In a nutshell, I love the 165/65/14 RE 92's. They are the lowest RR tire you can get and are worth 1-3 MPG. If you read the reviews on tirerack, you would think that they are deathtrap tires, stories of disaster abound. But I have had excellent results with mine at 60PSI. Treadwear is normal and dry traction is exceptional. Wet traction is adequate for my needs. I havent driven them in the snow but I don't think that they will do too well. Bottom line, if you drive like a hypermiler, then the tires perform well. If you are likw the other 99% of drivers who go from full throttle to full ABS brakes, then they are not for you. So far I have 12k miles, expecting 40-50k based on current wear.
I have 10k miles on my RE92's and they look, ride and feel like they did on mile 1. Of course the speed limit and almost no braking and no acceleration will do that for ya. I have 44psi in them and check/add once a week. I know I could go higher, just haven't yet.
