Can wheels with the 5114 bolt pattern be used on 2004 impala?
No. A 2004 Chevrolet Impala uses a 5x4.75" (5x120.65mm) bolt pattern. A 5114 bolt pattern doesn't exist as a standard automotive wheel pattern. There's likely a misunderstanding or misinterpretation of the bolt pattern designation. You need to double-check the correct bolt pattern for the wheels you're considering.
