Can I downsize from larger wheels on my Peugeot 308?

Some trims of the 308 can be downsized to a smaller OEM-approved wheel, which often gives better ride and lower tyre cost. Peugeot usually publishes approved alternative sizes — check the handbook before changing wheel size.

What tyre size does the 2021-present Peugeot 308 use?

Common UK factory fitments for the 2021-present Peugeot 308 include 205/55 R16, 225/45 R17, 225/40 R18. The exact size depends on the wheel and trim ordered — always confirm on your tyre sidewall before fitting.

What wet grip should I look for on the Peugeot 308?

For UK driving conditions, prioritise an EU tyre label wet-grip rating of A or B. Wet grip directly affects braking distance — the gap between A and E ratings can be more than a car length at 50 mph.

Are run-flat tyres needed on the 2021-present Peugeot 308?

Most 2021-present Peugeot 308 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.

Where should I check the original tyre size for my Peugeot 308?

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.
