TireGeoCalc2026 Honda Ridgeline Tire Size by Trim
The 2026 Honda Ridgeline comes with one factory tire size in Honda's specifications: 245/60R18. The size depends on the trim and the wheel. The table below lists each size with the trims it is printed for in the source, plus the overall diameter and revolutions per mile calculated from the size code.
| Trim | Factory tire size | Diameter | Revs per mile |
|---|---|---|---|
| Sport, RTL, Black Edition | 245/60R18 | 29.6 in | 682 |
Note: The source marks TrailSport with all-terrain tires but does not print their size, so TrailSport is not listed here.
How to find the size on your own Ridgeline
Trims, packages and model years can change the factory size. The size that applies to your vehicle is printed on the tire placard on the driver's door jamb and in the owner's manual. The size on the tires now fitted is molded into the sidewall, for example 245/60R18. If the placard and the tires do not match, a previous owner or a shop may have changed the size.
A "P" in front of the size means a P-metric passenger tire. "LT" means a light truck tire, which uses different load and inflation tables. Check the load index and speed rating on the placard before you buy replacements. How to read a tire sidewall explains each part of the code.
