How does the tire load rating affect the total towing capacity of the truck. I've got an '05 LE stock except for the airbox mod. I just had a close look at the Conti's and they are rated at a max load of 2601 lbs.

Question - If you get tires that have a higher load rating 2900 or 3300 how does this affect the towing capacity or does it just affect the payload. So is it worth it to go for a higher load rating on the tires, or does it not make any difference to the overall towing capability of the vehicle since the stock tires are rated at 2601?

The Vehicle load rating (GVWR) will be exceeded before the stock tire load rating is. But I would bet you would achieve better handling while towing near or at the limit using a tire with a higher rating, but expect a rougher ride due to a stiffer carcass of the heavier tire.

Multiply the load rating by 4. This is the max load for the tires. Then subract the truck weight, cargo, passengers, and this is amount you can put on the tongue. 10% of the trailer's weight should be the amount of downforce on the tongue. So a max of 900 lbs if you are towing max.

This means if you have tires rated 2601, you can have 10,404 - 5,400 = 5000 lbs in tongue and cargo weight. However, remember, this is per tire, so weights will vary front to rear. Spreading this out, if you have 7 passengers weighing 150 average each, that leaves you 3950 left. Half of that represents the rear tires or 1975. Take the tongue weight off that, and you are at 1000 or so for cargo in the rear.

Bigger tires will increase cargo capacity, including roof pods, more in cargo area, fatter people (Like Me) etc.

The Armada has a GVWR is 7000lbs (see door jam) = max the truck can weigh fully loaded; tongue weight, hitch, cargo, people, bird poo... everything. Most Armadas tip the scales at roughly 5500# that leaves 1500# to play with. If you tow at the max rating you should have a minimum of 10% on the tongue = 920 lbs. Now you have to knock off about 80lbs for the hitch. That leaves a whopping 500 lbs left for some really thin passengers and a bit of carbon fibre and aerogel gear.
In theory the Armada CAN tow 9200 lbs, but you just have to go by yourself, which of course is not mentioned in the advertisements.
In real life, 7500lbs is really the common sense limit.
