Thanks, They are 15x7 with 4 3/8" of backspace, the wheel says 8 offset. There are other ones like this that say '10' offset, not sure what the backspace is on those. I measured these and came up with the 4 3/8" so it may be plus or minus a few 8ths. They weigh around 16 pounds each, but are a flat seat so they take a special lug nut. You can't use the tapered seat lug nuts that our factory wheels use. I'm still looking for center caps and a 5th wheel for my spare. The Toyota wheel part number (as far as I can tell) is 69305. The lug nuts are 611-117 M12-1.5 x21mm and can be found on rockauto for a few dollars each.
