bolt patern????? plsss help

[xzyclone]

hey

well im new here, and i have a quick question
im thinking about buying new rims and i was wondering what bolt patern my car has its a 01 grand am 2.4l

diffrent ppl told me diffrent specs for example i heard that the bolt patern on my car is 5 bolt 115 bolt patern and 5 x 4 1*2 inch bolt patern. Now what does that mean is the 115 thing same as 4 1*2 inches or does it go together i just dont get it.

now the specs for the rims that i want to buy are

5 17" Niche "Runner" Rims (yes 5) (5 bolt pattern) They were fitted for a 97 Pontiac Grand Am GT, but should fit Grand Prix, Alero, Bretta and similar GM Class cars


I also e-mailed a guy about a diffrent set of rims and this is what he told me


Hello,

The pattern is bolt pattern = 5 x 100 and 5 x 4.5. Which means it
would fit
your 5 x 4.5



So if you guys could pls clear this up for me its realy confusing with all the bolt paterns i just dont want to buy rims that would not fit my car


thanx a lot

i don't think the rims you are looking at will fit. Because the 97 GAGT has a different bolt pattern that the 99+ GA's . You said the rims were made to fit a 97 GAGT, they won't fit on a 2001 GA. bolt patterns are different. i think in the FAQ section of the forum it explains the bolt patterns for our cars.

Your bolt pattern is 5x115, and nothing more. Yes, 5x4.5 is close, but it does not allow the lugnut to properly seat on the rim. This can potentially damage the rim, and the stud, as well as the chance of a wheel coming off altogether.

Do it right, don't half-ass it ... get 5x115.

A little more clarification seems to be in order.

When you see a measurement like 5x100, or 5x115, or 4x100, the measurement is in millimetres, a metric measurement.

In 1 inch, there are 25.4mm. So 100mm (the 100 in 5x100) in inches is 3.937, or 3.94 inches, or 3 and 15/16 inches - not quite 4 inches. 115mm would translate into 4.528, or 4.53 inches, or 4 and 17/32 inches - a bit more than 4.5 inches.

While it can be possible to fit a 5x4.5 pattern (which FYI, is 5x114.3) on a 5x115 car, or a 5x4 pattern on a 5x100 pattern, I would never recommend that. It will ALWAYS be preferable to buy a wheel that exactly matches your particular vehicle's bolt pattern.

While these seems like small amounts to be out by, consider that the majority of a car's parts are manufactured to thousandths of an inch, not 16ths or 32nds. In comparison, these are significant differences.

Oh, I should mention that some manufacturers make certain models with two sets of bolt patterns drilled into the face - the rims you mentioned in your post are likely drilled with both patterns.

I would still recommend against them, though.

Very well said Jason!!!

BTW, where the heck have you been?
