BMW 4 Series Spare Tire Fitment Guide
The BMW 4 Series used 5x112 mm and 5x120 mm bolt pattern variations from 2014 to 2026 along with tire diameters ranging from 25.9" to 27.0" 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 BMW 4 Series years and options. In this case, 125/80R18, 135/80R18 and 145/60R20 spare tire sizes are used to avoid vehicle components while closely matching the original tire size diameters. We've provided a breakdown by vehicle generation and model specifics to help you find the correct BMW 4 Series spare tire.
2021-2026 BMW 4 Series Coupe/Convertible Spare Tires
This generation of the BMW 4 Series Coupe/Convertible began in 2021 and is still the current model being produced. There were multiple versions manufactured in this year range and have specific spare tire and wheel solutions for each one. The Coupe and Convertible M4 models include CS and Ceramic Brake versions. The Standard Coupe/Convertible, M Sport/Performance Brake, and M440i Coupe/Convertible models are listed individually. The xDrive option does not change the recommended spare tire. (Listings include 420i, 430i, etc.)
There was a facelift redesign in 2025 that altered the appearance but it had no impact on the spare tire fitment specifically.
