There isn’t a single tire size for every Ridgeline; it depends on the model year and trim. The most common OEM sizes are 245/65R17 for 17-inch wheels and 265/60R18 for 18-inch wheels, but you should confirm with the door placard or owner’s manual.
Understanding the tire size by generation
Honda has offered Ridgeline models with different wheel sizes across its two generations (2006–2014 and 2017–present). The exact tire size is tied to the wheel diameter and the specific trim, so always verify from the vehicle’s placard or the manual when purchasing tires or performing an upgrade.
First generation Ridgeline (2006–2014)
The following size is typical for first-generation Ridgelines with 17-inch wheels.
- 245/65R17 — Common OEM size for many 17-inch configurations (verify on the door placard).
For 18-inch wheel configurations in the first generation, sizes can vary by trim and option packages; always check the door placard for the exact specification.
Second generation Ridgeline (2017–present)
The second generation introduced larger wheel options. Many trims rely on 18-inch wheels; typical OEM size is 265/60R18, while some lower trims used 17-inch wheels with 245/65R17. Always refer to the placard for exact size.
- 245/65R17 — For Ridgelines equipped with 17-inch wheels (common on base trims).
- 265/60R18 — Common on Ridgelines with 18-inch wheels (RTL, RTL-T, Black Edition, etc.).
Concluding for the second-generation list: For 2017–present Ridgelines, 17-inch wheels often use 245/65R17 and 18-inch wheels often use 265/60R18; confirm with the vehicle’s placard.
Important notes for tire replacement
When replacing tires, aim to match the original overall diameter to maintain speedometer accuracy, ABS/traction control functions, and drivetrain behavior. If you upgrade wheel size or choose a different aspect ratio, consider consulting a tire professional to ensure proper fitment and clearance, and verify load index and speed rating suitable for the Ridgeline’s payload and use.
Summary
In short, the Ridgeline does not have one universal tire size. The correct size depends on year, trim, and wheel diameter. Typical OEM sizes include 245/65R17 for 17-inch wheels and 265/60R18 for 18-inch wheels, but always verify with the door jamb placard or the owner’s manual before purchasing or replacing tires. If upgrading, keep diameter within a narrow tolerance and ensure compatibility with drivetrain systems.
