E's max load is 3415. So if I am thinking right my current P tires 4ply hold more then cooper C tires 6 ply. So if I want to get rid of the squirmy swaying problem I have to move up to E range no??. Or I just keep my current tires ???
P tires on a towing vehicle are a significant contributor to sway. A LR D or LR E would eliminate the tv squirm.

The only difference is the C is 6 ply and the E is ten ply. And I think the p-metric is 4 ply. Is it the ply that reduces the sway or the load???

I run the exact same size tire on my Tundra. My trailer weights loaded are about the same as your unloaded weights are. I normally run the P rated (LTX M/S2) tire, and I probably wouldn't want to tow anything more than that on the P rated for sure, but have a 10 ply tire on currently (winter tires - Nokian) and the squirm/sway is virtually non existant, however I do dislike the unloaded ride with the 10 ply's, even with the reduced pressures (50 psi unloaded, any lower and they were getting really warm on the highway)

If so, why do auto manufacturers market SUVs and light trucks, that specify significant tow capacities, come equipped with P-Metric tires? They're being negligent? The consumer is not being made aware by the vehicle manufacturer of the hazards associated with towing with a P-Metric tire? I don't get it. If the aforementioned tires are causal to hazardous towing conditions (sway), why the heck are they being fitted to potential tow vehicles.

Because people want their rig to ride like a caddy LT tires are not conductive to caddy like rides.

I will also guess that the same size LT tire is more spendy.

It could be that a large majority of SUV owners are in for the show not the tow.

Yep, I get that. Cadillac ride is cool. However, where in this equation does the dealer/seller present the buyer with the prospect of hazardous miles ahead (trailer sway) should he/she be inclined to hitch up a TT with the OEM P-Meric tires that are installed on this vehicle?

The P tire will tow but not under the best of circumstances (caveat emptor).

It's like the RV dealer that tells you your 1/2 ton PU will tow a 16,000 lb FW, yes it will but it is gonna be a short ride.

So as long as the tires meet the minimum safe towing standards no mention be made about LT's.
