No doubt if I was replacing tires on a “C” or Axis, I’d spend a little more to get the higher load rating as long as it didn’t affect fuel economy — and I don’t expect it should.
My point was that upgrading tires doesn’t upgrade the overall load rating, which I believe you agree with. It just reduces risk of blowouts, so improves safety some. We shouldn’t overlook axles and other components though because their failure can be more dangerous than a blown tire. A cousin rolled a Jeep when he lost a rear axle with wheel. My father’s boss broke a rear axle on a Ford F-150, and fortunately came to a stop minus one wheel. And a high school friend broke a rear leaf spring, which led to a minor accident, but could have easily been serious if not for great luck. By comparison most blown tires don’t cause an accident at all.
So I agree tire failures are more common, but consequences aren’t usually as bad.
