Fourth generation Camaros came in RS and, the more powerful, Z-28 trim lines. Some years also offered convertible versions of both. The RS models came with only one available rim, while Z-28s had options. Most of the basic specifications of all these tires were the same. Because rims are often one of the main aftermarket accessories car owners buy for their cars, it is important to know the specifications when choosing new rims.
Several rims sizes were available on fourth generation Camaros. Before 1996, all Camaro rims had a 16-inch diameter and an 8-inch width. From 1996 until 2002, Z-28 models had optional 17-by-9-inch rims. The spare was a 14-by-4-inch rim. Some of the rims were only the basic, steel wheel with a plastic hubcap, while others were alloy or aluminum, five- or 10-spoke rims.
The bolt pattern refers to the number of bolts and the diameter is an imaginary circle that is formed by the centers of the bolts. For all Camaros of this generation, there are five lugs and the diameter is 4.75 inches. When measuring a five-bolt pattern, it is best to use a bolt pattern gauge. The bore, or center hole, of Camaro rims is 2.76 inches, or 70.3 mm. The bolt is 120.7 mm long and and the lug 12 mm by 1.5 mm, meaning the inner-diameter of the lug is 12 mm and the thread spacing is 1.5 mm.
Backspacing refers to the distance from the inner edge of the rim to the mounting surface--the surface that touches the brake pad. On all Camaros, this distance is 6.875 inches. The offset refers to the distance from the center of the rim's width to the mounting surface. On a 16-by-8-inch rim, the center is 4 inches. Fourth generation Camaros have a high offset of +35 or more. This distance varies, depending on the specific rim. It is important to know the backspacing and offset to know how close the rim is to the suspension.
