    Load range E factory upgrade question

    Has anyone opted for the LR E tires from the factory? If so, what brand tires are they? I once thought they were installing the Goodyear Wrangler Silent armor tires, but that was years ago.

    Seriously, I wouldn't put Goodyear on a wheelbarrow for fear of it wobbling. We had Silent Armor and MTR's on work trucks, had to be the most annoying ride over 40 mph. If they weren't flopping in the winter from flat spotting overnight, you could put a cup of cream in the cupholder and make butter after 1/2 a mile.

    I can't answer most of your questions but from my experience load range E tires are awful heavy and kill mpg in half tons at least in my experience. I put them on a 2015 f150 with a 5.0 motor. Went from 18.5 19.5 mpg average to 14 and 15 mpg average.

    Is that load rating really needed on this halfer? Our tow and load ratings are low.

    I guess I don’t agree with anyone so far. I like E’s for the puncture resistance, they wear better, and while the loads we carry are within the rating of P tires LT’s do it much more confidently. I have also never noticed a difference in fuel mileage. Definitely not a drop from 19 to 14 lol

    What gearing are you running. In my old f150 I had 3.31 and that's exactly what happened. My brother in law has 3.5 ecoboost he had the same results. The f150 tire stock was 38# and the falken tires I put on where 65# 285/65/18 I lost 4 mpg

    Edit granted that was going to a bigger tire then stock.

    What was the stock tire size? I feel confident it wasn’t 285 65 18. Probably didn’t correct your speedometer/odometer for the correct tire size either did you?

    My truck is 3.55 rear end.

    MAS stock was 275/65/18 so slightly bigger. At that time Ford couldn't correct for tire size changed. Unsure if they even can now. My brother in law stuck with stock size in LT load and had pretty close to same results. A 285/65/18 tire is 32.59 tall stock size is 32.07 tall. Width was less then 1/2 wider. Speedo was only 1 mph off.

    My 16 tradesman came stock with LT 265/70 17 Silent Armor. I keep an eye on the pressure and rotate at 5,000 mile interval. They are serving me well and my mileage and ride are as expected.

    After a year with the GY I replaced them with Coopers HT3 All weather highway E rated tires. I even went a bit wider to LT275/70R17. They are slightly bigger in diameter by 1/2 inch and that will knock your mileage down 1-2 % because they will turn slower, until they wear some, but it's a very small amount. Yes they are heavier.

    As for the ride, I'll tell ya, it's hard to tell any difference. I run the tire pressure at 65 psi (80 psi is max), the ride is still very good, with a nice firm grip on the road.

    AS for mileage, I really haven't noticed any difference. I can still get 32-33 mpg, average is the same as last summer, 24-26 mpg running around town.

    For highway tread, they do well on snow/ice.
    Cheers
