6x127 Bolt Pattern

6x127 means 6 lugs evenly spaced on a 127 mm circle, 6x5 in inches. Adjacent lugs sit 63.5 mm (2.5 in) apart center to center. It is the factory pattern on Chevrolet Trailblazer, GMC Envoy and Buick Rainier.

Even a 0.7 mm mismatch (5x114.3 against 5x115) puts every lug off-center in its hole, so the lug seats carry the wheel on a sliver of contact and the wheel can loosen. The only accepted workaround for a small mismatch is wobble bolts on a hub-centric wheel, and only for the specific pair of patterns the bolts are made for. Everything else is a different pattern.

How to measure 6x127

With 6 holes every hole has one directly opposite it. Measure center to center across the circle and that number is the pitch circle diameter: 127 mm for 6x127. As a cross-check, two adjacent holes should be 63.5 mm apart (63.5 × 2 = 127, rounded).

You will also see 6x127 written as 6x5. Put your own measurement into the bolt pattern calculator to match it to the nearest standard pattern.

Where 6x127 is used

6x127 appears on 7 vehicles from 6 makes in this list: Chevrolet accounts for 2, GMC for 1 and Buick for 1. The earliest fitment here is the Chevrolet Trailblazer from 2002, and none of the listed models still use it, so this is a pattern you meet on used vehicles.

What else has to match

A matching bolt pattern is the first of four checks, not the last. The wheel's center bore has to match the hub, or be bridged with a hub-centric ring, so the hub carries the wheel instead of the studs. The offset decides whether the tire clears the suspension and stays inside the fender; run the numbers in the wheel offset calculator before buying. And the lug seats must match the wheel: conical, ball or flat seats are not interchangeable even when the thread is. None of those values are fixed by 6x127 itself, so check them per vehicle.

Frequently asked questions

What is 6x127 in inches?

6x127 is 6x5 in inches: 6 lugs on a 5 inch circle (127 mm divided by 25.4). It is the same pattern in different units, and 6x5 is how US wheel listings usually label it.

What cars have a 6x127 bolt pattern?

Chevrolet Trailblazer (2002-2009), GMC Envoy (2002-2009), Buick Rainier (2004-2007), Oldsmobile Bravada (2002-2004), Isuzu Ascender (2003-2008), Saab 9-7X (2005-2009), Chevrolet SSR (2003-2006). Always confirm on your own vehicle: the pattern can change between generations, trims and markets.

Is 6x127 the same as 6x130?

No. 6x130 is 3 mm larger in diameter. That is enough to seat every lug off-center, so the wheel is held by the lug hardware rather than by matching geometry and can work loose. Fit only wheels that are exactly 6x127, or hub-centric wheels with wobble bolts made for that specific mismatch.
