These are Jupiter 3 piece wheels. They are staggered, deep dish type style. The fronts are 17x9 and rears follow with 17x11. They come with tires, fronts containing 235 45 17 and rears with 275 40 17. Tires have tremendous amount of life left. I brought these wheels for my car but didn't fit. Offset is unknown. However I believe these wheels are for 1990-1996 Nissan 300zx. They can fit other cars too, just don't know which ones. Please pm if interested, Thanks
