I think you are overthinking a bit, all tires are over priced so pick the tire you like best and go for it. There is nothing wrong with "C" rated tires and I would steer clear of "E" rated tires unless you tow every day or do extreme off-roading. I would not be to concerened about the weight either unless you are racing priuses on your way to and from work. My two cents worth of advise.My head hurts from looking for new tires
So I find some i like but they (wildpeaks) weigh a f ton or the load rate (c) is too low, or the price is ridiculous. may just give up and go with what i have (bfg ko2 E) :/
I may be overthinking this whole thing. LOL
