The BMW 4 Series is one of the most stylish and performance-focused coupes and convertibles in BMW’s lineup. From the F32 generation launched in 2013 to the latest G22 models, each version brought new design and fitment updates. Understanding proper wheel and tire fitment is crucial to maintaining handling balance and avoiding clearance issues. This guide breaks down wheel specs, bolt patterns, offsets, and hub bores for all BMW 4 Series generations — including both OEM and aftermarket setups for the F32, F33, F36, G22, G23, and G26 models.
Understanding Wheel Fitment
Wheel fitment determines how your wheels sit inside the wheel arches and directly affects performance, safety, and aesthetics. Key measurements include bolt pattern (PCD), offset (ET), and hub bore. The bolt pattern ensures correct mounting, the offset defines how far the wheel sticks out or tucks in, and the hub bore centers the wheel. For BMW 4 Series models, you’ll see 5×120 and 5×112 bolt patterns, depending on generation, with hub bores of 72.6 mm or 66.6 mm. Proper fitment keeps the steering smooth, avoids vibrations, and allows you to run OEM or aftermarket wheels confidently.
BMW 4 Series Fitment Overview
The BMW 4 Series shares many components with the 3 Series, but wheel fitment varies across generations. Early models (2013–2020) used the traditional 5×120 bolt pattern with a 72.6 mm hub bore, while newer G-series models (2020–2026) switched to 5×112 and a 66.6 mm hub bore. Offsets typically range from ET25 to ET45, depending on trim level. OEM wheel sizes start at 17” and go up to 21” for M Performance versions. When upgrading, aftermarket options like 19×8.5 or 20×10 setups offer a balanced stance without affecting handling or comfort, provided offset and tire width are chosen correctly.
BMW 4 Series F32/F33/F36 [2013–2020]
The first-generation BMW 4 Series (F32 Coupe, F33 Convertible, and F36 Gran Coupe) was based on the F30 3 Series chassis. These models use a 5×120 bolt pattern, 72.6 mm hub bore, and offsets between ET30–ET45. OEM wheel sizes range from 17×7.5 to 19×8.5 inches, with tires from 225/45R17 to 255/35R19. Aftermarket options commonly include 18×8.5 front and 19×9.5 rear for a staggered look.
F32/F33 (Pre-LCI) [2013–2017]
The pre-facelift F32/F33 models feature the classic BMW fitment of 5×120 PCD, 72.6 mm hub bore, and offsets between ET34–ET45. Standard wheels came in 17–19 inches with tire combinations like 225/45R18 front and 255/40R18 rear. Enthusiasts often fit 19×8.5 ET35 or 19×9.5 ET40 aftermarket wheels for a sportier stance without rubbing issues.

G26 Gran Coupe
The G26 Gran Coupe uses the same 5×112 bolt pattern and 66.6 mm hub bore but needs careful offset selection due to its longer wheelbase. OEM wheels run 18×8 to 20×9, with ET30–ET40 offsets. Popular aftermarket setups include 19×8.5 ET35 front and 19×9.5 ET38 rear, paired with 235/40R19 and 265/35R19 tires, offering both elegance and stability.
Recommended Aftermarket Fitments
Upgrading wheels enhances both looks and performance. For the F-Series, 19×8.5 front and 19×9.5 rear (ET35–ET40) with 225/40R19 & 255/35R19 tires provide a clean fit. For the G-Series, 20×9 ET30 front and 20×10 ET35 rear with 245/35R20 & 275/30R20 tires give an aggressive stance. Always ensure hub rings match the 72.6 mm or 66.6 mm hub bore, and offsets keep clearance within factory tolerances.
Conclusion
The BMW 4 Series has evolved from the F32’s classic stance to the modern G22’s bold proportions, with fitment specs changing along the way. Knowing your generation’s bolt pattern, hub bore, offset, and OEM wheel size ensures perfect wheel upgrades without compromising safety. Whether you’re chasing a flush street fitment or track-ready setup, matching the right specs guarantees your BMW 4 Series performs and looks its best.
