So I am looking to replace my current rims and I cant seem to find the right info. The websites say my rim bolt pattern is one size but every place I look doesn't sell that size bolt pattern. So I am wondering what is the correct bolt pattern size for my 99 Pontiac Grand Am SE?

All trims levels were 5X115 with a center bore of 70.3 mm. Original rims could be 15” 16” or 17”, but I doubt they are 17”.

Agreed, highly doubt 17s. Likely 15s

Reading.  Were/are 15s the original/standard when the GA rolled off the floor?  I have recently bought a 99 GA GT.  It has low profile, which I can't stand.  Live in a rural area and we get enough snow that I don't want to be in an azz dragger and get stuck.  Help!  Searching to replace wheels and tires and get back to orig/stock.

If I'm  not mistaken the original tire..wheel size would be on a placard located in the drivers side door jam....Also one of the three letter codes on the service parts ID label.....also would indicate the tire wheel size it was originally equipped with......

Original bolt pattern is 5x115 but you can also get 5x114.3 as it's close enough to fit.  Normal rims were 15" (2.4L SE) or 16" (V6 SE and GT); they never came with 17" from the factory and 18" is the largest you can safely go without worrying about rubbing.  I had 18" on my old GAGT and loved them but the ride was definitely a little smoother on the stock 16" rims.
