You probably want at or mt with that lift, if you went to michelin defenders you would probably increase that by 2 mpg's, or any less aggressive tire and run top psi. But it wont look as nice, so what is more important looks or 2 mpg. We went aggressive on our SUV, we lost 2 mpg. We had an idea that would happen, but did it anyway for security reasons, the wife now travels to forest by the bay, so the roads are wet, We knowingly opted for less mileage. Most guys know if you opt for a lifted 4x4 with big tires it wont beat a prius at the pump.
However, there are issues with all of those trucks getting the high mileage, first is upfront costs. But that pails in comparison to everything else, you want a hybrid truck for 20% more mileage, I sure don't. Battery pack will likely exceed value of truck. The list of things wrong with the eco diesel is so long they are discontinued nest year. So if it makes you feel any better, this choice for a truck despite the mileage is still a real good decision for the long run compared to the endless issues with other options. Lease a civic if you can if the cost difference goes over 300 a month. I must say I do prefer the 29mpg's we get in the rav 4, we take it everywhere when we go on vaca unless we go to snow country.
