Drivers searching for replacement tires for their sedan often begin with the question, what size tires are on nissan altima. This specific inquiry is the logical starting point because selecting the correct diameter and width is fundamental to safety, performance, and fuel efficiency. The Nissan Altima has been a competitive force in the mid-size sedan segment for many years, and understanding its tire specifications is essential for both new owners and those considering a used purchase.
Factory Standard Tire Dimensions
The most common fitment across recent model years of the Nissan Altima is a 215/60R17 tire. This designation indicates a tire that is 215 millimeters wide, with a sidewall height that is 60% of the width, mounted on a 17-inch diameter wheel. This size strikes a balance between a comfortable ride, which is a key attribute of the Altima, and adequate grip for everyday driving conditions. You will find this specification listed on the driver’s door jamb placard and in the owner’s manual as the manufacturer’s recommendation.
Performance and Touring Trim Variations
While the 215/60R17 is the baseline, trim level plays a significant role in the rolling rubber. The Nissan Altima SV trim typically retains the standard 17-inch wheel. However, moving up to the SR and Platinum trims often introduces a move toward a 18-inch wheel, which allows for a larger brake caliper and a more visually aggressive stance. Consequently, the tire size upgrades to 215/50R18, sacrificing a small amount of sidewall cushioning for improved handling dynamics and a sportier appearance.
Seasonal and Alternative Options
Owners in regions with harsh winters might look beyond all-season tires. For the Altima, switching to a dedicated winter tire often involves a size change to 225/50R17 to maintain the overall diameter within an acceptable tolerance. This ensures that the vehicle speedometer remains accurate and that the all-wheel-drive system, if equipped, is not stressed. Conversely, drivers in hot climates may opt for high-performance 225/45R18 tires on 18-inch alloys to reduce heat buildup and enhance dry traction during spirited driving.
Importance of Maintaining the Correct Diameter
When modifying tire sizes, the golden rule is to maintain the overall diameter as close to the factory standard as possible. For the Nissan Altima, this means staying within a 3% deviation. Installing a significantly larger tire can cause the anti-lock braking system and stability control to malfunction, while a significantly smaller tire can result in inaccurate speed readings and increased stress on the drivetrain. Always consult a tire professional if you are considering a size change for confirmation of compatibility.
Practical Considerations for Replacement
Whether you are driving a base model or a well-equipped SL, the search for tires usually comes down to finding the right balance of price, longevity, and comfort. The stock size of 215/60R17 is widely available from numerous reputable brands, ensuring competitive pricing and a vast selection of quality options. When checking tire pressure, remember that the recommended setting is usually around 32 PSI when cold, a detail that is printed on the placard and should be followed regardless of the tire brand you choose.
