Gotcha! They were on my short list of tires but not sure i really want a Load range E. Wish they made them in a D. What pressure are you running in them?
I promise you, you do not need an E. No f150 of any sort needs an E.
E is a load rating, meaning how much weight the tire will handle. Even if you tow a shit ton the vehicle tires only carry the tongue weight.
A properly equipped F150 is rated to tow 14000 lbs and haul 2000 lbs. And does not come from the factory with E load tires. (Federal law requires tire rating to equal/exceed vehicle performance abilities)
A raptor is all but 1/2 that (7000lbs 1000lbs) and comes with C load rating which is actually a higher rating than the non raptor rated for 14,000lbs/2000lbs
The gains are 0 and the losses are quite a bit, more cost, worse MPG, possibly worse braking and worse ride.
I hear durability (side wall) and I would need a see a dozen plus tires driven through same environment. one sliced sidewall doesn't prove anything.
(Once I find a picture I will post, E load )
