Use the registration search tool above for the quickest match, or check the tyre size on the sidewall (for example, width-profile-rim). Many Cayman 718 setups use different sizes front and rear, so confirm both before ordering.

N-rated (Porsche homologated) tyres are not a UK legal requirement, but they are often recommended to maintain the handling characteristics Porsche intended. If your car is under warranty or you prefer factory-approved fitments, choose N-rated options where available and keep the same tyre specification across each axle.

Mixing brands is not automatically illegal, but it can affect balance and grip on a performance car. As a rule, keep the same tyre size, construction type, and ideally the same brand and pattern on each axle to avoid uneven handling and traction control issues.

The UK legal minimum is 1.6mm across the central three-quarters of the tyre around the full circumference. Many drivers replace performance tyres earlier (often around 3mm) for better wet grip, and you should also replace tyres with sidewall damage, uneven wear, or ageing-related cracking.

After you select tyres, you choose a nearby garage and an appointment slot during checkout. The tyres are delivered to the garage for fitting; pricing for fitting is shown during booking, while optional extras like wheel alignment, TPMS service items, or additional valves may be charged by the fitter if required.
