Yes. Enter your UK registration in the search tool to pull up tyre sizes and options that match your Mazda RX-8, then confirm the details against your tyre sidewall for peace of mind.
Look on the tyre sidewall for a size like 225/45 R18, plus the load and speed rating (for example 91W). You can also check the driver door jamb sticker or the handbook.
Choose the speed rating recommended for your exact RX-8 model and wheel size, shown on the vehicle placard or handbook. Many RX-8 fitments use higher speed ratings, so avoid downgrading unless a tyre professional confirms it is acceptable.
After selecting your tyres, you choose a nearby fitting garage and a time slot. The tyres are delivered to the fitter, and you attend your appointment for installation and balancing.
The UK legal minimum is 1.6 mm across the central three-quarters of the tread around the full circumference. Many drivers replace earlier for better wet grip, especially on a performance car like the Mazda RX-8.
