Need 18" tires with good MPG

I need to decide soon on a replacement for my stock '13 DC Limited with 18" wheels. I'm staying with the stock 265/60R18 size, and am looking for a tire that looks aggressive, yet still gets close in MPG to the stock Bridgestones. I can go to NTB, DT, or Wally World just as easy. I've been reading a lot of tire threads but not seeing a lot of real-world experiences with the 18" tire size and am thinking that the bigger tire size of 18" will result in a much heavier tire, hampering MPG and so I need to keep an eye on that. So far I'm liking the Falken Rocky Mountain or the BFG Rugged Terrain, but am unsure if they are P or LT rating... I've read where one rating or the other can make a difference in MPG. What do people think of the choices out there in the 18" tire size?

 

I have hankook dynapro ATM in 265/60/18. Compared to my stock 16's I lost 1-2 mpg.

 

If it's strictly a daily driver and you want the best possible MPGs, stick with P rated tires.

 

Therein lies the rub, I cannot tell if some tires are P or LT in reading their spec's. I'd rather have a P tire that looks aggressive, yet gets good MPG

 

doesnt exist. stick with exactly what u have if u want same mpg or get better tires and lose a few mpg.

 

Check out tirerack.com. They list all the specs and even the weight of each tire. You're not going to find an aggressive tire that's P rated. It has to be one or the other.
