Tire sizes

[battalla1]

I am getting new tires tomorrow and the dealership says it’s supposed to have diff sizes on the front and back does anyone know if this is correct and if so how do you rotate tires. It’s a 2015 3.8
ultimate rear wheel drive. Thanks

There is a plate/sticker on your driver door jamb that outlines the required tire sizes and pressures. To answer the rotation question simply.. you dont. Staggered fitments are very common now

The 3.8 doesn't have a staggered wheels/tires. Unless you put aftermarket wheels or for V8 5.0
