There's nothing else to say that I haven't already said.
Your F-150 did NOT come with load range E tires. It came with LT275/65R18C. That "C" at the end of the tire size is the load range C.
Those LT tires were an option on your 4x4. Stock 18" tires were P275/65R18, without the "C" on the end of the size.
P-series are available in three different weight capacities, but those weight capacities are not called load range C, D or E. Instead they are called
Light Load, with max PSI of 35 PSI,
Standard Load, also with max of 35 PSI for weight capacity but often marked 44 PSI because that raises the speed rating without raising the weight capacity, and
Extra Load, 44 PSI.
If your tires are size 275/65R18 without a "P" or "LT" in front of the size, then they are Euro-metric. I'm not familiar with Euro-Metric tires, but I guess that's where the 51 PSI max inflation pressure comes from. Are you in Canada?

I currently have the Goodyear SRA and would like to upgrade to the Michelin Ms2. Just wondering if the sidewalls on the Michelin are stronger than the Goodyear. I tow a 5000 lb. travel trailer. I inflate the Goodyears to 42 lbs. and the truck seems unstable sort of squishy, just wondering if the Michelin would be able to handle the load better. I am using the p metric version . thanks

My F-150 is a 4x2, so the OEM tires are Michelin LTX AS/2 in size P265/60R18. I pump the tires up to 44 PSI cold, and have no problems with squishy-feeling tires when towing my 5,000-pound TT.
But "cold" may be the key. 44 PSI cold is probably closer to 50 PSI after a mile or so of towing. So inflate your rear tires to 44 PSI cold and see how they feel when towing. "Cold" right now is about 50° F. ambient, and down to 40° on some mornings. I park my F-150 close to my air compressor, so I can adjust the PSI before moving the truck. Any movement will warm up the tires and raise the PSI in the tires.
I doubt the Michelin LTX MS/2 and AS/2 will feel different. I also doubt that there will be any difference in the "feel" of Goodyear and Michelin tires in the same size and specs.
