bfg m/t gas mileage

[RavoHimself]

so i'm looking to either get a 32x11.5 or a 33x10.5 tire. either bfg a/t or bfg m/t. how are the m/t's on gas mileage. also how loud are they

i have 32/11.5 km2s on mine and they hum pretty good but not as bad as other mud tires

 

[RavoHimself]

well how are they on gas

I have a set on my super duty and when i bought them they were supposedly a month old and now i have put 30k on them and there is still a good quarter tread left i'm very happy with them...............

Anytime you add larger tires then stock your stupid gas milage goes down. Nobody on this sites gets 24 mpg with 33-35 inch tires. Some tires (AT for instance) will not really give more or less then mudders. Mudders are noisy compared to AT tires and maybe a bit less gas milage. But every body's truck on different tires will vary. Google the information if you can't figure it out, Bro. That is what I do a lot...lol

Besides the size, there is rolling resistance. An all-season has less rolling resistance than an all-terrain which has less rolling resistance than a mud-terrain.
On my Sport Trac I replaced the stock all-seasons with all-terrains last year. Same size as stock. I instantly lost 2 mpg on the highway according to the digital mpg thingy in the dash.

Careful with the assumptions there... I get pretty close to that with my BII. (22, occasionally 23 MPG). Someone with a 2.3L probably would have no problem getting 24 if they've geared correctly for the 35s.

However I don't see a tire's tread itself having all that great of an impact on gas mileage. The design of the tire's carcass will have greater effect (especially if you're comparing bias-ply to radial). BFG MTs and ATs seem to be pretty much the same tire aside from the tread pattern.

I have pre KM 255/75R17 (about 32") BFG MTs on my 90 Ranger 4x4 with 2.9L, 5 speed and 3.73 gears, I get about 18-19 mpg in mixed driving. I would probably top 20 if I were driving at a constant highway speed (55-60 mph) for any measureable distance.

The noise wasn't too bad when the tires were brand new but after 20,000 or so miles they are starting to be a bit noisier, nothing too bad though yet.
