I heard Firestone might have a set. Give them a call.

The best tire deals can be found at dealerships and some tire shops.
Some people are not satisfied with the tire and wheel combination that
comes with their new trucks. These perfectly good tires and wheels often
end up in the dealer parts department as "takeoffs."

You can often upgrade both your tires and rims, for less than the price
of tires alone. And the takeoffs are already mounted and balanced. On
top of that, you can sell your used rims and maybe your used tires.
