One of the few things that I dislike about my '99 Celica Convertible is that the gas mileage isn't as good as it could be. The 1997-2001 Camry, which had the same engine, got 3 mpg better on the highway with a 5-speed than my Celica does with a 5-speed, and the Camry weighed about 300 lbs more! I can only attribute this to the high revs of my Celica's 5th gear. So, my question is, can I achieve better fuel economy with a larger diameter wheel/tire combination? I know it would throw my speedometer off a bit, but to save fuel, it would be worth it to me. On that same note, what would would the tallest tire that I could put on a 16" rim and not suffer from any fender rubbing? What about a 17" rim? Thanks for your help!

Ill have to agree with playr, tune it up. The 5sfe is easily capable of 32+mpg hwy. Plugs, wires, correct timing, proper tire inflation, and a light foot with conservative shifting points (2500 rpms) will get you great mpg.

There was so much JDM trapped inside that box that they couldn't contain it, so they had to put a JDM hole in the box to let the JDM out.

Actually, I already do all of those things. I am currently averaging 32-33 mpg in 85% highway driving. I am just wondering if I can do even better with a taller tire, as I am planning on getting rid of my old stock rims for 16" or 17" new ones.

As for bigger tires, remember that this will put more stress on the engine, causing it to work harder. Guess what? more work = more fuel consumption. Now quit hypermilin' or buy a SMART  Just play'n
