Stick with Michelin.... as Lexus wants. Drive fast on what they want is a hard tire is a good idea. Gooey Goodyears will wear out. Drive sane and go with high pressure Michelin and the traction.... Michelin can take it. Listen to what the manufacturer says. *BLEEP* Goodyear. They are too soft and wear out saking reality. This is why you need a real tire that can take 44 psi.

Absolutely... see what the 2009 Consumer Reports issue has to say on the subject on the RX350. The 2009 New Car issue states that sand and snow traction are one of the strongest features of the RX350. Deflation of the tires may help but you can always deflate after you are there if there is a traction problem. Taking a tire gauge (and maybe a portable compressor) would be a good idea to make sure you have equal pressure for fun for sand surfing and then heading back to your original destination. If not... I figure you have Road Service, lol.... go for it. I know you won't be disappointed.

Tires are good for 44 psi... and saves fuel... try that. Why not make your 350RX get excellent mileage?
