Approved wheel widths run from 8.5 to 10 inches, and new tread depth is listed at 18.9/32 inch. Open tread voids help clear mud and dirt; deep center sipes support wet traction.

Maximum single-tire load is 3,640 lb at 80 psi. Match the tire size, wheel dimensions, load and speed requirements to your vehicle, then have a qualified installer check steering and suspension clearance.
