Mechanic Tip
Cold Inflation Calibration Rule: Tire pressure drops roughly 1 PSI for every 10 degrees Fahrenheit drop in ambient temperature. Furthermore, driving even 1 mile generates internal friction that raises tire pressure by 3 to 5 PSI above true ambient resting level. Never set your tire pressure to the "Max PSI" molded on the tire sidewall, which indicates the maximum mechanical burst rating of the casing. Always calibrate tire pressure when the vehicle has rested for at least 3 hours, matching the cold PSI specified on the yellow-and-white driver-side door jamb placard.

Honda Pilot tire size on the current third-gen (2023+) is three stamps in the owner's manual: 255/60R18, 265/60R18 and 255/50R20. TrailSport takes the wider 18. Touring and Elite take the 20. The LX and Sport usually take the 255/60R18. Year and package still beat a guess.

Stock sizes by trim

Honda prints all three sizes in the 2025 Pilot manual as available regular tires. That is honest: the same nameplate ships more than one. The 265/60R18 also shows up as the full-size spare on some trims, which is a clue it clears the well.

Why the sticker beats the chart

A Pilot that tows or sits on 20s already has a different load and a different ride than the 18-inch truck. Match the load index on the placard, not just the geometry. The load index page is that table.

This is not a fitment database

A Honda Pilot can leave the factory on more than one size. Export markets, mid-year packages and previous-owner plus-sizes all disagree with a chart. Read the driver-door placard. Match width, aspect ratio and rim together.

Swapping to a different size

255/60R18 is about 30.0 inches. 265/60R18 is about 30.5. 255/50R20 is about 30.0. The 20-inch package is plus-two with diameter held. The TrailSport is a wider, slightly taller 18. If you want more than that, you are in Tacoma/F-150 territory and the tire size chart is the next table.

Pilot vs Passport

Passport shares the 18- and 20-inch idea and some of the stamps (245/60R18 and 255/50R20 on older and Elite rows). They are not the same vehicle. Do not order a Pilot TrailSport 265 for a Passport because the numbers look close. Read that door.
