Just ordered a set of 4 x 285/70/17 C for a grand total of $668.40 via Tire Rack with free shipping. That's $167.10 per tire!
The $192 list (before the additional discounting) 285/70 Ko2's are a "S" speed rated model with a 60psi max rating which sounds all good. Here's the problem--they weigh 58 pounds (which is roughly the same as the E rated 285) and they were discontinued this summer by BFG. By comparison, the current Q speed rated 285/70r17 weighs 51lbs...
I shopped these last week and passed on the cheaper, discontinued S version due to the weight, though I was tempted.
