Right Tires

I know this question must have been answered several times, but I after searching the web I can't find the answer.
I need new tires for my truck and like the right parameters so I can find the right tires.

I have a 2000 F-250 2WD 5.4L Auto towing vehicle.
The 5th wheel is a 30' 2005 Jazz Thor with a maximum weight of around 10000lb.

My best bet is that I need
- Load Range E or better
- Load Index 123 or maybe a bit less
- Speed Rating K or better.

I don't want to buy too weak tires and get in trouble,
so any comments about the right values would be appriciated.

Thanks and sorry for the repeating question

Thomas

    Right now I have the LT265/75-16 on the truck. The former owner did a lot of stupid thinks to the car, like installing a performance chip (the car runs great now with the chip), so I think the tires are too big too.
    I will buy the standard 235 tires.
    Since I drive only highways, I will stick with standard highway tires.
    The E rating seems to be a fact, but I am not shure about the load index.
    The cheaper tires have 116 and the better one 123. Not shure if I spend the extra money on 123, any suggestions on that?
    We use the truck and trailer only 2 months per year for vacation, so I will never drive 50K miles, so the lasting of the tires is not important.
    I am more concerned about the safety aspect...


    Just remember the tires carry the lives of your family!

    The 265/75-16 E's will have a 231# greater load capacity than the 235's. The larger tires could have been part of an optional camper package.

    I would be looking at Michelin LT M/S2+, shop around for the best price, Costco, might be an option.

    The VIN sticker on the Drivers door jam will list the minimum size to carry the GVWR of the truck.
  • The 265/75 or the 235/85 both have plenty of capacity.

    The trucks current wheels width will determine if you use the 235/85 or 265/75 tire.

    The 235/85 is a narrow tire = a narrow wheel.
    The 265/75 is a wide base tire = a wider wheel.

  • What size and load range are your present tires ?

    Stick with a LT E tire.
    Ford came OEM with LT235/85-16 E which takes a 6.5"-7" wide wheel for years but started using LT265/75-16 E tires with a 7.5"-8" wide wheel.

    A tire dealer can help you with fitting the right tire size and load range tire for your trucks wheels.
  • I just put a set of Mastercraft HXT tires on my Tundra.Mastercraft HXT
    I've only driven a few local miles on them so far, but I haven't pulled the trailer with them yet. I've had several different sets of Mastercraft tires on different vehicles and they have always served me well. They're a good tire at a reasonable price.
  • I don't think you can go wrong with any of the Michelin LTX tires, depending on your driving needs.

    Expensive yes, but IMHO well worth it.
  • Well, there's a few pieces missing from your requirements. Will you be driving through snow or icy patches? Will you be driving mostly highway? Or will you also be going off the paved road every so often? Otherwise, you will want to look primarily at highway tread tires. Or if you do go on dirt roads or need some snow traction, you may want some all terrains. I would avoid anything with large lugs/voids as those tires (typically Maximum/mud terrain tires) tend to wander more when driving on the highway and also cause some high speed drone.
  • I've run many brands of E rated tires on my own and company pickups. Never had one fail.
  • I have 'E' rated BFG Rugged Trails on my F250. Was the original stock tire and replaced at 55K with same tire. Now have 80K on truck and new tires are just getting broken in. No complaints.
