The most common stock tire sizes for the 2006 Ridgeline are P245/65R17 on 17-inch wheels (for RTL/RTL‑A trims) and P245/70R16 on 16-inch wheels (for RT/RTS trims). Always verify the exact size shown on your vehicle’s door placard or in the owner's manual.
In 2006, the Ridgeline was offered with different wheel options depending on trim level, which means the factory tire size can vary. This article outlines the typical sizes you’re likely to encounter and how to confirm the correct specification for your particular truck.
Common stock tire sizes by wheel size
The Ridgeline’s tire size depends on whether the vehicle came with 16-inch or 17-inch wheels. Here are the typical factory sizes you’d see from that era:
- RT/RTS trims with 16-inch wheels: P245/70R16
- RTL/RTL-A trims with 17-inch wheels: P245/65R17
Note: Some early-production or region-specific units may have slight variations. Always check the door jamb sticker and your owner’s manual for the exact specification. The spare tire size can differ from the road tires and may be a compact donut or a full-size spare that matches the wheel size of your vehicle.
Trim-specific notes
Because wheel size changed across trims, the tire width and aspect ratio align with a balance between ride comfort, load capacity, and ground clearance. If you’re replacing tires, ensure the new tires match the recommended size, load index, and speed rating for your trim and driving conditions. If you’re unsure of your trim’s wheel size, consult the placard on the driver’s door or a trusted mechanic.
How to verify your exact size on your Ridgeline
To confirm the correct tire size for your specific vehicle, follow these steps:
- Check the driver’s door jamb placard for the recommended tire size and inflation pressures.
- Look at the sidewall of the current tires for the size stamped on them (for example, P245/70R16).
- Consult the owner’s manual or contact a Honda dealer with your VIN for exact specifications.
- If you’re changing wheel sizes (e.g., toward a different trim’s wheel), verify that the overall diameter remains within acceptable limits to avoid speedometer error or clearance issues.
Verifying the correct size helps ensure proper handling, load capacity, and ride quality. When in doubt, a professional tire shop can confirm compatibility with your Ridgeline’s suspension and drivetrain.
Important considerations when replacing tires
Beyond size, consider load rating, speed rating, tread pattern, and climate needs. All-season radials are common for everyday use, while winter tires are recommended for cold climates. If you plan to change wheel diameter (for example, from 16" to 17"), ensure the chosen tires maintain an overall diameter within a small percentage of the original to keep the speedometer accurate and avoid ABS/traction control issues.
Summary: For a 2006 Honda Ridgeline, the stock tire size typically comes in two configurations based on wheel size—P245/70R16 for 16-inch wheels (RT/RTS trims) and P245/65R17 for 17-inch wheels (RTL/RTL-A trims). Always verify with the door placard or the owner’s manual, and consider the load and speed ratings when replacing tires.
