The short answer is that you can typically upsize by about one tire size from stock, with most setups landing in the 30–32 inch overall diameter range. Larger tires are possible, but they often require clearance work, suspension tweaks, or wheel/offset changes and can affect speedometer accuracy, braking, and warranty considerations.
This article breaks down tire-size limits by Ridgeline generation, outlines common upsize options, and explains what to check before making a change. It covers Gen 1 (2006–2014) and Gen 2 (2017–present) Ridgelines, along with practical guidance for safe fitting and ongoing maintenance.
Gen 1 Honda Ridgeline (2006–2014): typical options and limits
Gen 1 models used 16- or 17-inch wheels depending on trim, with stock tires generally around the low-to-mid 30s in overall diameter. The exact maximum fitment depends on wheel width, offset, and fender clearance, which vary by trim and factory suspension setup.
- Up to roughly 30.5–31 inches in overall diameter without modifying the suspension or bodywork, using appropriate tire widths on 16" or 17" wheels.
- Common upsizes include 265/70R16 or 265/65R17, which push diameter into the low- to mid-31" range and fit on many trims without major rubbing—though fit can vary by individual vehicle.
- Some owners opt for larger options such as 275/70R16 or 275/65R17, but rubbing on the front bumper, control arms, or fender liners can occur on certain trims; these setups often require trimming or minor bodywork plus careful attention to alignment and camber.
In practice, many Gen 1 Ridgelines are adequately equipped to handle 265/70R16 or 265/65R17 without significant clearance issues. Pushing to larger sizes is possible but risks rubbing and may demand suspension tweaks or body trimming.
Gen 2 Honda Ridgeline (2017–present): typical options and limits
Gen 2 ridgelines come with 18- or 20-inch wheels depending on trim. The stock tire diameter is around the low 30s inches, and upsize options vary by wheel size, offset, and how much clearance you’re willing to alter. Always verify clearance on your exact configuration before purchase.
- With 18-inch wheels: 265/65R18 (about 31.6" diameter) is a common upgrade that fits on many trims; 275/60R18 (about 33") is possible but may rub on some configurations and might require leveling or trimming in some cases.
- With 20-inch wheels: 275/55R20 (about 31.5" diameter) or 265/50R20 (about 30.5") are frequently used options; fitment is generally good on many trims, but clearance and offset should be checked, and some vehicles may benefit from a leveling kit or minor trimming.
As with Gen 1, larger-than-stock tires on Gen 2 can affect speedometer accuracy, braking feel, and suspension dynamics. Depending on the exact trim, wheel offset, and factory ride height, you may need a leveling kit, spacers, or careful fender work to avoid rubbing. Always have a professional verify fitment and recalibrate the speedometer if you change overall diameter significantly.
Summary
Across both generations, the Ridgeline can accommodate larger tires, but the exact size you can safely fit depends on your generation, wheel size, offset, and how much body clearance you’re willing to modify. A conservative approach is to upsize by one tire size from stock (for example, moving from a 18" wheel with a typical ~31" tire to a 265/65R18 or similar). If you want to go beyond that, expect potential rubbing and the need for leveling, trimming, or custom wheel choices, plus attention to speedometer recalibration and warranty implications. Always consult your owner’s manual, a qualified tire shop, and your dealer for confirmation on a configuration that matches your Ridgeline’s exact trim and setup.
