Getting the right 2017 Nissan Altima tire size keeps your sedan riding smoothly, braking safely, and hitting expected fuel economy numbers. Factory specifications vary by trim level, ranging from standard 16-inch wheels on base models to larger 18-inch options on sportier editions. Knowing your exact factory spec prevents clearance issues, speedometer calibration errors, and premature tread wear.
Most 2017 Nissan Altima models roll out of the factory with one of three primary tire sizes depending on whether you drive the 2.5 S, 2.5 SR, 2.5 SV, 2.5 SL, or the V6-powered 3.5 SL. Base trims like the 2.5 use 215/60R16 tires mounted on 16-inch steel or alloy wheels. Mid-tier trims including the 2.5 S, SV, and SL step up to 215/55R17 or 215/60R17 setups, while the sporty 2.5 SR and the powerhouse 3.5 SL utilize wider 235/45R18 tires on larger 18-inch alloy rims.
Factory Tire Size by Trim Level
Matching replacement rubber to your exact sub-model matters because Nissan engineered suspension components and suspension tuning around specific wheel and tire weights. Check the placard located on the driver-side door jamb to confirm your specific vehicle's factory requirements before buying new sets.
- 2.5 and 2.5 Base: Equipped with 215/60R16 tires on 16x7-inch wheels, prioritizing ride comfort and rolling efficiency.
- 2.5 S, 2.5 SV, and 2.5 SL: Typically feature 215/55R17 or 215/60R17 tires on 17-inch alloy wheels, offering a balanced blend of comfort and responsive handling.
- 2.5 SR and 3.5 SR: Sport-tuned trims riding on 235/45R18 tires paired with 18-inch aluminum-alloy wheels for sharper cornering grip and a lower profile sidewall.
- 3.5 SL: The top-tier V6 model utilizes 215/55R17 or upgrades to the 235/45R18 depending on package options chosen at purchase.

Reading Your Sidewall Specs
Understanding what the numbers and letters on your tire sidewall mean helps you avoid costly ordering mistakes. Every tire features a standard Department of Transportation sizing code.
For instance, on a standard Altima tire reading P215/55R17 94V:
- P: Stands for Passenger vehicle service, indicating the tire is engineered primarily for cars and minivans.
- 215: Represents the nominal section width of the tire measured in millimeters from sidewall to sidewall.
- 55: Denotes the aspect ratio. The height of the tire's sidewall is 55 percent of its total width.
- R: Stands for Radial construction, which is the industry standard for modern passenger vehicle tires.
- 17: Indicates the diameter of the wheel rim in inches that the tire is designed to fit.
- 94V: The service description combining the load index (94, meaning a maximum load capacity of 1,477 pounds per tire) and the speed rating (V, safe for sustained speeds up to 149 mph).
Upgrading and Plus-Sizing Options
Many owners look to alter their wheel setup for a more aggressive stance or better handling. While plus-sizing is possible, you must maintain overall rolling diameter within a two percent tolerance of the factory specification to prevent rubbing against fender liners or throwing off your anti-lock braking system sensors.
Switching from 16-inch wheels to 17 or 18-inch aftermarket rims requires matching tires with correspondingly lower aspect ratios. For example, moving from a 215/60R16 up to an 18-inch wheel usually means running a 235/45R18 tire. This maintains the total outer circumference while widening the contact patch for improved dry grip. Keep in mind that wider tires increase rolling resistance slightly, which can shave a fraction of a mile per gallon off your highway fuel efficiency.
You can cross-reference tire dimensions and industry standards using guidelines provided by the National Highway Traffic Safety Administration regarding tire safety and load limits.
Common Tire Maintenance Mistakes
Installing the correct size is only half the battle. Neglecting routine maintenance leads to uneven wear and shortened tread life on your Altima.
- Ignoring Inflation Pressures: Running tires underinflated builds excessive internal heat and destroys sidewalls. Keep your Altima tires set to the factory cold pressure recommendation of 33 PSI, typically listed on the door sticker.
- Skipping Tire Rotations: Front-wheel-drive sedans wear front tires out nearly twice as fast as rear tires. Rotate your tires every 5,000 to 7,500 miles to promote even wear patterns.
- Forgetting Wheel Alignments: Potholes and curb strikes knock front-end geometry out of alignment, causing rapid feathering on the inside edges of your tread. Check alignment whenever you install a fresh set of rubber.
Frequently Asked Questions
Can I put 18-inch tires on a 2017 Nissan Altima that came with 16-inch wheels?
Yes, but you have to replace the wheels as well. You cannot mount an 18-inch tire onto a 16-inch rim. Ensure you choose a low-profile size like 235/45R18 so the overall outer diameter matches your original factory setup.
What is the recommended tire pressure for a 2017 Nissan Altima?
The factory cold tire pressure for most trims is 33 PSI for both front and rear tires. Always check the specific placard on your driver-side door jamb because cargo weight and exact trim specifications can alter this figure slightly.
Will changing my tire size void my car warranty?
Changing tire sizes alone does not void your vehicle's overall warranty. However, if an aftermarket wheel or tire combination causes premature failure of a suspension or steering component, the manufacturer can deny warranty coverage for that specific repair.
How often should I replace the tires on my Altima?
Most standard all-season tires last between 45,000 and 60,000 miles, depending on driving habits, road conditions, and maintenance regularity. Replace your tires immediately if tread depth drops below 2/32 of an inch or if you spot sidewall cracking.
