all terrain and mpg?

looking to get new, bigger wheels and tires. Currently have 245, 16 grand trek Toyota gives you if you don't buy trd. I want 17's, possible 265 or 245. Looking at the bfgoodrich rugged terrain but I want something that doesn't suck on mpg. Anybody have any suggestions?

 

More factors than tire size come into play here:

What year is your truck?
Engine size?

 

2015 v6

 

Nice! I can't speak for the 2nd gens, but when I went from stock 29" tires to 265/75/16 Cooper AT's, my MPG went from around 20 to 17 MPG. I just bought a 2003 with 33" AT's and it gets around 17 MPG, too. As long as you're not putting MT's on there or something crazy big, it won't be too bad

 

When you went from a 29" tire to a 31" tire your odometer and speedometer is now off by about 7% unless you have everything re-calibrated When you figure fuel mileage you need to add about 7% to the miles showing on the odometer. You're not as bad as you think.

My 07 double cab 4X4 came with 265/70/16 BFG Rugged Trails, I ran Rugged Terrains for a while too with some 245/75/16 in between. Same diameter, just narrower. Currently running 265/75/16 Cooper ATR's. They are taller, but same width as factory. All have been AT's, fuel mileage has not changed. I get 16-17 in normal everyday driving, 19-20 on longer trips on the interstate. Had I ran a street tire I'd have expected 1-2 mpg better, a true mud tire about 1-2 mpg less.

 

Moved from the stock 265/70R16 rugged fails (37.2lbs per tire) to the MUCH better P265/75R16 hankook dynapro atm rf10's (39lbs per tire) and havnt really seen any big change in mpgs. maybe .5mpg less. But they are not MUCH taller or much heavier at all. But if you were to go with a load range E or a heavy AT / MT tire you can kiss more MPGS away.

 

How are the Hankooks in the snow and slippery dirt roads?

 

Same here with the Hankook Dynapro, went from 265/65/17 stock tires to 265/70/17 Hankook. Mileage just went down .5 but the handling and drive off road is worth the switch. In a heavy rain downpour, they pretty much paid for themselves considering I was going uphill /downhill at 6% grade

 

I have been impressed with them in every situation so far. Limited snow use, but some and they were FAR FAR better than the rugged fails. No real mud use, but dirt n whatnot off road, far better.

 

Hey Helmet. I am looking to buy the same tire same size.. I am all stock.. Do the tires rub at ALL??? Id rather not take flaps or anything off and just leave it stock. Also, how do you like them? Thanks

I went from stock 265/65/17 to Cooper Discoverer ATP 265/70/17 and honestly couldn't tell much of a difference in MPGs or at least my UltraGauge didn't show any difference.

It never rubbed until this past weekend. I did my first distance drive and when I pulled over to rest stations, if I made a really hard turn, I hear very slight rubbing. However, it never does it when I daily drive it and I make the same hard turns in parking garages.

 

I had 265/70/16 hankook dynapro ATMs for about a year. Great tires. I was regularly getting 20+ mpg

 

I just went for 265/65R17 to 285/70R17 (taller, wider and heavy). My MPG before was 20.5 (I drive 90 percent highway like an old lady)... my MPG after was 19. That is just one tank so the loss could be fuel quality or my testing of the lift/tires... second tank went back to 20 MPG but I also adjusted my highway speed from 67 to 63....

so to sum up... expect a bit of change but not horrible. your driving habits will have more of an impact.

I went with 255/75/17 Goodyear Wrangler Duratracs on sport rims. I haven't noticed and mpg loss from stock 265/65/16 tires on factory steel.

 

My experience with oversize tires is that it will slightly change your MPG but not as much as you think.
2011 Tacoma V6 only dropped 1 MPG by going up to nitto trail grappled 285/70r17.
2015 4runner V6 only dropped about 1MPG going to 275/70r17 bfg ko2.
both are much heavier tires than factory and both vehicles have been lifted also. Imo the slight loss of MPG was associated with the lift just as much as the tires.

 

I had 265/75/16 Goodyear MTR E rated and Goodyear Duratrac C Rated on my 2009 Prerunner and saw a very minimal drop from 265/70/16 Rugged Trails. I have stock tires on current truck and anticipate same when I buy new ones.
