Well call me the odd man out cause I've been running the GY Marathons (205x14s) since 1996 (that's 20+ years) for well over 100K miles total towing miles with only one flat and not a single blowout/tread separation on two different trailers. I did experiment for about an 18 mo period with the Kumho 857s, but had three of the four fail so back to the dreaded, but dependable China Bomb Marathons. Biggest thing I like is you can get them at almost any WM so availability is not an issue like with many of the other brands.
BTW I'm running my tires at within 100lbs of their max load capacity (actually closer to 50lbs on each tire) at all times so I have basically ZERO reserve capacity in my tires, but I do keep my speed religiously at 60mph and am very cautious about road hazards such as freeway potholes/curbing, etc. Over the years there have been time frames that one could ruin a set of tires from the freeway potholes in the Carolinas if one blindly drives down I-95 in the right hand lane. Several times I've opted for the Rt15/17 option just to avoid the terrible road conditions on I-95 in the Carolinas.
