I've got load range D tires that state 3000 lbs. @ 65 psi. does this mean they will be able to pull my trailer which is 7100 lbs dry weight? Or do I need to go to load range E which are 3450 lbs. @80 psi? I was under the impression that you multiplied the number of tires 4 X the stated lbs. 3000. If that number 12000 lbs. was more then your trailer weight 7100 lbs. your tires were alright for your load. Have I got this right or am I off base. I'm pulling with an Excursion v-10 4x4 and Equal-i-zer hitch system.
I use D also which came with the truck. I would expect it to tow as advertised within factory loading with the factory tires. I know others will tell you go to E but harsher ride and may or not make any difference. I only tow a 6000 boat + trailer and supplies and it is not an issue for me. Jim
D-rated tires should suffice if pressures are kept up to snuff. Bear in mind that Ford recalled all of the D-rated tires to replace them with E-rated tires. The D-rated tires themselves were OK, but Ford realized (late) that D-rated tires weren't enough for the X.

You are right about the pressures. I keep the d's on 60 PSI all the way around. Jim
Whats real scary is most of the used ex's on the car lots and on Ebay have 'C's on them. It's cheaper when the dealer throws new skins on to unload them. Be aware.
When I bought the Ex last week it had newer Dayton Timberline AT's on it and I had read that they were good tires so I did'nt want to change them. I think I will air them up to max 65 psi and take it slow and easy from Denver to Reno. Now my only problem is what to buy for the trailer tires on the 34? After reading all the old posts I'm as confused as ever.

You actually need to go by axle weight. Those D's on the back will support (by rating) 6000lbs. (3K*2) Let's say you've got your truck up to total GVWR of 8900 and the front to rear ratio is 50/50. That is still under what you can carry (by rating).
Keep 'em at MAX sidewall pressure and you should be just fine.
The tire's weight-carrying ability really has nothing to do with the ability to tow a trailer's weight. At least in the way your post is worded.
It does come into play but the tow vehicle's tires need to support the weight of the truck PLUS the tongue weight which is usually 10-15% of the trailer's loaded weight. It can be a bit more since you are using a WD hitch that transfers weight to the front axle, too.
Another thing to be aware of, if the tires were replaced. Make sure they have truck valve stems. If car tire stems are used, they are rated for up to 60psi pressure.
I lost a tire after having a tire replaced, along with a light duty stem. This was at an OEM Firestone dealer, on my '00 with the Firestones. The stem blew out between Flagstaff and Winslow, AZ. I then S... canned the 'D' Firestones for 'E' Michelin LTX M/S's. Great tires. I'll put them on my '05 when the Pirellis wear down.
Thank you for the answer Monsta. I have read alot of your posts over the last year while looking for the perfect used Ex. and have learned alot. When I was young and dumb i was a bartender in Makaha on Oahu. Those were the days.....
Thanks Btravelen I knew I had to check on them but forgot. Soooo they look like your basic rubber ones so I will have them switched out. Thanks for the heads up. I too wanted LTX's but these Dayton AT's look new so I guess I'll keep them.

How can I tell if it is a car or truck valve stem? Jim

Want to know something scarrier? When I got my X, They didn't even have LT tires at all!! Passenger Car tires instead.
