I’ve been in Death Valley on really rocky, rutted, cliffy, and hilly terrain over 50 miles from the nearest gas station. On situations like that, you are glad you are on e rated tires.
On a hot day in this remote terrain you are also glad your cooling system, battery, brakes, and fluids are in tip top shape.
And yet I still overheated the brakes in this darn death valley trip because of the rocky descent was too steep and I was on the wrong road. I had to turn around and go back uphill. I should have used DAC but I thought I had it on my own.
So, my point is that you prepare for the worst and hope for the best when you go far off the pavement.
Now if you don’t find yourself in these type of situations, then don’t go overboard with the preventive maintenance like the cooling system or the battery. Nor worry about stronger sidewalls with e rated tires. A tow truck or the auto zone are within easy reach.
My point of view is different because of those situations that I’ve been in and probably find myself in when exploring in the near future.
