Home - Discount Tire Direct
Got them for ~$130 a corner with free shipping.
Can I advise against the Nittos though? I love the tire for its abilities and look, but they are SO stiff. It wasn't so bad in the summer but since winter has hit they have really stiffened up and made the ride almost unbearable. They also make a "thump" sound over bumps. I wish I had chosen something else.
What load rating did you get? I have p-rated TG's cuz I do more on road driving than anything and mine ride really nice even when it's really cold!
