Gm 5 Lug Bolt Pattern

Answer 3

If you go to speedwaymotors.com they have the following explanation and picture concerning measuring non-metric bolt patterns. It goes like this: On the back side of a wheel measure dead center of a lug hole. Skip the next hole and measure the furthest outside edge of the second hole in line. That will be be the bolt center. Sorry to say the Trans Am's 5 lug pattern is metric and will not the other two hubs.

Answer 4

Measure them.

Instead of bolt circle diameter, you can just measure center to center between two non-adjactent lugs. Repeat the measurement for all five lugs so that you can average your answer.

For offset aka back spacing, take the wheel off, measure from the surface that is clamped by the lug nuts to the spindle, to the inside edge of the wheel (not tire). You can put a straight edge accross the wheel (rim) and measure to the mounting surface from the straight edge.

Answer 5

i think chev wheel bolt pattern up to about 1990 was 5 bolt at 4 3/4 inch pcd. after that they went 5 bolt 120mm pcd. if the wheels fall either side of that date, they wont interchange as 120mmpcd is slightly bigger and wont fit. another thing to think about is the offset (or the amount of dish the wheels have) this can affect how they sit on the hubs an if they'll fit also. ask your local tyre/wheel shop, chev dealer or wrecker about it

silverado trucks have a 6 bolt 5 inch pcd it think, so therefore they wont fit either.
