2020 Nissan Pathfinder
2020 Pathfinder cold pressures from the owner's manual checking table, including the spare. Measure the tires cold.
| Item | Figure |
|---|---|
| 235/65R18, front and rear | 33 psi, 230 kPa |
| 235/55R20, front and rear | 35 psi, 240 kPa |
| 255/60R18, front and rear | 36 psi, 250 kPa |
| Temporary spare T165/90D18 | 60 psi, 420 kPa |
| 235/55R20 at 100 mph or higher | 38 psi, 260 kPa, where that speed is legal. Return to the cold pressure afterward. |
| When the tire is cold | Parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds. |

Difficulty, time, and cost are estimates when this guide gives them. Torque is a cited figure, or it is left off.

Tire pressure gauge
Press the gauge squarely on the valve stem. If you hear air escaping, reseat it.

| 235/65R18, front and rear | 33 psi, 230 kPa | Checking tire pressure |
| 235/55R20, front and rear | 35 psi, 240 kPa | Checking tire pressure |
| 255/60R18, front and rear | 36 psi, 250 kPa | Checking tire pressure |
| Temporary spare T165/90D18 | 60 psi, 420 kPa | Checking tire pressure |
| 235/55R20 at 100 mph or higher | 38 psi, 260 kPa, where that speed is legal. Return to the cold pressure afterward. | March 2020 tire-pressure supplement |
| When the tire is cold | Parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds. | Tire inflation pressure |
A tire is cold after the vehicle has been parked for 3 or more hours, or driven less than 1 mile (1.6 km) at moderate speeds.
Remove the valve cap, press the gauge on squarely, and compare the reading with the size in this year's table. Add or release air, recheck, and install the cap. Check every tire, including the spare.
The March 2020 supplement revises the tire-pressure section. It keeps these cold pressures and adds a high-speed row. If the vehicle is driven at 100 mph (160 km/h) or higher where that is legal, the supplement prints 38 psi, 260 kPa for the 235/55R20 original tire. It does not print a high-speed figure for the other sizes in that chart. After high-speed operation, return the tires to the cold pressure.
2020 Pathfinder Owner's Manual. Publication SU20EA 0R52U0, March 2020, is the tire-pressure supplement bound at the front of the same PDF. The March 2020 supplement revises the tire-pressure section. It keeps these cold pressures and adds a high-speed row.
The wheel lug nut guide is the torque after a wheel is installed. It is not a tire pressure.

Yes. The book says the recommended pressures are on the certification label or the Tire and Loading Information label. The checking table prints the figures for the original sizes it lists.
The maintenance checklist is on the site now. The email list is not sending yet, so this box will not store an address.
Same repair, different model year. Use the page that matches the truck or car in the driveway. A figure on one year is not a figure for the next.
These guides cover the same kind of work. Their numbers belong to those vehicles, not to this one.
