These are forged Centerlines, 17 x 8 with 5 inch backspace. 1/2 inch spacers and extra long high strength lugs brings them out for a wider track. Tires are 245 x 45 x 17 Kumho 4X's. If they had been available back when I was wheel shopping I probably would have gotten the Year One Rally reproductions in 17 x 9 with 4 1/2 inch backspace.
