Hey guys, the stock size is actually a 205/55/16. You can also run a 215/55/16 (a teeny bit taller) and the most popular, 225/50/16. The last size gives you the most useable tread on the ground, and is back to the stock sidewall height. I work as a tire tech at America's Tire Co., and can look up any other tire info you guys need.

And tire size (X/Y/RZ) works like this:


X= Bead to bead length in millimeters
Y= The percentage of X left over for sidewall height
R= Radial Tire construction
Z= Rim size, in inches (16 inches for stock wheels)
