The above photos are of an original NOS set of Uniroyal Steel Belted Radials. The below photo is of an original Goodyear Polysteel Radial. Production of the Uniroyal tire was halted in late 1985 and they have never been reproduced. All 1981 Z28 Camaros had either the Goodyear Polysteel Radials or the Uniroyal Steel Belted radials. The Goodyear Polysteel Radials ARE being reproduced and can be purchased for about $275/each. The Goodyear Polysteel reproductions are accurate, but there are several ways to distinguish an original from a reproduction, the most obvious of which is the date code. Early in my research, some people suggested that the tire utilized was specific to the production plant and that the Norwood plant installed Uniroyals and the Van Nuys plant installed Goodyear. However, continued research has confirmed that both tires were utilized at each of the plants, with the specific tire utilized being based on timing and availability.

The photo directly above is of the date code on an original Goodyear Polysteel Radial. The last 3 or 4 numbers determine when the tire was made.  For example, the above date code MKUU 1231, MK means they were made at he the goodyear plant in Union City, Tennessee. The UU is the size of the tire. The "123" means 123rd day. The last digit, in this case a "1", is the year of 1981. The same system applies to the Uniroyal tires. The date code photo which is directly below the Uniroyal tires above reads APUU DH 181. The "AP" means they were made at the Uniroyal plant in Ardmore, Oklahoma. The "UU" is the tire size. The "18" means 18th day. The final digit "1" means 1981.
