Tires are doing well. The only thing is that the 40" tire from Pro Comp is no longer available, Cooper decided not to make them anymore. As as Super Swamper goes, what tire were you thinking? I know they are still making some tires, just not the LTB's, those are made in China if I am not mistaken. The other tires are about 90-120 days out. I really like the IROK's, might even get some myself. The Pro Comps are great, I just like the look and the grab of the IROK's.
