Either works. Entering your registration is the simplest way to see the correct fitment, while searching by tyre size is useful if you have aftermarket wheels or already know the exact size from the sidewall.
Many AP1 models use 205/55 R16 front and 225/50 R16 rear, while many AP2 models use 215/45 R17 front and 245/40 R17 rear. Always confirm using your tyre sidewall or the vehicle placard, as wheels and sizes can vary.
Not always, but tyres on the same axle should match in size and pattern, and tread depths should be similar. If one axle is significantly more worn or you are changing tyre type, replacing all four can help keep the car’s balance predictable.
Use at least the speed rating and load index specified for your car. The S2000 typically requires high-performance ratings (often W or Y), but you should confirm the exact requirement via your current tyres or the manufacturer information.
After choosing tyres, you select a fitting garage near you and pick an appointment slot. The tyres are delivered to the garage for your visit, and the fitter will install them and dispose of the old tyres in line with UK requirements.
