Thanks for all the input. I had an early 90's Honda Prelude that had a negative camber issue due to sag because of it's age and it would destroy the inside edges of tires within 13,000 miles. It had a load of miles on it, 256,000, and I decided to sell it. I didn't want to put any more money into it. Also wouldn't negative camber create a scenario where the tread height would steadily increase as you measure outward from the inside edge to the outer edge of the tire? What's odd about this wear is as I mentioned I was told everything is in spec and 3/4 of the tread surface is worn evenly except for the last tread channel. I still have the tires and I remeasured the depth and the it's a hair under 4/32 to be exact on that outside channel. I'll keep these new tires at the rated psi on the door and see what's cooking after about 5000 miles. I have a tread gauge. All I know is the CS5s rode like garbage since day one, I never liked them.
