Drivers searching for precise specifications for the 2019 Hyundai Santa Fe often focus on tire size as a critical factor for safety, performance, and replacement costs. Understanding the specific dimensions and load ratings for your specific trim level is essential for ensuring optimal handling, fuel efficiency, and tread wear. This guide breaks down the standard configurations and options available for the 2019 model year.
Standard Tire Dimensions by Trim Level
The 2019 Hyundai Santa Fe offered a range of trims, and while the base tire size was largely consistent, the higher trims featuring larger alloy wheels required different specifications to maintain the intended ride quality and speedometer accuracy.
SE, SEL, and Limited trims
For the base SE, SEL, and mid-level Limited trims, the standard fitment was 17-inch alloy wheels wearing P225/65R17 all-season tires. This combination provided a balanced mix of comfort and durability suitable for daily commuting and family transportation needs.
Sport and Ultimate trims
Customers who opted for the Sport and top-tier Ultimate trims benefited from a more aggressive stance, equipped with 19-inch aluminum wheels. These larger rims were shod with P225/55R19 low-profile tires, which offered improved handling dynamics and a sportier aesthetic at the cost of a slightly firmer ride over rough surfaces.
Understanding the Tire Code
Deciphering the markings on the sidewall of your tire is the best way to confirm you have the correct replacement part. The code is not random; it specifically indicates the width, aspect ratio, and construction type required for your Santa Fe.
Metric Breakdown
The code "P225/65R17" serves as a perfect example for the base models. The "P" denotes that it is a passenger car tire. The "225" represents the width of the tire in millimeters from sidewall to sidewall. The "65" is the aspect ratio, which is the height of the tire's sidewall expressed as a percentage of the width. Finally, the "R17" indicates a Radial construction designed to fit a 17-inch diameter wheel.
Load Index and Speed Rating
Safety extends beyond just the physical dimensions of the rubber. Every tire has a load index and speed rating that dictate its capabilities beyond the tread pattern.
For the majority of 2019 Santa Fe models, the tires typically feature a load index of 100, which means they can safely support 1,760 pounds per tire. The speed rating is usually "S," which corresponds to a maximum speed capability of 112 mph. While exceeding this speed is dangerous, these ratings ensure the tire can handle the stresses of highway driving and emergency maneuvers.
Tire Pressure and Maintenance
Maintaining the correct air pressure is perhaps the most important factor in tire longevity and safety for the Santa Fe. Hyundai specifies the ideal pressure not in the sidewall of the tire, but on a sticker located on the driver’s side door jamb.
For the 2019 models, the standard recommended cold tire pressure is usually around 32 PSI for the front and rear tires. However, this can vary slightly depending on the specific trim and the weight distribution of the vehicle. Under-inflation leads to uneven wear on the outer edges of the tread and reduces fuel economy, while over-inflation makes the ride harsher and creates a center tread wear pattern.
Aftermarket Considerations and Upgrades
Many owners choose to modify the look of their Santa Fe by installing larger wheels or performance tires. If you are considering an upgrade, it is vital to maintain the overall tire diameter within 3% of the factory specification.
