Gents, from my experience, the difference between "D" rated and "E" rated is often only one letter in the alphabet... If you upsize, a larger D rated tire may actually have more load capacity than a standard size E rated tire. Just saying...
Case in point, my STT's in 285/75R16 are D rated, while the same size Maxx is E rated. They're on the same carcass according to Cooper, and they both have a 3750lb rated max load. So what's the difference? One letter in the alphabet. They're both WELL above the 3042lb E rating of a normal 245 or 235/85 tire.
Not sure why this is, but ALL of the Maxx sizes are E rated, and my guess is that this is for marketability to guys just like the poster above who has to have an E rated tire. I think the rating of D vs. E may depend more on how they felt like certifying them at the time than much else. We'll just have to wait and see what comes out.
