Maserati GRAN Tires — Fitment by Year

The Maserati Gran Turismo and GranCabrio — spanning the 2008 through 2019 model years — are purpose-built grand touring sports cars designed to balance high-speed performance with long-distance comfort. That combination places specific and non-negotiable demands on tire selection. These vehicles were factory-fitted with staggered tire setups in most configurations, meaning the rear tires are wider than the fronts. That stagger is intentional: it supports rear-biased power delivery and sharp turn-in response, so maintaining the correct stagger when replacing tires is critical to preserving the car's handling balance.

Tire sizes on the Gran Turismo and GranCabrio vary by model year and trim level, so it is essential to confirm the exact front and rear sizes on your specific vehicle before ordering. Common configurations across the range involve low-profile performance tires — often with aspect ratios in the 35 to 45 range — mounted on 19- or 20-inch wheels. These thin sidewalls maximize lateral stiffness and steering precision but offer very little cushion against road irregularities, which is a trade-off characteristic of the grand touring segment. Any replacement tire must carry an adequate speed rating (typically Y or W) to match the car's performance capability.

When choosing a tire category, most Gran Turismo and GranCabrio owners will find that ultra-high-performance summer tires align most closely with the vehicle's original intent. These compounds deliver the grip levels and dry/wet handling characteristics the car was engineered around. All-season tires are a viable alternative for owners in climates with mild winters, but drivers should understand that a broad all-season compound involves real compromises in peak grip and lateral response compared to a dedicated summer tire. Dedicated winter tires — ideally on a separate set of wheels — are the correct choice for regions with sustained snow and freezing temperatures, as the car's performance-oriented summer tires degrade significantly in cold conditions.

The low-profile sidewalls common on these vehicles make ride quality sensitive to tire brand and construction quality. Tires using run-flat construction are an option found on some configurations, but run-flat fitment is typically stiffer and further reduces ride compliance — a meaningful consideration on a car that already transmits road texture clearly into the cabin. Standard tires paired with a portable inflation kit or roadside assistance coverage are a practical alternative if ride quality is a priority. Always verify whether your specific car left the factory with run-flat tires, as mixing run-flat and standard tires on the same axle is not recommended.

Because trim levels, optional wheel packages, and regional specifications all influence the original tire fitment, the most reliable starting point is the placard located in the driver's door jamb or the owner's manual. Cross-reference that information with the actual wheel and tire currently on the car, particularly if the vehicle has had previous wheel or suspension modifications. Verifying your exact year, model variant, and current wheel diameter before selecting a replacement ensures the new tires will seat correctly and perform as intended.
