So the recommended psi for the RX330 with 18" alloys is 30 psi. Although, this makes for good cushy ride, I decided to experiment with the tire pressure. I increased the pressure to 35 psi all around and the vehicle feels better, in terms of feel and control. Still not a sports car, mind you, but feels slightly more planted and I can tell what the front wheel are doing. Consequently, slightly more feedback and bumps from rough roads, but nothing objectionable. It might be worthwhile for others to experiment with the tire pressure. I probably will leave them at this pressure.

I do this on my RX300, though I have 235-70-16 tires over the 225 bases tires. This allows for a 44 max. I run them up to 38 as 30 was costing me time on the track and giving me bad MPG. Plus, the tires they sell here south of the border are even tougher than the same model sold in the U.S.

One other goody to do, change your tires over to nitrogen-inflated ones. Costco can do this though I have my own supplier hear. Much, much better ride.

I had 35psi on all 4 tires but the ride was kinda of bumpy. So, I lower it to 30psi as recommended by the manual. Guess what .....my gas mileage improved!

I have been running 36psi for the last 3 years, and on Nitrogen for the last 6 months. Highly recommended.

Where do you find out where to get Nitrogen?

Nitrogen has been added to all the Costcos. So for all those who purchased their Cross Terrains on sale at Costco, your free rotation and balance now includes an upgrade to nitrogen.
