  2. Fuel Economy – Smaller 16-inch and 17-inch tires minimize wheel rotational mass, reducing fuel consumption. LX and EX trims don’t need larger tires.
  3. Ride Comfort – Larger sidewall cushions impacts and absorbs road irregularities. This complements luxury focused Touring models.
  4. Responsiveness – Lower profile tires like on the Type R provide sharper turn-in and cornering response. High performance demands more responsive tires.
  5. Cost – Smaller, narrower tires are less expensive for lower trims to keep pricing down.
