I visited my son in Salt Lake City a few weeks ago and insisted that we go to the Landcruiser Museum. Great place and free to visit. Full of beautiful rigs. Recommend if anyone is in SLC.
I put 7.5r16 KM3 on my 40. Used Vision 40sm-6683 steel wheels. $165 for 5 wheels delivered to my house. Scuffed and painted gray. Turned out great. 7 inch wide wheel, 3.5 inch backspace.
