OK somebody raised the max psi on some tires, still nothing to do with towing.

Merely two personal examples to rebut your claim that 51psi maximum tire pressure means I had LT tires on my Expedition 'cuz no P-metric tire can have that max pressure. Turns out I have them on my S2000 as well.

You already said that. Either it's a coincidence the C rated LT tires have exactly 51 psi max pressure or the makers of P rated ones are trying to match it.

lol @ saying P rated tires for the Expy are stretched to the max. I’ve never seen a car with 255/70 tires. Love my Michelin LTX MS/2s, they do just fine and are P rated.

That's what came on my new '07 and they seem to be nice tires...……..I don't tow though.

They are a solid tire with great reviews. These cost me more than the LT tires I originally ordered.

I was glad to see those LTX tires on it when I bought it a month ago but now I have winter tires on some Boss chrome wheels that I got all for $70 locally. I put Nokian Nordman 7 studded SUV 275/60r20 tires on them (one size larger than the LTX's that came with it). I do tow my snowmobile but it doesn't know it's back there.
So, I've been trying to figure out what rating my Michelan MTX tires are? It doesn't seem to say "P" rated or anything like that anywhere. I'm assuming because their max inflation is 42psi that is what they are?

Yes, the lowest LT max pressure is 41 psi for the C rated, 65 for the D, and 80 for the E rated.

Defender LTX tires are light truck tires.
I don't see the max pressure notation on the tires but my eyes ain't that good.

Your Defender LTX say the same thing on Michelin’s website as my LTX M/S2 tires....I believe they are both P rated tires. For 20” wheels they only offer the Defender, for 18” wheels they only offer the M/S2.

I would say I've got about 50%-60% life left on the tires. But after reading here and around I'm giving serious consideration to upgrading my tires. I do a lot of heavy towing, most of the time at the Expys cargo limit. I use WDH and pack smartly, but I think some LT tires might be a better option.

They probably name them LTx to throw you off. If they don't have the LT before the numbers they aren't LT tires.

If you tow heavy a lot LT tires won’t hurt when it comes time to swap them out

Let us know the difference if you do.

Lots of opinions. Since I always do what I can to avoid problems, I'll probably do as some recommend and upgrade to a tire with a greater load index, perhaps sacrificing a bit in ride comfort.
Geeee......I can go faster too! Joy of joys. Alas...When towing, I limit my speed to 65 ish.

I liked my Goodyear Trailrunners. They had the higher weight rating. The tread was a mix of a highway tire and an offroad tire. I did run 50 psi in the rears while towing per RV dealership's recommendation. You have a 20" rim, so maybe that might not be necessary. During the off season they were great in the snow. Far better than other vehicle I have ever driven on in the snow. On my 2003, the weak link was the original shocks. I had a similar setup; 2003 XLT with a 2018 Springdale 270le. 7000# empty, 32ft, Reese Dual-Cam WDH.

The Michelin LTX M/S LT275/65R18 tires on my 2013 ran 110k miles and still had some life left. Expedition definitely towed better with the LT tires.
I’ve had 4 Expeds since 2000 and all of them had the P series tires replaced with LT. No problem.

Just my point; P rated tires are not good for towing, squirmy, squishy.

I tow a 32' TT with a 875# tounge weight and while it towed fine with P rated tires, my Michelin LT tires I put on at 55k miles tow better with a stiffer towing feel. I wouldn't pull off P rated tires with 50% life left, but I would go from P to LT if I had less than 20% of life left and was about to get in to camping season (which is about when I did mine)
