I should have asked here first but...... I recently ordered a set of wide white-walls (2 1/2 inch) 235/75/15 from Diamond back Classics in South Carolina. Has anyone out there had experience with tires from these folks? It is February, 35 degrees below and I have nothing but time on my hands to sit and twitch until the tires get here. We have been trying to soda-blast our 56 Pontiac but the machine does not like to work very well once it gets down to twenty below. The tires are for my 57 Roadmaster.
