Lexus Tire Pressure Guide

Proper tire pressure is important for several reasons: under-inflated tires can reduce tire life, reduce fuel economy, and prevent your car from performing at its best. What should the tire pressure be on a Lexus SUV or sedan? Most vehicles require a psi of 32 or 33 for the front and rear tires. For detailed Lexus tire pressure requirements, check your owner’s manual. Have additional questions? This guide from Haldeman Lexus of Princeton covers what else Princeton, NJ drivers should know.

What Should the Tire Pressure Be on a Lexus?

The proper Lexus tire pressure will depend on factors such as the vehicle’s size, type, and model-year. What should tire pressure be on a Lexus SUV? Here, it depends on the size of the vehicle. Most of the lineup’s SUV models require 32 psi for front and rear tires. The smallest Lexus SUV (the sporty subcompact UX) and the largest (the three-row LX) require a higher pressure of 33 psi.

What should tire pressure be on a Lexus sedan? For sedans, it depends on whether the vehicle is engineered for high-speed driving. Here’s how the Lexus tire pressure breaks down for a few of the lineup’s key models:

• Lexus NX Tire Pressure – 32 psi front/rear
• Lexus RX Tire Pressure – 33 to 35 psi front/rear
• Lexus GX Tire Pressure – 32 psi front/rear
• Lexus LX Tire Pressure – 33 psi front/rear

Resetting the Lexus Tire Pressure Warning System

Newer vehicles are equipped with a tire pressure warning system that automatically monitors tire pressure and sends you a warning when the psi of any one tire is too low. As soon as you see this warning on your dashboard, stop into a Hamilton, NJ-area service center or gas station to refill your tires. Once your tires are back to the proper pressure, you will need to reset the Lexus tire pressure sensor. This should be done each time you refill your tires with air or replace a wheel.

Signs That Your Lexus Tire Pressure May Be Too Low

If your vehicle is older and doesn’t have a tire pressure warning system, keep an eye out for these signs that your Lexus tire pressure is getting too low:

• Low responsiveness to the road surface
• Rougher-than-usual ride
• Worsening fuel economy

If you notice these signs, measure your Lexus tire pressure with a tire pressure gauge to be sure. If you’d prefer, you can also bring your vehicle to a Yardley, PA-area service center for an inspection.
