Goodyear TT - Gas Mileage?

[Larry Davis]

I'm at 50,000 miles on my Geolander 900's - and hope to get
another 5 to 8,000 out of them. I have no complaints with the
Yokohamas, but have read many rave reviews here on the GoodYear
Triple Treads, so am considering switching to them when the time
comes.
But several reviews (by Subaru owners) on TireRack
claim that the TT's give reduced gas mileage compared to
the Geolanders.
Those of you Subie owners who are using TTs - did
your mileage go down with them?
Thanks,

2004 XS, changed to TT's at 17000km. I log every tank, every cost on my
vehicle. There was no change in mileage outside of roughly 2% difference in
tire size. I get an average (combined city/hwy/logging roads) of 9.046
litres/100km. Best (mostly hwy) 7.4 litres/100km.

2% up or down from the stock rubbers?

the TT's are roughly 2% smaller diameter so 2% lower mileage.

I have them on my 2002 OB with no noticeable difference. Great tires
though.
