Look at the tyre sidewall for the size code (for example, 195/55 R15), or check your owner’s manual and the sticker inside the driver’s door area. If you use the registration search, it will usually return the factory fit, but confirm it matches what is fitted to the car.

It should suggest tyres that meet the required specification for the vehicle record, but it is still important to match the load index and speed rating shown on your current tyres or handbook. If your 306 has been modified with different wheels, manual size search can be more accurate.

In the UK, the legal minimum is 1.6mm across the central three quarters of the tread around the full circumference. Many drivers replace earlier (often around 3mm) for better wet grip and shorter stopping distances.

All-season tyres can be a strong option if you want one set to handle wet roads and colder temperatures without swapping tyres twice a year. For best balance and stability, fit the same type on all four wheels.

After selecting your tyres, you choose a nearby fitting partner and book an appointment time that suits you. The tyres are delivered to the garage, and you arrive for fitting on the day, with pricing and booking confirmed during checkout.
