good summer tires

Michelin doesn't make that Pilot Sport PS2 in the size or load range of your RX. Neither does Pirelli.
So are you planning on living with speedo error?
Also there is the little matter of load range. The tires you are looking at have an inadequate minimal load carrying capacity for your RX. The OEM tires have a load carrying capacity of 1709 pounds while the Michelin Pilot PS2 has a load capacity of only 1521 pounds. This tire would be dangerous on the RX. On your RX that is over 750 pounds of reduction in load carrying capacity. Your RX Gross Weight: 5650 lbs. With just two occupants weighing 220 pounds each you would have exceeded the tires maximum weight handling capacity. 1521 x 4 = 6084 pounds. Gross weight of 5650 pounds plus the 440 pounds of two passengers = 6090 pounds. See where this is going?
Get some professional advice before you do this or you may hurt yourself, your family or others.

A friend of mine bought a set of UHP tires for his Porsche 911 and even with easy street driving they wore out in 3,000 miles. He only did that once. When I bought my Boxster S it had some UHP tires on it and I could actually see the wear on the tires increase every time I drove it.
JKT: Even though I store my Boxster in the winter, and for the most part don't even drive it in the rain, I run all-season tires with a much higher treadwear rating. I run Bridgestone Potenza RE960AS on that car. They are very sporty and to me they seem to grip very well. So far I'm happy with them and would buy them again. I don't know if they come in a size that will work for the RX, but like I said earlier, the RX isn't exactly a high performance sports car anyway.

If you have your mind made up on summer tires here is another option or two to think about.
Have you consider Plus sizing? This is where you would replace your 235/55-18 tires with 255/50-18. You would need to check fitment and offset but this would open up a larger number of performance category tires to you. The circumference of these tires will remain roughly the same so there would be little speedo or odo error. Pay attention to the load rating and don't go below 99.
Another option would be to replace your wheels along with tires. This allows you to put 19" up to 23" wheels and very low profile tires on the RX. 255/40-20 looks particularly good on the RX. Again, you would need to have a pro examine fitment and offsets before moving down this path. You might well need/want to modify your spring & strut package to deal with this properly but others have done this. This route does get expensive.
One last comment on summer tires. As a group, they are a noisy bunch of skins and esthetically are not quite a good match for a Luxury vehicle.
Have you looked at the tirerack.com website?
Here is a tire fitment site that should help.

If I were to buy new tires for my RX tomorrow I'd buy either the Bridgestone Alenzas or the Yokohama Parada Spec-X.

Thanks for all the great info! Looking at the General Exclaim. uhp ..seems to have very good reviews and a modest price to boot! Any experience with this tire is welcomed.

Just put on Yokahama YK520's on mine today. Discount Tire sells them. Definitely a quieter and smoother ride that my GY Eagles. Haven't got to put many miles on them yet though.
