Bolt Patterns

Hey guys do you know what the bolt pattern is to a 1992 Firebird 3.1? I'm looking to put on the magnum 500 wheels on it but I need to know what bolt pattern I have before I can purchase them. Also in 245/50-17, what does the 50 and the 17 mean? Thank you guys

Re: Bolt Patterns

This should be in the suspension forum.....

The wheel bolt pattern of all third gens is 5x4.75"

The "50" is the aspect ratio, that is a measurement of 50% of the tread width is the sidewall hight. 17 is the wheel diameter in inches.
