown by vehicle generation and model specifics to help you find the correct Mercedes-Benz GLB-Class spare tire.
2020-2026 Mercedes-Benz GLB-Class Spare Tires
This generation of the Mercedes-Benz GLB-Class began in 2020 and is still the current model being produced. All the models (GLB 200, GLB 220, GLB 250, etc.) for these years use the same spare tire and wheel solution including 4MATIC versions.
Although there was a facelift redesign introduced in 2024, the spare tire requirements remained the same.
