Gas mileage and tire choice

Looking at tires right now. I will be staying stock with 265/70R16s. I really like the BFG ATs, and I've owned them before, but they only come in LT sizes, not the factory P rated size. Since I don't need the extra load capacity over the P rated, I am concerned about added weight and the effect on MPG.

Can anyone comment on fuel mileage with the BFG ATs on a completely stock 2nd gen V6 4x4? Or any other high quality tire that has a somewhat aggressive tread like the BFG AT?

Thanks

Joe

 

MrTRD is running the BFG KO's and his mileage is terrible... like 11-13mpg. he is running 295's though. I am running 255/85R16 BFG M/T KM2's and I still get 16-17 mpg average.

 

i have duratrac 265/75 16 E rated, they are heavy at 54 pounds a tire. I have them so the sage brush doesn't shred them as easily. I get 17 when I find good gas and 15 when i run into bad gas. Those are winter gas numbers so add an MPG or so for summer. I use a scanguage to track my mileage and reset at each fillup, I try to go to the same exact pump handle. I do have a 24" magnaflow muffler welded into the stock location which gave me ~2mpg.

I know I don't have bfg's but my point in posting is don't get too wide of a tire or tall and inflate properly if you want good gas mileage.

 

Thanks for the replies. Kind of confirms what I thought. I'm getting 15 in town, 19 highway right now. That's actually a little better than the rating on the window sticker. Sticker was 14/18. And we have ethanol in our gas year round in CA, so I think I'm actually doing very well with the p series tires that are on it.

Has anyone gone with a skinnier tire? Maybe a 235 or 245 width? I know we are only talking an inch or so nominal difference, but my off road use is pretty rare, and that might be an option. I can always air down at the beach.

 

I havent noticed any significant mpg loss with my 285 bfgs, but I dont do much highway driving, and im also a 4x2.

 

For the same reason, I went with the Mickey Thompson Baja STZ's. The P rated 265/75R/16's ride great, they have minimal road noise, look good and have worn well for the first 8K. Very happy with them. And the best part, Price- $600 delivered to my door with a $50 gift card. Then went to wally world, got the lifetime mounting and balance for $47, so for basically $600 OTD it was tough to beat! Plus I sold my Dunlops which wore well for $100 with 35K on them!

 

Mickey Thompson......not a real popular brand around here, but I'm not into popularity......thanks for the recommendation! Been doing a little web browsing this morning and also found the Cooper Discoverer AT3 comes in P series sizes. Right now it's between those two.

Thanks to everyone who took the time to respond!
