Factors to Consider When Choosing Tires for Different Trims

Driving Conditions
- For Base, S, and SL trims, all-season tires like 215/60R16 or 215/55R17 provide a smooth ride and fuel efficiency.
- For 3.5 SR trims, performance tires like 235/45R18 deliver improved cornering, braking, and grip.
- In snowy regions, winter tires for all trim levels ensure safer driving.
Comfort vs. Performance
- Higher-profile tires on smaller rims (e.g., 215/60R16) absorb road imperfections, enhancing comfort.
- Lower-profile tires (e.g., 235/45R18) on 18-inch wheels provide sharper handling but can sacrifice ride comfort.
Aesthetics
Sportier trims like the 3.5 SR Coupe benefit from 18-inch wheels and lower-profile tires for a sleek, aggressive look. Smaller trims maintain a more conservative design with 16- or 17-inch wheels.
