Tires for tow vehicle

You don't see too many "C" load range tires any more, maybe in 15 inch. Most you'll see now are 8 and 10 ply. If your weighing out pros and cons for the guy that tows only a few times a year but needs tires and wants to be as safe as possible..... Cons: Only 1 I can think of and that's more expensive. The Pro's: stiffer side wall make for better towing, stronger sidewall makes for less chance of a rock or any debris puncturing the sidewall, longer life of the tire. I've done this years ago with my 99 Tahoe, towing a tongue heavy car trailer..... One trip down the highway with "P" tires then switched to LT and what a difference and little to NO ride quality sacrifice.
