Choosing Tires for Subcompact Cars
When replacing tires on a subcompact car, start by locating the tire placard on the driver's side door jamb, which lists the vehicle manufacturer's recommended tire size, load index, and speed rating. Your replacement tires must match these specifications exactly. Typical subcompact vehicles use sizes around 195/65R15, though some models may have 16 or 17-inch wheels. Never substitute a different size without consulting the placard, as improper sizing affects speedometer accuracy, fuel economy, and safety performance.
Next, consider which tire season type suits your climate and driving patterns. All-season tires work well in mild to moderate climates with varied weather, offering balanced performance year-round. Summer tires deliver superior handling and braking in warm conditions but lack grip in cold or icy weather. Winter tires are essential if you regularly drive in snow or temperatures below 45 degrees Fahrenheit, providing traction that all-season and summer tires cannot match in freezing conditions.
Finally, confirm fitment by checking the door-jamb placard one more time before purchase. This specification sheet is your definitive guide and supersedes any other guidance. Purchasing tires that match these recommendations ensures your vehicle operates safely and maintains the performance characteristics its manufacturer designed.

Match the size, load and speed rating
Start from the original-equipment size for the segment and keep the same load index and speed rating, or higher — these protect the vehicle's carrying capacity and handling. Then match the season type to how you drive. Whatever you choose, the size on your door-jamb tire placard is what to confirm against, because trims within a class differ.
