Porsche vehicles use a wide range of OEM tire sizes across their sports car, sedan, and SUV lineup, from performance fitments like 235/45R18 to larger high-performance configurations such as 315/30R22, depending on model and wheel package.
Model examples illustrate this variation: the Porsche 718 Cayman commonly uses 235/45R18, the Porsche 911runs 245/35R20, the Porsche Macan typically uses 235/55R19, while larger SUVs like the Porsche Cayenne often come equipped with 285/40R21.
