We get plenty of tire threads on the forum and I have searched around but wanted to ask a specific question. For those of you with a F150 or Ram / Chevy 1500 who switched from stock tires to the same size Toyo Open Country - did you see an effect on mpg?I have read a lot of good things about the tires and may run with these but wanted some real world feedback on mpg.If you have experience with this would appreciate any feedback you may have. Would also ask you mention what your stock tires were before swapping to the Toyos.Thanks,Stu

Sometimes when I am standing at the highway, waiting to cross the road, a four by four will go by, large lug tires on all four wheels, and it's loud; much louder than a mud and snow combination.Noise takes power to produce. That's why they make cars more and more streamlined. Sleeker and quieter gives better mileage.Having said that, if you like your Toyo's and take them into places where the lug tread will be more fun, who cares about the mileage.

Which Toyo Open Country tires are you talking about? The M/T, R/T, C/T, or the A/T 2?

Which tire? The Open Country comes in different sizes and tread patterns.I will add that when I changed from Michelins with a hwy tread to BF Goodrich KO2's I lost about 1+mpg. I have a different truck but it shouldn't matter.

He's probably referring to the AT2, and if he is that's not an overly aggressive tire. IMO an AT tire is ideal for a pickup - good in snow and good enough offroad in most cases, but you don't compromise too much on-road or with treadwear. Very good tire, imo. I would guess it's heavier and has more rolling resistance than the stock tires so it might ding your mileage some, but it's a worthwhile trade.

Toyos are some of the heaviest tires on the market.

I updated the title to clarify I am looking at the AT2 which is a pretty modest AT tread. They have a good reputation as general purpose truck tire and are supposed to run pretty quiet.

As for weight the Toyo is within a couple pounds of my stock tires. These are all E rated (I run the max payload version of the F150).

Rolling resistance and impact on mpg is not obvious so that is why I am asking for some 'real world' experience.

Thanks,
Stu

Not an F150 but I've run Toyo AT II's on a Highlander and current PU.
No noise or mileage drop noted. I like the tires.

I had a set of the AT's and they are not loud (the MT's are though). They are extremely heavy though and that will cost you some power and fuel efficiency.

I very much doubt there would be a noticeable difference outside controlled laboratory conditions. We ran the M606 Open Country on logging company vehicles, they were decent on the highway with good traction off road and the only tire we could find that stood up to the abuse those clowns dished out. Mind you, fuel economy was not one of our criteria.

Since you already have LT tires, you probably won't notice any difference.

My friend runs them on his work F150 EcoBoost, and still averages 17+ MPG overall, with lots of gravel forest road driving (he words for a timber industry vendor).
