Not everyone drives a fullsize truck and needs load range E. On a lighter vehicles like a Jeep or 4-runner or other midsize vehicles, a load range E can become unbearably rough riding. But don't worry, tire companies tend to think like you and assume everyone wants a load range E. So you shouldn't have to worry about wasting 5 seconds of your life looking past a single load range C tire while browsing the 1000 load range E options you have available. On the other hand, those of us looking for load range C tires, will be scouring the internet high and low for months, hoping that someday somebody will build a decent load range C tires that fits our rig.
