Theres good and bad in all things i guess , i've had good luck so far with the Carlisles , my trailers are always working when they go out of the yard , genrealy carrying a fair amount of weight , probably more then most , i've tryed others over the years but they wear realy well over the others i find , the real test for me with them is on our damdem axle trailers which drag lots when your turning with weight , for the weight i like their harder compond . As for the Hercules Tires , i put my first pair of LT's on the wifes jeep liberty a year ago and i would have to say for the money i am liking them , they seem to be standing up to the wear .
