This seems important enough that I'm going to cross-post it to the "Tires" forum as well. We'll have to wait and see if it affects any versions used on Jeeps.
"NEW YORK (AP) – Goodyear is recalling six versions of its Wrangler Silent Armor tires over concerns that the tread could separate from the tire and cause accidents.
Goodyear Tire & Rubber Co. said Saturday that the separation could happen under what it called "severe usage conditions." Goodyear says the separated tread could strike the car and damage it or cause a tire failure.
The tires are designed for trucks, vans and SUVs. Goodyear says it will notify owners and replace the tires for free. The recall will start by March 22.
