The specifications for Airstream wheels was fairly consistent from the 1960s through at least the 1990s. The standard wheel rim was typically:
- 15"x6"
- zero offset
- 6 lug pattern
- 5.5" spacing
- center bore measuring 4.245 inches
- rated at 2,600 pounds
The wheel is a comparatively common trailer applications. My local Good Year tire dealer stocked new rims having the correct specifications as did a horse trailer dealer and an agricultural trailer dealer. New rims from either of the three sources that I tried were less than $15.00 per wheel more for a brand new known quality wheel compared to a salvage yard wheels that could be in less than optimum condition. The center bore diameter can also pose problems as many otherwise compatible salvage yard wheels will have center bores that are too small and prove problematic when trying to mount the wheels/tires. The usual tire size recommended today is an ST or LT 225 75 R 15 in at least load range C or no more than load range D on a Vintage coach.
Something else that you might want to consider as you acquire the tools and supplies for your retrieval trip would be an air compresser. With Vintage Airstreams, it is not uncommon to find problems mounting a new wheel/tire combination with the tire inflated. When the Henschen axles fail or take a set, the arm will often not permit the hub/drum to swing low enough for the wheel/tire to clear the side of the coach for removal/reinstallation. This is something that varies from one trailer to the next, but it is a comparatively common issue with coaches that have original axles that are in need of replacement.
These are the specifications that I utilized when I purchased new steel wheels for my '64 Overlander in 1995 and again when I ordered new alloy wheels for it in 2009.
Good luck with your coach!
