See, now that would seem bass ackwards to me. Usually a sticky, performance tire that would be true of, in which case they would be rated at maybe 40K mile tread wear warranty. The comfortreads are what, 80K miles? I'd think they'd be a harder compound like a touring tire, that will last a lot longer than a performance tire.
With that said, her Ion that has them OE, has averaged a little over 30 MPG over the past year we've owned it. Granted there's been some times of low economy during break-in. But still, its EPA rated 26 city and 35 highway, so that 30 MPG is relatively good as its a mix of driving. And it has actually been recorded as high as 38 MPG on one long trip to visit her brother in prison. Over 400 miles on a 13 gallon tank, not bad at all.
I usually keep them inflated a couple pounds over the door sticker. The Ion calls for 30 PSI, I like 32.
As far as my trep, I got new rubber last May, and went with Uniroyal Tigerpaw A/S 6000's. An all-seaon tire with a 60K mile ? rating. Gotten me thru the snow thus far, and seem to be wearing fine. I went with an "S" rated instead of "T". The "T" was a bit more, and I don't drive that fast. The only thing I don't like is the max pressure on the tire is 35 PSI, and I like to keep mine around 33.5 or 34. I don't like my trep when they are at 32, it seems sluggish and lazy on turns.
