Find Tyres for 2021-present BMW i4 (G26)
Year-specific tyre fitment data for the 2021-present BMW i4. Confirm size, load and speed rating before fitting.
About this generation
As an EV, the BMW i4 carries more weight than a comparable petrol car and delivers torque instantly — both factors that make EV-specific tyres a sensible choice. Original equipment was typically EV-rated.
The current-generation BMW i4 (2021-present) is sold in the UK with a small set of factory tyre sizes per trim. Replacement tyres should match the size, load index and speed rating of what came on your specific car.
Chassis code: G26. Use the chassis code to confirm you have the right generation when ordering tyres.
Common factory tyre sizes

BMW works with tyre makers to develop OEM-marked versions for the i4, tuned for the car's suspension calibration. Star, MO, AO or J markings indicate manufacturer-approved tyres.
Wet grip is the most relevant EU label rating for UK driving. On the i4, prioritise wet grip A or B for shorter braking in rain.

Frequently asked questions
Quick answers about UK tyre fitment, MOT rules and seasonal options.
Can I downsize from larger wheels on my BMW i4?
Some trims of the i4 can be downsized to a smaller OEM-approved wheel, which often gives better ride and lower tyre cost. BMW usually publishes approved alternative sizes — check the handbook before changing wheel size.
What should BMW i4 drivers know about UK potholes?
UK road conditions are tough on tyres. Check sidewall bulges, cuts and tread depth regularly — especially on the inside edge, which often wears unevenly. A 20p coin gives a quick legal-tread check.
What's different about the 2021-present i4 compared with other generations?
This is the 2021-present generation of the BMW i4. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
What tyre size does the 2021-present BMW i4 use?
Common UK factory fitments for the 2021-present BMW i4 include 225/50 R18, 245/45 R18, 245/40 R19, 255/35 R19. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Should I fit EV-specific tyres to the BMW i4?
EV-specific tyres are designed for the extra weight and instant torque of electric drivetrains. Many 2021-present BMW i4 cars were supplied with EV-rated tyres (often labelled "EV", "Elect" or with a snowflake-and-bolt). Sticking with EV-rated rubber tends to preserve range and tread life.
