The size you can fit on a Nissan Altima is largely defined by the trim and generation, but in general you should use the OEM size or a replacement that keeps the overall tire diameter within about 3% of stock. Always start with the door placard or the owner's manual to confirm exact specifications for your vehicle.
Know your OEM size and safe range
To determine the exact options for your Altima’s year and trim, begin with the official specifications listed for your vehicle. The door jamb placard shows the recommended tire size, load rating, and inflation pressure for the original setup. Use this baseline when shopping for replacements.
Use this checklist to determine compatible sizes before you buy tires.
- Find the OEM tire size on the door placard or in the owner's manual.
- Estimate how changes in width, aspect ratio, and wheel diameter affect overall tire diameter, aiming for about a 3% difference from stock.
- Ensure the chosen size will clear fenders, suspension, and brakes without rubbing, especially when turning or under full load.
- Match or exceed the OEM load index and speed rating to preserve safety and performance.
- Be aware that changing tire diameter can affect the speedometer accuracy, ABS, and traction control; consult a tire professional if in doubt.
By following these steps, you can choose a tire size that is safe, compliant with your Altima’s systems, and appropriate for daily driving or performance needs.
Typical tire size ranges by wheel diameter
These ranges reflect common configurations seen on modern Nissan Altima trims. Exact sizes vary by model year and trim, so always verify with your specific vehicle’s specifications before purchasing.
- 16-inch wheels: commonly around 205/60R16 or 205/65R16
- 17-inch wheels: commonly around 215/55R17 or 225/50R17
- 18-inch wheels: commonly around 235/45R18
- 19-inch wheels: commonly around 235/40R19 or 245/40R19
Sizes above are intended as general guidance. The exact OEM specification for your Altima may differ by year and trim, so always confirm with the door placard or dealer documentation before purchasing tires.
Special considerations for upsize, downsize, and performance setups
Upsizing to larger wheels
Moving to larger wheels typically requires selecting tires with lower profile to maintain a similar overall diameter. If you go up a wheel size, aim to keep the total diameter within about 3% of stock. Be mindful of potential impacts on ride comfort, acceleration, braking feel, and clearance. Some larger-wheel setups may affect ride quality and instrument calibration, so professional fitting is advised.
Winter and seasonal tires
Many Altima owners swap to dedicated winter tires on smaller or mid-sized wheels. When using winter tires, verify the size recommendations for cold-weather performance and maintain appropriate load ratings. If you use winter tires on larger wheels, ensure clearance and that the tires still meet speed/load requirements.
What to avoid and practical tips
Avoid mixing front and rear tire sizes on all-wheel-drive configurations unless specifically approved, and never select sizes that rub or interfere with suspension components. Do not exceed the vehicle’s stated load rating, and ensure the selected tires maintain accuracy of the speedometer and vehicle safety systems.
Summary
To choose tires for a Nissan Altima, start with the OEM size shown on the door placard and keep the overall diameter within roughly 3% of stock. Use sizes that preserve proper load and speed ratings, and ensure there is adequate clearance around the wheels. Exact sizes vary by generation and trim, so always verify model-year specifics before purchasing. If in doubt, consult a tire professional or your Nissan dealer to confirm compatibility with your vehicle’s systems and warranty considerations.
