| When increasing diameter while aiming to keep same load index, tire width can be reduced. |
| Large tire diameter and high inflation pressure | Narrow tread width |
|---|---|
| Rolling resistance The higher inflation pressure leads to higher belt tension, which might worsen the comfort. | Aerodynamic resistance Pass by noise |
