Many older small cars have their engine rpms way too high, at highway speeds. Taller tires will never reach "dimiinishing" returns. On my motorcycle once, I changed the "sprocket/counter sprocket set" ratios by 15%. My MPG went up 10% into the 75+MPG region. Yet, I was able to accelerate past the designed "top speed" of the cycle, well into triple digits. I think the cycle would have continued to accelerate, till it destroyed itself...... & me, with it.
