I bought a set of 255/85-16's about 1 1/2 yrs ago online from DiscountTire, and my date codes were 2yrs old...
Also, after having run these on my 1st Gen Tundie for half the winter, sad to say, I'm pretty disappointed with them on-road in the snow and slush...Even with 400lbs of sand in the back, I was easily spinning the rears from dead stops, even being easy on the skinny pedal....Also, had a couple close calls of almost sliding off the road on slight curves in 3" of snow, doing 35-45 MPH...(PSI wasn't even very high @ 30 front/27 rear)..
Unfortunately, I didnt get to play off-road in the snow with them...
These are a far cry from the original Gateway Buckshots the Bighorns, and the Maxxis Buckshots, are modelled after...I had a set of those in 33x9.5-15s that handled WAY better on my 99 Taco...a MUCH lighter truck, and even with more sidewall to flex...
I dont think i would have liked the weight gain or the look, but I'm thinking 285 or 305s would have been better for the '00 Tundie...
