Thats kool thanks for that info, it helps. very very rarely will there be 4 adults in the wife's RX, and I'm in the North East so temp is not a huge factor. got em for a decent price. just tried to look out for the Wife and get her some decent tires, plus my kiddie rides with her too so you know how that goes. me I could care less about what I ride on, that is.. untill I get into an accident..:doh

 

I think that just proves that each person's needs are different. In your case you probably made a wise investment. While you may have gotten a good price, you did not cheap out (Michelin does make a quality tire as opposed to say going with Nankang) and new decent tires are usually much better even high quality well used ones in many regards.

BTW, I grew up in PA and it does get quite hot up there in the NE some summers. Can get hotter there than what I see here in my part of FL. Being close to the water, this area has not seen a 100°F temp ever that I am aware though we get a lot of high 90's. Fortunately for you that it doesn't go on for month after month. Still, the asphalt and concrete roads most everywhere do get extremely hot which is transmitted back to the tires. The tires have their own load stresses which also generate heat. Just a matter of not over stressing the tires and not overloading the vehicle, keeping the tire pressures in the proper range, and perform visual inspections on a regular basis. Do not wait until you need an oil change to have your tires inspected. It is something you can do yourself in a few minutes. When we hear about tire failure accidents on the news there is a high probability that one or more of the above rules was broken.

 

Alchemist, what made you choose these? I've been looking at these and the Cooper CS4 Touring for my 2005 RX330 AWD.
