so I guess I will be running 38s to start. I have a buddy that bought a set of 38s and less than 100 miles later he blew up the truck and sold it for parts and kept the tires and rims. the tires are mickey thompson baja mtz 38 16.50 15 and the rims amercian racing rims for $1000. he paid $2100 with mount and balence.
