You can find Porsche 911 tyre options at Tyres.co.uk, including the Michelin Pilot Sport 4 S and the Pirelli P Zero in a 295/35 ZR20 at the back and 235/40 ZR19 at the front for the Carrera 992.2. Keep in mind the load and speed index, XL size, speed ratings, and staggered fitment. Carrera S, GTS, Turbo, and GT models may have differing specifications.
The tyre size of the Porsche 911 can be found on the Tyre-pressure placard located in the left-hand driver's door aperture and, as the door is opened, is accessible. This placard will show different approvals for front and rear wheels with their respective sizes and pressures along with the required load. Generations and trims of the 911 are of varying designs and therefore, staggered, so check against the handbook and the registration.
Porsche 911 models do not require four new tyres simultaneously, however, the same make, type, and specification-code and tread depth must be used per axle. The Carrera 4, Targa 4, and other models with all-wheel drive must also ensure that the front and rear wheels are the same rolling diameter. When one axle is replaced, according to recommended UK tyre safety guidelines, the new pair must be placed at the rear axle.
