E rated tire on 2016 265/75/16

I have no experience with these heavier rated tires, by switching to an "E" rated tire just basically one inch larger than the stock tire, how bad will it affect my mpg's and road handling? I have a 100 mile round trip commute but regularly use my truck as a weekend warrior. Any help is appreciated.

 

Had them on my 2006 for 10 years with no issues. Milage wasn't great, but not sure I would blame the tires. (Goodyear Wrangler's)
I don't think you have a lot of choices in that size with regard to ratings. Wanted that size on my 06 and had to settle for the "E"s. Way overkill, but loved them.

What are your BFG KO'2 rated that you have on your 16?

 

I am running 265/75/16 C load duratracs and I lost about 1-2 mpg, getting about 17-18 on average right now. I know its not an E load range but gives you an idea.. I think I would expect at least 2mpg loss with an E but it also depends on the tread pattern/overall rolling resistance. My father runs Cooper At3's in a 265/75/16 E load on his 2nd Gen and I don't find them to ride stiff or rough at all. Also didn't notice any appreciable loss in power.

 

Your truck comes with P load tires, which are the lightest in the spectrum. E loads are the heaviest and suited for an F-350. I would recommend avoiding them. With heavier rotational mass you will see hits in power, mpg, and braking. Tires ratings go: P<C<D<E

I would try to find a lighter C-load tire if you can. Letting us know what type of tires you are looking at may help. Duratracs for example come in 265/75R16 in C-load, but KO2s only come in C-load if you go to 17s and run 265/70R17.

 

Very helpful, thank you!

 

I would think the load rating wouldn't have as much effect as diameter and width. I know the tires would be heavier but I wouldn't think it would be very noticble. The + side to e rated tires is you will get nearly twice the mileage out of them. And they would be more puncture resistant.

 

I think that the E rated tires are like 10-153s heavier than the C rated versions depending on the brand. That's 10-15#s un-sprung weight. Not needed for an LT IMHO and will hurt performance and MPG. Try and find a C rated tire... there's a lot of good ones out there.

 

I have the BFG KO2 E rated tires. They are stiff, rougher ride from the stock tires. I did see a hit in MPGs

 

A mile or two per gallon??

 

E's here, I hate flats and always used to seem to pick up a nail every few months. Last one I had was on the side of the highway in the rain and dark, over 8 years ago. Since then I only run E's on everything regardless, it's worth the trade off of HP and MPG loss, which is minimal. If you offroad regularly I highly recommend it for the peace of mind as well. Changing a flat is easy I know, but being inconvenienced on a trip or worse pulling over in a possible dangerous spot to change a flat with my wife and child in the car and being side-swiped by some idiot not paying attention.

 

How much of a hit in mpg's did you see on your 16'?

 

I've been running E rated 285/70/17 BFG KO2s for a little over a year now and there are definitely pro's and con's to them. Not very great for highway, considering the stiff ride and the loss in power/mpg's (from the weight of the tires). But the main reason I got them is for 4wd trails and forest roads. They take a beating, between running over branches, roots, sharp rocks, being pinched between roots and rocks. I've had sticks wedged between the tire and the wheel before and still never lost any air. I would say if you don'y do a lot of 4wd trails, and its mostly highway then go with the C rated tires. But for off roading i would suggest the 10-ply E's

 

My dump trailer has 235/85/16 load range G 110 psi tires. Load range E is pointless and useless for this truck but that doesn't stop Taco owners so why not just get Gs?

 

A nail is going to go through a tire, regardless if it is C of E.

Not discounting that Es are more durable, but I've run Cs through all that in the trails of the PNW for 10 years and never had a flat. Tire choice also has a lot to do with it. Certain tires are known for having vulnerable sidewalls that will puncture/tear, while other tires are specifically designed with reinforced sidewalls that are puncture and tear resistant.

Example, check out the tire sidewall test at about 0:46 in the KO2 video. Same tire load rating, different design, different results. Yes, if you buy a lesser designed tire you can get them in heavier E-load to compensate. But doing homework to get a well designed tire that fits your needs without adding a bunch of rotational weight is a better approach.

I lost about 1.5 mpgs coming from a 265/70/16. I do not feel as though they ride stiff. I run at 30 psi and get consistent 18.5-18.9 mpg, 80% highway driving.

 

@crashnburn80, very informative, thank you. I may lean toward the ko2 c rating now but I guess will have to stick with stock tire size of 265/70/r16 due to no c rating at the 75 tire size.

 

I have 265/70/17's on this truck. I can get them in C rated. The TRD wheels are 17's

100% agree. I have friends who run C rated tires and have never had any issues on any of the trails we run. Specifically a month or so ago a friend and I both did the Naches Pass Trail and he was running C tires with no problems. Sidewall does matter a lot, and the KO2s would be solid in a C rating. And yes, a nail will puncture a tire no matter what the load rating is haha. For me I know that my truck is pretty heavy and will only get more weighted down so the 10 ply give me a lot of security especially at 15psi.

 

whatever you say BRO
