Hi all!
After 16,474 miles with my Insight, I thought I'd update everyone on my tire wear. I've been running my tires at 40psi since new, and I rotate them every 5-6K miles. Today was rotation day (along with hand car wash with my new foam cannon). Attached is a photo my my right-front tire tread. The wear seems even. Although it appears the middle of the tire is closer to the wear indicators, it's an optical illusion due to the camera angle. All four wear indicators show the same depth. After this many miles, I feel confident that running at 40psi does not invoke excess tire wear.
If you don't do it, please rotate your tires. The Insight's TPMS monitor uses wheel rotation speed and harmonics to determine a pressure mismatch. A difference in wear between front/rear/left/right could cause an alert. Also, rotation time is a good time to break out the Mother's Wheel and Tire cleaner to clean up the backside of your wheels along with the visible side. Make sure you have a decent torque wrench when putting the wheels back on. I was stupid with my old Civic and sheared a stud off one time. I set the Harbor Freight click-type torque wrench at 90# now and haven't had an issue.
As for the stock Michelin tires, I would definitely buy them again when the time comes. They've been great in wet and dry conditions - even with the higher pressures. I'm able to avoid snow, so that's not an issue for me.
