BMW F20 F21 1 Series Wheel & Tire Fitment Guide

Vehicles Covered in this Guide All years and models of 1 series Hatchbacks (5 door hatch: F20, 3 door hatch: F21). Our fitment testing has focused on the Coupe and convertible models available in the US, but international customers have provided feedback that the wheel and tire fitments carry over to the hatchback chassis.

Chassis Introduction The F2X's perfect size and weight distribution make it one of the most desirable models in BMW's modern lineup. Although the platform has somewhat specific width and offset requirements, they nearly mirror those of the previous 1-Series, meaning we already have many different fitment options available.

For those considering 17" wheels:

Brake clearance is tight with certain stock brake calipers when running 17" wheels on the F22 chassis. The optional brake packages with 370mm front rotors available on some cars will not clear 17" wheels. Cars with 345mm rear rotors will have extremely tight clearances with the vibration dampeners on the ends of the brake pads and caliper-to-barrel clearance as well. 17" wheels will clear the calipers themselves, but debris may be caught between the rear brake calipers and the barrel of the wheels which may cause scratching on both components over time.

Caliper color alone is not a viable way of identifying which brakes you have! If you are unsure which brake package your car is equipped with, you can review Bimmerworld's technical article here for information on the various brake packages by model.

Performance Street and Track Wheel Fitment

Wider fitments for enhanced performance

  • Blue BMW 1 Series - SM-10 in Custom Finish
    BMW 1 Series F20 F21
  • White BMW 1 Series - ARC-8 in Anthracite
    BMW 1 Series F20 F21
  • Blue BMW 1 Series - SM-10 in Satin Black
    BMW 1 Series F20 F21

Because the 2-Series fitment requirements are so specific, we only offer a limited number of high-offset wheel options which can be used for nearly all types of street, track or race driving. They work well with anything from all-season tires to all-out racing slicks.

Square Setups Recommended for most types of street and performance driving. Allows proper front-to-rear tire rotation to extend tire life & improve handling balance.

Additional Resources

Concavity & Face Profiles

Each of our wheel designs is available in two or three different levels of concavity, which we call Profiles. The Profile is dictated by the width and offset, meaning wide lower-offset wheels will have more concavity, while narrow higher-offset wheels will have less concavity.

Identifying Suspension Types

If you’re using coilovers, see the image below to identify which type of coilover spring you have, as it may effect your wheel fitment.

Aftermarket 2-Series Suspensions Known To Reduce Inner Clearance (includes but not limited to):

  • Bilstein PSS9 & PSS10
  • KW Height-Adjustable Spring (HAS) kit
  • KW Variants
  • KW Clubsports
  • Öhlins Road & Track

About Camber Plates

Adjustable camber plates do more than just aid in wide wheel and tire fitment. They provide increased grip and reduced tire wear by spreading the load evenly during cornering. Learn more in our blog article, The Positives of Negative Camber.
