I ran a set of E rated Atturos on one of my fleet trucks (loaded f-150 4x4) for a week then got my money back. I was thoroughly unimpressed. Even with the E rating, the sidewalls were only 3 ply and handling was a ridiculous challenge, even dangerous at highway speeds.
I ended up spending 2x the money on a set of Goodyear Wrangler Silent Armor Kevlar belted tires and have gone with them ever since. Better sidewall protection, they handle the weight, long wearing and have all but eliminated puncture issues.
I manage a fleet 20 vehicles for an engineering/survey company. Half ton truck constantly running with 1500+ pounds of tools and equipment running as much as 20,000 miles per year each.
What's the difference between a 4x4 and a work truck?
There's some places a 4x4 can't go.
