Yes. Entering your UK registration pulls up tyres that match your Citroen C2's fitment, which helps avoid ordering the wrong size.
Check the tyre sidewall for a code like 195/55 R15. Enter that size into the manual search to see tyres that fit.
You can book fitting at a local garage during checkout to have the tyres fitted professionally. Available delivery and fitting options can vary by tyre and location.
In the UK, it is best practice to fit the same tyre brand and pattern on the same axle. Mixing can affect handling and braking, so match pairs on each axle where possible.
The UK legal minimum is 1.6mm across the central three-quarters of the tread around the full circumference. Many drivers replace tyres earlier, especially if wet grip is reduced or the tread is close to the limit.
