I've towed fine with C and less. I've never lost a tire on a tow vehicle and I've towed some crazy loads with my antique tractor and engines.I was watching a video the other day that wasy saying how E rated tires were over rated when it comes to towing. They believed that the added weight and 10ply sidewalls were un necessary. But they didnt really site any info. Gave me a moment's pause where I considered an 8 ply next round of tires.
What makes you say the stock tires are flimsy? They seemed pretty good to me, just small.
I see the tire store charts online aren't exactly accurate - they list some low pressures for the tires like mine - mine say right on them max load 2750 max pressure 44 psi but those charts say 36 psi - what the heck is up with that? Mine have that in them now (because they were filled at about 45 or 50 degrees outside temp).
2750 per tire is more than my truck could ever dream of hauling.
I think when people start talking towing they are using maximum loads or something - not every trailer tops out at 6,000+ pounds.
A lot of how a tire will do depends on your SPEED, your care (inflations, sitting in the sun, age and so on) and more. Highways, 65 mph, moderate trailer loads.
The ply number is the "rating" - not that it has that many plies but a D or E will be a stiff tire, heavy.
The load rating letter is based on the old ply numbers, which is not a ply rating, not an actual number of plies. (Load range C is 6 ply rating - but these days they won't HAVE 6 plies, just the sidewall strength equivalent to 6 plies)
The letter ratings are rather antiquated anyway......... load INDEX is the ultimate guide these days. That's the real world "what will this tire carry" number.
