My Tundra came factory with E rated tires. I love my tires. My wheels are rated to handle the 80 PSI max pressure of my E rated tires, though I have never gotten above 65 PSI. The E rated tires are WAY overkill for my 7200 lbs GVWR (I think that's right...) though. When it is time to replace them, I wil likely look for a D range tire. I prefer overkill with my tires though. I find that modern pickups ride WAY more comfortable than my old pickup ever rode. Even with E rated tires, my Tundra rides way better than my 95 F-150 ever did.
