Quick answers about UK tyre fitment, MOT rules and seasonal options.
Where should I check the original tyre size for my BAC Mono?
Look in three places: (1) the sidewall of the existing tyre, (2) the placard inside the driver's door frame, and (3) the vehicle handbook. The driver's door placard is the official OEM specification, and the sidewall confirms what's fitted now.
What's different about the 2021-present Mono compared with other generations?
This is the 2021-present generation of the BAC Mono. Earlier and later generations use different platforms, wheel sizes and tyre fitments, so always match your specific year to the correct generation page.
Are OEM tyres still fitted to new BAC Mono cars?
New UK BAC Mono cars leave the factory with original-equipment (OEM) tyres specified by BAC. When replacing, you can stay on the same OEM brand or move to an alternative provided the size, load index and speed rating match.
What tyre size does the 2021-present BAC Mono use?
Common UK factory fitments for the 2021-present BAC Mono include 205/40 R17, 245/35 R18. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.
Are run-flat tyres needed on the 2021-present BAC Mono?
Most 2021-present BAC Mono cars were supplied with conventional tyres and a spare or repair kit. Only fit run-flats if your specific car was originally specified with them and has tyre pressure monitoring.
