What is the recommended tire pressure for a 2018 Honda Odyssey?

The 2018 Honda Odyssey uses 36 PSI cold on the front axle and 36 PSI cold on the rear axle. These are the OEM specifications. Always measure tire pressure when the tires are cold — before driving or after sitting for at least 3 hours.

What tire size does the 2018 Honda Odyssey use?

The standard (base trim) tire size for the 2018 Honda Odyssey is 235/60R18. Higher trim levels and optional packages may use a different size — check the sticker inside your driver's door for the exact specification for your vehicle.

How do I convert the 2018 Honda Odyssey tire pressure to bar?

36 PSI = 2.5 bar (front) and 36 PSI = 2.5 bar (rear). In kPa: 248 kPa front and 248 kPa rear. Multiply PSI × 0.0689 to convert to bar.

Why are the front and rear tire pressures the same on the 2018 Honda Odyssey?

The 2018 Honda Odyssey uses equal pressure front and rear (36 PSI). The vehicle's weight distribution and symmetric tire sizing mean both axles carry similar loads per tire.

What happens if the 2018 Honda Odyssey tires are underinflated?

Running 5+ PSI low on the Honda Odyssey causes uneven shoulder wear, increased rolling resistance (worse fuel economy), higher tire operating temperature, and reduced wet braking performance. In extreme cases, chronic underinflation can cause sidewall failure. Check pressure monthly and always after a large temperature swing.

What do the numbers in 235/60R18 mean on the 2018 Honda Odyssey?

On the 2018 Honda Odyssey, 235/60R18 breaks down as: 235 = section width in millimetres (9.25"), 60 = aspect ratio (the sidewall is 60% of the width, so 141 mm / 5.55" tall), R = radial construction, and 18 = the wheel diameter in inches.

What is the overall diameter of the 2018 Honda Odyssey tires?

The 235/60R18 tire on the 2018 Honda Odyssey has an overall diameter of about 29.1" (739 mm) and a rolling circumference of roughly 91.43", giving about 693 revolutions per mile. Fitting a tire with a different diameter will throw off your speedometer and odometer.
