Are those mileage figures accounting for actual distance traveled and amount refilled? Or just the computer read out? My last tank I went 268 miles (accounting for diameter difference) and yielded 16.2mpg mostly hwy miles. Dash readout was 15.7 or 15.8 iirc. Since I've got bigger tires I'd imagine you might do slightly better. Caveat: K02s run small and I've heard K03s run very true to size. My 35 actual diameter might be pretty close to your 34.
When I hand calculate I get 16-17mpg hwy with the 35s and static lift pretty consistently if I stay around 70-75. Stop and go more around 12-13.
