I?m due for new tires soon. Planning on Nitto Ridge Grapplers in 285/70r17. They come in load range C and E. I do tow my Jeep TJ a few times a year. I?ve got load range C now and it has done fine and they lasted about 50k miles. Would load range E be any better/last any longer? I know the ride would be somewhat stiffer due to the load range difference.
