ive got...... 185/65/14 *cough* and i only get 28-30 on 87 octane, i did a 2 month long test with 87vs93 octane, i averaged 29 on 87 and about 32 on 93 .
when i ran around with my bald 195 azenis i was gettin like 34 mpg on 93 >.<, damn skinny tires. i'd figure it'd do better with skinnier tires but i suppose not

Before Dallas Trip No freeway and a bad tire: 29.7 mpg.
Dallas Trip and driving like a maniac through the burbs to avoid rush hour traffic and new tire: 31.2 MPG.
Ride Home all freeway between 70-75 mph and 3000-3400 rpm 36.8 mpg.

Rolling on bald, underinflated 205/40/R17s, 30mpg highway averaging 80mph, roughly 4000-5000 RPMs with my tranny.

I got 33 MPG on my last tank.

i finally checked my mpg last week and it was only 25.. but i guess thats better than some cars
