When I read about the tests I thought the tests were done by independent groups and some testing by State of Ohio. When I worked in field service for a company I drove from Cleveland to a customer
along the Ohio River. There were times I saw a car driving along at 55mph with a sulky behind and one car wheel with a tire and yellow flashing lights. I did not realize it at the time but I think it was State of Ohio doing testing of tread wear for tires they would buy for their vehicles. The read up on temperature was very brief and I did not see more info on it. I would be interested to read more about temp testing if someone would point me in a direction. I thought the info on the Michelin tires helpful. I googled and came up with Top Ten Tires and that was interesting also. I read somewhere the greatest number of tire blowouts was assignable to side wall fails. So I thought getting anA class tire was best hedge against that failure mode.

The other tire that has been discussed on this fourm in comparison to the Michelin CC2 is the Continental Cross Contact LX25. This is NOT a tri-peak rated tire, but for primary highway driving it is rated for 70k miles. So far, this has been the best tire I have ever had on my wife's 2011 Toyota Highlander. We are now approaching 70k miles on these tires and they have been great. If you are NOT in the snow or wet areas a lot of the time, I would recommend the Continental Cross Contact LX25. I will be buying these again for the Highlander and now my R4P.
Thanks for the info, I had my tire guy quote them all and the Continental's were actually the cheapest option available, and looking at some reviews and stuff they seem very comparable grip wise to the CC2's.
Put them on and got the 4 wheel alignment (had positive camber on front and rear 3 and 1.5 degrees respectively despite having an alignment ~13k miles ago... gotta love my dealership...) so far the tires are super quiet and seem grippy enough, though it's been mild here the last couple days so we shall see going forward.

I made reference to this upon earlier discussion. I was speaking to the point of "Temperature Grading". I grabbed the detail level as I was learning. I am sure there are people who know much more than me, but this is my frame of reference for now.
Uniform Tire Quality Grading UTQG is intended to provide simple, comparative data for your use in making an informed buying decision. However, the ratings are based upon test results achieved under very specific conditions. As a result, misinterpreting the comparative data as it relates specifically to your particular driving habits, conditions, etc., is a possibility. UTQG designates the comparative performance levels of a tire based upon government-specified tests. Tire manufacturers and brand name owners are required to grade regular and all-season tires in three categories: Treadwear, Traction, and Temperature.
DOT QUALITY GRADES All passenger car tires must conform to Federal Safety Requirements in addition to these grades.
TREADWEAR The treadwear grade is a comparative grade assigned by the manufacturer based on the wear rate of a tire when tested under controlled conditions on a course that meets government-specified requirements. For example, a tire graded 150 would wear one and a half (1 1/2) times as well as a tire graded 100 under the controlled test conditions. The relative performance of tires depends upon the actual conditions of their use and may depart significantly from the norm due to variations in driving habits, service practices and differences in road characteristics.
TRACTION AA, A, B, C The traction grade is based on wet skid tests of a tire on government-specified concrete and asphalt surfaces. The traction grade is based on a straight-ahead wet braking traction test and does not include a cornering traction test. The comparative tire grade letters, AA, A, B, and C (AA being the highest and C being the lowest) represent the tire's ability to stop the vehicle on wet pavement under the controlled test conditions. Ice and snow traction capabilities are not tested.
WARNING: The traction grade assigned is based on braking (straight ahead) traction test and does not include cornering (turning) traction.
TEMPERATURE A, B, C The temperature grade is based on an indoor, high-speed test that meets government-specified requirements. The comparative grade letters, A, B, and C (A being the highest and C being the lowest) represent the tire's resistance to the generation of heat and its ability to dissipate heat when tested under controlled conditions on a specified indoor laboratory test wheel.
Sustained high temperature can cause the material of the tire to degenerate and reduce tire life, and excessive temperature can lead to sudden tire failure. The grade C corresponds to a level of performance which all passenger car tires must meet under the Federal Motor Vehicle Safety Standard No. 109. Grades A and B represent higher levels of performance on the laboratory test wheel than the minimum required by law.
WARNING:The temperature grade is established for a tire that is properly inflated and not overloaded. Excessive speed, under inflation, or excessive loading, either separately or in combination, can cause heat buildup and possible tire failure.
