Pontiac Grand Am Wheels and Rims

Pontiac Grand Am Aftermarket Wheel Fitment

The Pontiac Grand Am is Pontiac's compact N-body car, with a nameplate that ran in various forms from 1973 through 2005 when it was replaced by the G6. Element Wheels measures fitment on the 1992-2005 Grand Am, which covers two N-body generations and includes the SE, GT, and GT1 trims across both sedan and coupe body styles. Important: the bolt pattern shifts in 1999. The 1992-1998 Grand Am uses 5x100 with a 57.1mm hub bore. The 1999-2005 Grand Am uses 5x115 with a 70.3mm hub bore. The two are not interchangeable.

Find Your Pontiac Grand Am Generation

Pick the year range that matches your Grand Am. The 1992-1998 Grand Am is the fourth generation N-body car and uses 5x100. The 1999-2005 Grand Am is the fifth and final generation N-body car and uses 5x115. The two bolt patterns are different (more on this below), so the row you pick determines which wheels fit your car. The earlier 1973-1991 Grand Am nameplates ran on different GM platforms and are not part of this catalog.

The Pontiac Grand Am Bolt Pattern Shift

The Grand Am went through a bolt pattern change in 1999. The 1992-1998 fourth gen Grand Am uses 5x100 with a 57.1mm hub bore. That hub spec was shared across GM's smaller-car N-body and J-body cars of the era (Pontiac Sunfire, Chevrolet Cavalier of the same range, and the Oldsmobile Cutlass Calais sibling). The 1999-2005 fifth gen Grand Am moved to 5x115 with a 70.3mm hub bore. That hub spec is the same one GM put on the W-body Grand Prix the Grand Am was sold alongside. Both Grand Am rows use an M12x1.5 lug thread with 5 lugs.

Two important distinctions to confirm before ordering wheels. First, a 1992-1998 Grand Am wheel will not fit a 1999-2005 Grand Am, and vice versa. The two bolt patterns are not interchangeable. Second, 5x115 and 5x114.3 are NOT the same bolt pattern. The two patterns sit roughly 0.7mm apart on the hub circle, small enough that the studs will start through a 5x114.3 lug hole on a 5x115 hub, but the seating will be off-center and the studs will be stressed unevenly. Over miles, that mismatch leads to wheel wobble and, in worse cases, lug failure. The 5x4.5 imperial nickname (114.3mm equals 4.5 inch) refers only to 5x114.3. The 1999-2005 Grand Am is 5x115 specifically. Compare across the rest of the Pontiac lineup at our Pontiac wheels and rims hub.

Why Grand Am Fitment Is Stable Within Each Generation

Within each generation, the Grand Am keeps the same hub geometry across every trim and body style. On the 1992-1998 fourth gen, the SE coupe and sedan and the GT coupe and sedan all share the same 5x100 / 57.1mm hub. On the 1999-2005 fifth gen, the SE, GT, and GT1 trims all share the same 5x115 / 70.3mm hub. Pontiac did not pair the GT or the GT1 trim with a different hub or brake spec. A wheel that fits a base 2002 Grand Am SE sedan also fits a 2002 Grand Am GT coupe of the same model year.

The diameter window we measure on the Grand Am differs between generations. The 1992-1998 row runs 14 to 18 inch, reflecting the smaller fourth gen factory wheels. The 1999-2005 row runs 15 to 20 inch, reflecting the larger fifth gen wheels and the rim-up trend that hit GM mid-size cars in the early 2000s. 16 to 17 inch is the most common fourth gen Grand Am aftermarket choice. 17 to 18 inch is the most common fifth gen Grand Am aftermarket choice. We measure each generation directly so the catalog reflects what actually clears the fender and the brake.

Every wheel we recommend is backed by our Fitment Guarantee. If a wheel does not fit, we pick up the wheels and refund 100 percent. No risk to you.

How We Confirm Fitment on Pontiac Grand Am Wheels

Element Wheels measures fitment on the Grand Am directly, across both the fourth gen and the fifth gen, sedan and coupe, base SE, GT, and GT1 trims. For the Grand Am that means hub bore confirmation (57.1mm on the fourth gen, 70.3mm on the fifth gen), clearance from the wheel to the fender on a stock-height car, gap between the back of the wheel and the front strut, brake caliper height at the standard N-body spec, lug seat depth, and lug thread confirmation at M12x1.5. At our fitment facility in Chandler, Arizona, the Element Wheels team measures directly on the physical platforms we support. We don't pull specs from manufacturer sheets the way most retailers do.
