I recently returned from a hot rod show/swap meet and while there I picked up a really cool plastic template for measuring 5-stud wheels. I know there's been discussion on the forums about what bolt pattern a member's trailer wheel has and several members have assisted by giving methods for measuring (
Tires n Rims). But this template is so easy to use. I traced the plastic template, scanned it in, placed the numbers, created the PDF and placed it in the document center.
You'll find it here:
Manuals - Axles and Running Gear
To use it, just print it out at 100%, poke holes through the four circles at the top 4 3/4,
4 1/2, 5 1/2, 5 and the larger center circle. Place one of the studs through one of those holes and start rotating to see what circles line up. You may have to try all four holes to find out precisely what pattern the wheel has. Slick.
I'm on the hunt for a 4-Stud template
