Have the Gen Altimax HP's on daughter's 01 Civic currently with 46k on them. Should easily get 50k+, rated then at 55k. Been satisfied, a have found them very hydroplane resistant even in heavy rain. That said, prime reason for purchase, I got an outstanding deal on them at the time, $50 visa rebate and a free shipping/no tax quote for DT to match/beat.
The Yoko ENV's have been well recieved here, and if not for a promo on another tire would have been my choice for a V6 Accord. Can't comment on the BFG. As mentioned, check Tire Rack for a comparison. IIRC, the ENV's have a good treadwear spec.
Since it's been mentioned, I got ~68k on a set of Yoko Avid Touring (now S) on the same vehicle, and was very satisfied with the overall performance of the tire.
