If you're going to tow 7000lbs at highway speeds you should really have a LT tire. The lower pressure and weaker sidewalls in a passenger tire leads to excessive heat buildup and rubber break down. Overtime this ends in a blowout.
If you are just pulling this type of load locally and not very often maybe you can get by, but to rely on this tow vehicle on the highway requires better equipment. IMO
Not that LT tires won't be better, or overkill in the OP's case, but "Overtime this ends in a blowout" is 100% false, if the tires are used within their weight rating.
Unless you have more than the typical rvnet suppositions to support this, that is.
I'll offer that in 30 years now or about a million miles of daily driving mostly half tons for work, construction work, heavy towing, stuff that would necessitate about 2 dozen rvnet members getting coronary bypasses, OE P or XL rated tire do just fine.
Are they softer, yes. Do they wear out quicker, yes. Do they detonate due to being used at or even over their capacities? Nope.
