Our local tire guy convinced the maint guy at work at our Chevy Tahoe needs load range E tires because of the "abuse" that it gets. Keep in mind that it usually only has about 300 lbs of equipment in it and on person driving it.
The first time I took this truck down a back country road at 55 mph (35 psi in tires) I thought the tires were gonna roll right off of the rims. To get anything near the stock handling the tires need to be up around 50 psi, at which point it becomes similar to driving a basket ball down the road, bouncing out of every little bump in the road. I could see maybe using a load range C or D (if needed), but an E is way too much. I have also aired down my tires due to a higher load range and to get better traction off road. I dropped the rears down to about 15 psi in my 97 F150 while the fronts stayed at the stock PSI. I can tell you that after about 5,000 miles, the rear tires were showing much more wear than the front. I have always blamed this on the increased heat generated by lower PSI, but I'm not really sure. IMHO, if at all possible, stay away from E rated tires on trucks that don't NEED them. They have their place, but it isn't on an F150. If you absolutely have to use them on a F150, I would say they need a minimum of 45-50 PSI to get at least half way safe operation of the truck at anything over 30 mph. |

Aren't the stock LT tires load range "D"??
|
If you want the 10 ply tire you and want it to last, you may want to go to 50psi min. If not you may start another topic in a year talking about how your tires are wearing bad. Yes they are going to be stiffer, thats why they are an E tire not a P tire.

Tire ride differences are more noticeable on 2WD trucks because the suspension is harsher to begin with.

E ratings are available on F150's as I mentioned before my neighbor ordered some, much to his regret. |

PSI . max load per tire (lbs) --- . ------------ 35 . 1940 40 . 2130 45 . 2310 50 . 2535 max for load range C 55 . 2660 60 . 2825 65 . 3000 max for load range D 70 . 3150 75 . 3305 80 . 3415 max for load range E |
