Anyone running LT-rated tires on Ford Expedition?

Looking for opinions/experiences on switching from P to an LT tire on a 2005 Ford Expedition.

I am currently running Firestone Destination A/T tires, which are about 3 years old and have about 1/3 of tread remaining. About six months ago I started experiencing a grinding noise in the front when turning. I read that in the Expedition this can occur if all four tires do not evenly wear. I rotated the tires and gradually the problem went away.

Now I am experiencing a loud humming type sound. My first thought was maybe the front wheel hub bearings were going out, but now I think it is just the tires. The A/T's were great when new, and just as quiet as Highway/All-Season tires. However, now the road noise is really getting annoying as these tires wear. I hate to drop another $1K on tires when the A/T's still have life, but I guess I can keep the A/T's and use them as winter tires.

Thinking about going with Michelin LTX M/S2. I know they won't be as forgiving as a P tire, but I'm OK with that. Will probably never air up to 80 PSI, so I don't think I need to worry about the rims handling the pressure (they are stock one piece aluminum rims). Even though we don't have a TT now, we plan to get one within the next year or two. So, do I have anything to be concerned about by doing this?
  • I'd just get some D rated tires. E's are overkill. BTDT on an F150. I've owned two F150's, had D's on one and E's on the other. D's rode nicer and gave the same control as the E's that I ran 50psi in. Got a great deal on the E's is why I got them.
  • What size? My F150 came oem with LT265/70R17-C door says 36 psi, sidewall 50 psi max.

    I replaced my front cartridge bearings myself. Not a bad job and it did tighten up the steering.
  • I ran LT tires on my 1999 and 2003 F-150s. They provided a very stable ride, but I never tried P type. I highly recommend them for RVing. However, find out how much they weigh. I ran a tire that was 20 pounds heavier than OEM tire and performance/fuel economy suffered. The Destination AT and Revo tires are a bit lighter in LT form than most of the same size.
  • I love my 2002 duramax ( bought new ) in every way except one .
    It is a rough riding son of a gun .
    I upgraded the factory 245/75r16 load range E tires for Michelin Highway 265/75R16 load range E on my 1997 vortec 7400 and again on my 2002 duramax .
    I have about 60,000 on these now and they are not to the wear bars yet .
    The Mich 265 made my cornering better .
    I run a little less pressure and at 3415 # payload each i have no concern loading up to the 9200# payload .
    running around weight is about 6800 # .
    I have been shopping tires lateley and thinking about using the softer P rated tires that weigh about 80 % of the load range E tire .
    In the end I can say that these michelin highway tires have been very quiet throughout their life and have cost me no more per mile than cheaper tires that will only go 45,000 miles or less .
