TR didn't have the extended load rating chart, but I was able to calculate it
Load index lbs kgs
111 2403 1090
112 2469 1120
113 2535 1150
114 2602 1180
115 2668 1210
116 2734 1240
117 2800 1270
118 2866 1300
so you are looking at 2602 lbs per tire at about 35 mph. Sitting still, or rotating slowly would be significantly more (which is where you would care, right?). The LT tires are like 3415. You are comparing it to a Comercial rated tire.
C = If a Euro-metric sized tire ends with a "C," it signifies the tire is a "Commercial" tire intended to be used on vans or delivery trucks that are capable of carrying heavy loads. In addition to being branded with the "C" in their size, these tires are also branded with their appropriate Service Description and "Load Range" (Load Range B, Load Range C or Load Range D).
I didn't see what the specific load range was on your tire
onward...
LT = If a tire size begins with "LT," it signifies the tire is a "Light Truck-metric" size that was designed to be used on vehicles that are capable of carrying heavy cargo or towing large trailers. This includes medium and heavy-duty (typically 3/4- and 1-ton load capacity) pickup trucks, sport utility vehicles and full-size vans. Tires branded with the "LT" designation are the "little brothers" of 18-wheel tractor-trailer tires and are designed to provide substantial reserve capacity to accept the additional stresses of carrying heavy cargo.
So I would assume that the LT is similar to C. With a 4200 lb truck, and 400 more in stuff you only have 4600 lbs. That means you could support the entire weight of the vehicle on two 114 tires at 35mph (5204lbs to be exact). Do you really think you need the C rating? I don't know what you intend on doing with your Pathy so I presented as much info as I could.
