I would recommend the Yokohama Avid V4s 235/55/18 tire for the RX330. It is nearly identical in weight to the OE Goodyear tire (29.5 vs. 29 pounds) but the tread width is 1.5 inches wider giving the tire a much more low profile appearance and more rubber on the road. Don't bother with the Bridgestone Dueler Alenza's, they weight 4 pounds more per tire and that much additional unsprung weight will hurt your gas mileage. With high gas prices, the costs add up quickly over time.

DENSO makes the best wiper blades by far. DENSO makes many OE parts for Lexus. I just replaced mine on my '04 RX330 and they are incredibly smooth. You can find the part number you need at densoaftermarket.com. My thoughts exactly. I'm happy with the Ion's so far. What get's replaced when the rear wiper needs to be done?
