What size wheels came stock on the Xterra?

The Xterra over the years has been available with 15", 16" and 17" wheels. All are 7" wide (except for the 17" size, which is 8" wide). The bolt pattern is 6 x 5.5" with a thread of 12mm x 1.25.

To accommodate larger wheels and tires on the 2002 and up model years, Nissan has switched mudflap design.
