HRE Wheels
Hello, I have a set of HRE wheels from a friend who had a C5. They are about 10 years old, mint condition. Wheels stamped 5T18P588510 and 5T19P568520. Trying to determine bolt pattern and offset. Any help would greatly appreciated. Can't find much on the web. Thanks

If they were mounted on a C5, bolt pattern is probably 5x120.65. To determine the offset, we will need to know wheel widths, first. Do you know how to measure widths, correctly?
Also need to know the wheel backspacing.

That is an HRE 547 which is an awesome 3 piece wheel. They are super light and super strong. HRE can refurbish them for you if needed. Wheels of that vintage, HRE often engraved the full specs on the barrel.

The below explains how to measure backspacing but you must also know how to correctly measure the wheel width, to figure the wheel offset.

To accurately measure wheel width, measure from the inside edge of one bead seat to the inside edge of the other bead seat, typically in inches.
