How to Use This Information

Stay within 3%: All listed tire sizes maintain proper speedometer accuracy and vehicle dynamics
Consider aspect ratio: Lower numbers mean shorter sidewalls (better handling, harsher ride)
Treadwidth matters: Wider tires typically offer more grip but may reduce fuel economy
Check clearance: Ensure your vehicle has adequate wheel well and suspension clearance
