And that's just me......
Another member with a scion box tested 3 different tires AND rims......

1. It's a taurus.....not a porsche.....why are you corning so hard.......please.
2. If you really want to ricky race....get some 45s or 40s. That's cornering.
3. (As has been discussed at length...) larger diameter tire will produce lower rpms at cruise. period.
4. Going up in rim AND tire size becomes more complicated because of additonal weight.

2002 infinti Q45 Sport...factory 245/45/18 on alloy...upped to 245/50/18 better mpg
2006 Kia Sportage FWD V6 EX .....factory 235/60/16....upped to 235/70/16 better mpg
Also, kia feels MUCH better on the slightly larger tire.
