Re: 2013 Jeep Grand Cherokee Laredo
No wheel spacers, the Rubis have a little more "poke" built into them. I'll try to get you a pic of that later.
And regarding the tire size, the picture doesn't really do it justice. It's a huge improvement over the stock 245/70/17's. I've had them on there since March and I still get random people in parking lots coming up to talk about the tires/wheels. Wish I'd done a long time ago.
