Understanding the correct 2019 Subaru Forester tire size is essential for owners who value the vehicle’s signature capability and comfort. This model, available in variants like the base, Premium, Limited, and Touring, typically comes equipped with 17-inch all-season tires as standard equipment. While 17 inches is the most common size found on new models, specific trims and optional packages may feature 18-inch wheels to enhance the aggressive stance and road presence.
Factory Specifications and Trim Variations
When inspecting a specific 2019 Forester, the wheel size can vary slightly depending on the trim level selected. The base and Premium trims often utilize the 17-inch design, providing a balanced mix of efficiency and durability for daily driving. In contrast, the higher trims such as the Limited and Touring frequently include 18-inch alloy wheels as part of their luxury and performance-oriented packages.
Importance of OEM Specifications
Sticking with the OEM (Original Equipment Manufacturer) recommended 2019 Subaru Forester tire size ensures that the vehicle’s computer systems, including stability control and anti-lock brakes, function as intended. Deviating from the recommended diameter or width can interfere with sensor readings and potentially impact the accuracy of safety features, making it crucial to adhere to Subaru’s guidelines during replacement.
Performance and All-Season Considerations
The 17-inch and 18-inch options on the 2019 Forester are engineered to handle diverse weather conditions, which is a core reason Subaru owners appreciate this model. The sizing supports the symmetrical all-wheel-drive system, allowing for confident traction in rain, light snow, and on dry pavement. Choosing the correct size maintains the vehicle's low rolling resistance, which contributes to the respectable fuel economy the Forester is known for.
Load Index and Speed Rating
Tire size is not the only specification that matters; the load index and speed rating are equally critical for safety. For the 2019 Forester, the typical load index is 91 or 93, indicating the tire's capacity to carry weight, while the speed rating is usually V or H, denoting the maximum safe speed. Always verify these numbers on the tire’s sidewall match or exceed the manufacturer’s recommendations to avoid premature wear or handling issues.
Aftermarket Options and Customization
Owners looking to customize the look of their 2019 Subaru Forester have a wide range of aftermarket tires available. Those opting for 18-inch wheels often select high-performance all-season or touring tires that offer quieter cabins and improved cornering grip. It is vital to ensure that any replacement tire matches the overall diameter within a few percent to prevent drivetrain stress and maintain accurate speedometer readings.
Winter Tire Compatibility
For regions with harsh winters, fitting dedicated winter tires is a popular upgrade. When selecting a 2019 Subaru Forester winter tire, the same diameter and width compatibility rules apply. Many owners successfully use 17-inch winter tires on the stock wheels or opt for 18-inch winter variants if they have upgraded rims, ensuring optimal snow and ice dispersal without sacrificing ride comfort.
Maintenance and Replacement Tips
Regular maintenance is the best way to maximize the lifespan of your 2019 Subaru Forester tires. This includes checking air pressure monthly, rotating the tires every 5,000 to 7,000 miles, and performing visual inspections for cuts or embedded debris. When the tread depth approaches 2/32 of an inch, it is time to replace the tires, regardless of their remaining age, to preserve the vehicle’s safety and performance credentials.
