2001 Forester - lower gas milage with ComforTread

Hi,

I installed GoodYear ComforTread on my 2001 Forester recently. Before that, gas milage in city used to be ~20 mpg. But after I installed the new tires, it became ~18 mpg. Is this normal? Or maybe the tires were installed incorrectly? Btw, I like driving with these new tires...my only concern is this gas milage difference.

Thanks for any hints, Boris

Check the tire pressure. The numbers on the car door are too low. I'm running mine at 36 psi all around.

Not too unusual for some tires to provide lower gas mileage in order to get a better ride. I run my Forester at 32/30 which seems a good compromise. Check your tires overnight cold with a good tire gauge.

Similarly, I run my Michelin Hydroedges at 34 all round. Running them at

28-30 drops mileage a few mpg. Plus, I like the handling at the higher pressure -- might be my imagination, but my Forester feels more responsive at the 34 psi setting.

Chances are good that the circumference of the new tires is different from that of the previous ones by enough to change your speedo and odometer readings very slightly. It doesn't take much to alter the readings by 10%

I'm not sure what kind of tire you had last time. But Comfortread has more grip on the road for sure. More grip means more traction means more friction and more gas.
