How much did e loads actually affect your milage

Interested to hear how much e load tires changed your mileage and power. Getting a lot of varying info

 

Here is my experience with E-Loads over the last 6 years. 2018 TRD Offroad, 2WD, 3" lift KD MAX tune from 3-4 years ago. Currently on 285/65-18 Wildpeak RT 01's. The mpg varies a lot depending on how you dive it. I live in the Phoenix area so things are pretty flat around here. On my commute which is 60 miles round trip 98% freeway I can still get a hand calculated 18-20 mpg if I drive mellow and keep it around 70mph or less. 75-80 will drop it down to about 16 mpg. On a road trip with a passenger and say 300-500 extra pounds of stuff from Phx to San Diego going between 75-85 it drops all the way down to 13-14 mpg. The power is just fine. The 1st set I had were Nitto Terra Grapplers and I managed to get about 76K miles out of them.

 

You're going to get a million answers because "e load" is kinda meaningless in regard to your question. Weight and size are going to be bigger factors than load rating. And even then, it's super hard to get any kind of a consensus regarding mpg and either weight or size. Seems everyone's situation is different.

As an example... My mpg stayed the same or possibly got slightly worse when I switched from an E load tire to a C load tire.

 

I agree with the above, it is going to be all over the place due to so many variables. I have always had 265/75/16, I originally had Duratracs in C. when I switched to S/T Max in E, I got almost 2 miles more per gallon. I recently switched to SL rated Wildpeaks (which is considered "B") and mileage stayed exactly the same as when I had E, which were significantly heavier. My tires do stick out past the fenders and I have always wondered how much aggressive side tread impact wind resistance? Duratracs probably had the most agressive sidewall, and the S/T Maxx the least, and the Wildpeaks probably in the middle.

 

The size I'm looking at would be 265/75/16. I know more aggressive tread can impact milage. I guess I'm mostly curious about the impact weight has

 

Tire weight and height will affect your mileage in stop and go situations. Tire width will affect you while going down the road (rolling resistance).

I recently switched from 265/75/16 General Grabber ATx tires to Falken Wildpeak AT4w in 255/85/16. The Generals were E load, the Falkens are C, Falkens are about 4 lbs per tire heavier (IIRC). The combination of taller, narrower, softer, heavier tires have me at nearly the same fuel mileage. Go figure. I do get better gas mileage on the highway at a steady speed but considerably worse into a headwind.

Long story short, I'm anywhere from 15 to 19+ MPG, depending on the variables on any given day.

 

Oh, I'll have to wait a minute, but I think the C load sidewalls will be more compliant in winter weather...just a guess.

 

I have 60mph speed limits where I live, I found very little difference between a 45lb , a 51lb tire and a 61lb tire AT (KO2s and Falken AT3W) for mpg. Driving conservative I get between 18 and 20mpg on road trips.
I thought there would be a bigger difference. If your commute is 70mph or more then things are going to go in the shitter!

 

I recently went from cooper st maxx 255/85/16 to cooper road + trail 265/75/16. This was to help with mpg and power. The st maxx were 53lbs per tire while the road and trail are 40lbs per tire. I dropped 52lbs of unsprung weight! The ride is also significantly smoother with the thinner side walls on the road + trails. Load range E tires are not designed for lighter weight trucks like tacomas. If they’re for off-road, you probably don’t care, but if you’re primarily driving on road, you will feel it.

 

E load or C load doesn't matter because some C loads weigh nearly what E loads weigh. Heavier tires will be tougher for the truck to get up to speed but once at cruising speed you'll see little to no difference between the 2. Ride comfort is a whole other story and I firmly believe E loads are way overkill for a little Tacoma unless you frequently kill tires offroad.

 

Been running e loads for the last 25 years. Never felt much of a noticable power loss and as far as gas milage i wouldn't know... never checked it and don't plan on starting. Another thing... never had a flat with e loads. Most of those years has been with bfg a/t 265/70/16- 265/75/16 & now toyo r/t 275/70/17. Truck has 2" Icon stage 8 and tracks like a tank... no body roll and feels/drives way better than stock. E loads are a rougher ride but that's how a truck should feel imho.
