Ok, I've had mine on for a few days and driven over a hundred miles on them. No tank refills yet. Changed from worn out no-name 175/70/13's on steelies to brand new 185/55/15 Avid Ascends on steelies.

First impressions are that they do seem to roll better and I can coast for a long time. It has been mentioned that they have good handling as well. They have decent road holding, but are not terribly responsive. Obviously they're not racing tires or anything, but I really beat the **** out of them in an open lot tonight and they seem competent. If you push them hard they lose traction gradually and are reasonably predictable. Come to think about it, they handle a lot like my skinnier no-name tires.

So, while you're not going to have a lot of fun driving these through the twisties, they also aren't going to let you careen into a ditch. Remember, just preliminary seat-of-the-pants review. Watch my fuel log in the future for any MPG changes.

Bottom line: Yes, would recommend for a hypermiler. But if you like to go racing on the weekends, buy a set of sport tires. I plan to buy some Falken Azenis RT-615's for the weekends.

PS- the 185/55/15's do have some sidewall bulge on 7" wheels. I would recommend 7.5" or even 8" wheels if you're concerned about aesthetics and fitment. The latter will probably stretch a tiny bit.
