What is the correct tire pressure for Lexus NX?

The correct tire pressure for a Lexus NX is the value listed on the vehicle’s Tire Information placard and in the owner's manual. For most NX models, the cold-pressure figures sit in the low-to-mid 30s psi, but the exact numbers depend on model year, wheel size, and whether the vehicle is carrying a heavier load.

Understanding why this matters helps: proper tire pressure optimizes safety, handling, tire wear, and fuel efficiency. Tire pressure can vary with wheel size, trim, and load, so it’s essential to use the specification that corresponds to your specific car. This article explains where to find the official numbers, how to measure them correctly, and how to account for load and temperature when inflating your tires.

Where to find the official specification

The authoritative tire-pressure numbers are printed on the Tire Information placard found on the driver's door jamb and in the owner's manual. The placard lists the recommended cold tire pressures for the front and rear tires, and it may also provide a separate figure for the spare tire. When you replace tires or change wheel sizes, the numbers can change, so always refer to the exact specification for your configuration.

A few key guidelines to keep in mind while using the placard:

• Inflate tires when they are cold, meaning the car hasn’t been driven for several hours or has only been moved short distances.


• Check both front and rear pressures; they are often (but not always) different.


• Don’t rely on the maximum pressure listed on the tire sidewall for inflation—use the vehicle’s recommended figure from the placard or manual.


• If your NX uses a space-saver (temporary) spare, the spare will have its own specified pressure on the spare or in the manual.


• When tires are replaced with different sizes, the placard numbers may change; confirm with the dealer or tire professional.

In most cases, the recommended cold pressures are provided for typical daily driving and moderate loads. If you regularly carry heavy cargo or passengers, or you drive in extreme heat or cold, you may see guidance in the manual about adjusting pressures for load or climate.

With the official numbers in hand, you can set your gauge to those targets and recheck after inflating. If you cannot locate the placard or manual, contact a Lexus dealer or qualified tire shop for the exact figures for your model year and wheel size.

NX variants and tire size considerations

Why tire size matters

Different NX configurations (varying trims and wheel diameters such as 17", 18", or 20" wheels) may have different recommended pressures. The Tire Information placard on your car is the authoritative source that accounts for your specific tire size and load capacity. Always rely on that data rather than generalized numbers.

As a rule of thumb, many NX models with common wheel sizes fall within a mid-30s psi range for both front and rear tires when cold, but the exact values will be printed on your car’s placard. If you’ve upgraded tires or wheels, have the shop confirm the correct pressures for your new configuration.

How to inflate your Lexus NX correctly

Inflating to the correct specification requires careful measurement and proper technique. Below is a practical checklist to ensure accuracy.

• Use a reliable tire gauge (digital or analog) and check the tires when they are cold.


• Refer to the Tire Information placard for the exact cold pressures for the front and rear tires, and, if applicable, the spare.


• Inflate each tire to the recommended pressure, then recheck both tires after a brief rest period to allow the pressure to settle.


• Consider load and driving conditions: heavy cargo, towing, or hot weather can justify adjusting pressures within the ranges specified in the manual or placard.


• Recheck pressure regularly, at least monthly, and before long trips.

Correct inflation is a simple, ongoing maintenance task that pays dividends in safety, handling, and tire longevity. If you’re ever unsure, a quick visit to a Lexus service center or a trusted tire technician can confirm the exact numbers for your particular NX configuration.

Summary

The authoritative tire pressures for a Lexus NX come from the Tire Information placard on the driver’s door jamb and the owner’s manual. While most NX configurations operate in the low-to-mid-30s psi range when cold, the precise front and rear values depend on year, trim, and wheel size. Always use the placard for your car, inflate from cold, and account for load and temperature variations. Regular checks help maintain optimal performance and tire life.

What should Lexus NX tire pressure be?

The correct Lexus NX tire pressure varies by model and tire size, but is generally between 32 and 36 PSI. The most accurate information for your specific vehicle is on the sticker inside the driver's doorjamb or in the owner's manual. For example, the 2021+ NX 350h has a pressure of 33 PSI for 18-inch tires and 36 PSI for 20-inch tires, while some older models may recommend 32 PSI.
 
How to find the correct tire pressure

• Check the sticker: Look for a sticker on the driver's side doorjamb. It provides the recommended PSI for your specific vehicle configuration. 
• Consult the owner's manual: The owner's manual will have a dedicated section for tire pressure information. 
• Check the tire's sidewall: The maximum pressure the tire can hold is listed on its sidewall, but this is not the recommended pressure for your vehicle. 

Examples of recommended tire pressure by model

• 2021+ NX 350h:
  • 235/60 R18 tires: 33 PSI 
  • 235/50 R20 tires: 36 PSI 
• 2019 NX:
  • 225/60 R18 tires: 32 PSI 
• Older models/other sources:
  • 2020 NX300: 32 PSI 
  • Various models: 32-36 PSI is a common range. 

Important tips

• Always check the pressure when the tires are "cold" (driven for less than a mile). 
• Ensure the tire pressure is correct for the vehicle, not just what is listed as the maximum on the tire itself. 

Can I put 87 in my Lexus NX?

If you're looking for a Lexus that runs on 87-octane fuel, there are a few options in the lineup: Lexus ES (ES 250, ES 350, ES 300h) Lexus UX (UX 250h) Lexus NX (NX 250, NX 350, NX 350h)

What is the tire pressure for a 2025 nx350?

The recommended cold tire pressure for a 2025 Lexus NX 350 is 35 PSI (pounds per square inch) for both front and rear tires, as is the case for many 2023-2025 Lexus models. You can find the precise information on a sticker inside the driver's side door frame or in your owner's manual. 
How to check and adjust

• Check when cold: Always check tire pressure when the tires are cold, before you have driven any distance. 
• Use a pressure gauge: Use a reliable tire pressure gauge to check the pressure in each tire. 
• Check the sticker: The recommended pressure is listed on the sticker located inside the driver's side door jamb. 
• Adjust as needed: Add or release air to meet the recommended PSI for all four tires. 
• Use the vehicle's display: The Tire Pressure Monitoring System (TPMS) on the car's display screen can also show you the current pressure for each tire, say these Reddit users. 

Should I use 32 or 35 tire pressure?

For most cars, the recommended tire pressure is between 32 and 35 psi, and you should use the pressure listed on the driver's side door jamb or in the owner's manual. The correct pressure can vary by vehicle, and the pressure on the tire's sidewall is a maximum, not the recommended value. Using the correct pressure ensures proper handling, fuel efficiency, and tire life, while using the wrong pressure can cause poor handling, reduced traction, and premature wear.
 
How to find the right pressure

• Check the sticker on the driver's side door jamb. This is the most reliable source for your specific vehicle. 
• Consult your owner's manual for the manufacturer's recommendation. 
• Note that the pressure should be checked when the tires are cold (before driving). 
• Don't use the pressure listed on the tire's sidewall, as this is the maximum pressure the tire can hold, not the recommended pressure for your car. 

Why the correct pressure is important

• Too low: Can lead to poor fuel economy, premature tire wear, and a higher risk of tire failure. 
• Too high: Can cause reduced traction, an uncomfortable ride, and rapid, uneven tire wear. 
• Correct pressure: Optimizes handling, safety, and fuel efficiency, and helps your tires last longer.
