Pretty sure that the 285 is D-rated; Don't know why, wish I did.
Go here--http://www.michelinman.com:80/tires/light-truck/ltx-at2/#sizes-and-specifications
Then click tire specs and pick a size to view specs.
PS--I DO really like my E-rated ltx/at2. Had em for 10k miles on highway, in snow and rain, and on gravel roads. Handle great, wearing well. Took only 2 wheel weights on the stock forged aluminum rims to balance the whole set of tires and wheels. I think I'll see 35k miles, based on wear right now. Definitely buy em again, unless something else shows up better.
