Expedition Tires for Towing

[07navi]

Tires are not "over-inflated" as long as their cold tire pressure is at or below the Max on the sidewall. Pretty sure the P-metrics on mine have 50psi (52psi?) there.

One can always kill a fly with a hammer -- or run LT tires on a SUV.

"Flimsy tires?"

-- Chuck

Yes 35 max and some extra load ones go to 44 PSI. The best riding LT tire is 50 max (what the trailer people need.)

 

[chuck s]

Nope. Maximum tire pressure on my P-metric tires is 51psi. GAWR is handled at 35psi with these tires. Since the tires are also rated at 2756 pounds each (5512 for the pair) they can easily handle the GAWR of 4300 pounds noted earlier.

The truck and these tires are fine for towing.

If I was towing on a regular basis I would have gotten LT type of tires. But for 2-3 camping trips per year the P-rated tires are just fine. That's with a 30' camper at 7,000 pounds with a WDH hitch and the 22" tire setup. I pump them up to about 45 psi when towing. Well within the Ford specs. To the OP - check the tires your trailer came with from the factory. Likely Chinese-made junk tires. That is your weak link in the overall setup. Invest in some Goodyear trailer tires for peace of mind. Good luck!

IDK why those are 51 (look it up) but they are still car tires. Are you sure those aren't LT tires?

 

[chuck s]

Photo is minutes old. They're P-metric tires that came on my new '17 Expedition 2 years ago. Similar tires were on my '07 Expedition. That's what comes on these trucks.

Added: Just walked down the garage and checked: The Maximum tire pressure on the tires on my lil' Honda S2000 is the same: 51psi. No one would mistake either the car for a truck or tires for a light truck tires. These are, of course, flimsy P-metric tires (255R40/17).

Look up P rated tire max pressures on google to see what those car tires are rated at.

B-McD,
I echo your comment about the junk Chinese tires. After 2 blow-outs on the first trip with our New-To-Us RV, I replaced all 5 tires with Goodyear Endurance and upped the load range from C to D. I'm also doing 2 things that the previous owner (who otherwise took phenomenal care of the trailer) did not do--the tires no longer rest on the ground and are covered.

It is with concern for similar tire issues that I initiated this thread. ALL the time spent fomenting comments are greatly appreciated.

You guys need to be listening to 07navi. If you've ever towed a trailer in a little bit of wind on the highway or gotten some trailer wobble from a tractor trailer passing etc., you'd understand what it means to need a good side wall. I would be towing with E rated if I could, but they don't make them for 22" wheels. It's not just about the tire weight rating. It's about the sidewall ply that helps stop sway.

Exactly, if I used P rated tires instead of E rated light truck tires on my 8,000 pound Excursion it would be squirming all over the road. Those LT tires are heavier duty all around.

That's your sidewall...…...look them up.

C'mon, Chuck. You know those tire engineers don't know what they're doing, just like engine designers and engineers...always telling us stupid ways to maintain our cars when we have google to tell us the right stuff.

Chuck might have 51 max psi rating (probably LT tires) but what about everyone else. It's all in google...…….look it up.

 

[HawkX66]

P rated tires that have 50 lb pressures are usually low profile tires from what I've seen.

C'mon, Chuck. You know those tire engineers don't know what they're doing, just like engine designers and engineers...always telling us stupid ways to maintain our cars when we have google to tell us the right stuff.

C'mon, Bob lol Yes, Firestone engineers really knew what they were doing when they had to recall all those tires years ago due to rollovers etc. It's not always about the original engineers. Execs end up making changes. Why would they do that for a tire? "You'll save gas with these tires!" Marketing. The only P rated tires I've seen that were 50 psi are performance tires. Low profile type etc.
My point, just because they say so, doesn't make it so. JMO of course...

 

[chuck s]

Have you even looked at the sidewall of car tires? The data is all there.

Why would google know more about the maximum tire pressure on the tires on my truck than I confirmed yesterday -- and furnished photos? For grins here's the maximum load and cold tire pressure from the rear wheels of my lil Honda S2000. Yep 51psi (again). 1477 pounds capacity.






I really don't care if anyone wants to run truck tires or change their oil at 3,000 miles. Overkill always works...but it ain't necessary.

What does your Honda have to do with whether or not you should run LT tires on an SUV? My bicycle tires take 65 psi. Must be great for towing... Not very good logic.

Again not everyone has P rated tires like yours and I am thinking they aren't P rated. According to the net there are no P rated 51psi max tires out there (maybe some low profile ones). Actually LT rated tires aren't overkill for heavy towing. Nobody mentioned 3k oil changes.

Guess those tires on my Expedition are imaginary... 'cuz the net says so.

The 51psi max pressure tires on the Honda are P-metric too, but, alas they must be imaginary as well. Nothing to do at all with towing but they're P-metric and their max inflation pressure is 51psi -- even though that's impossible.

This was about towing, not your low profile tires.

Chuck apparently my Michelin LTX MS/2 P rated tires on the Expedition are imaginary too. Much like yours they read 51 PSI max.
