these were called porta-walls when i bought my 1st set for a 49 oldsmobile. there was no glue involved; they were captured by the outer bead of the tire, the porta-wall being the same diameter as the tire, with part of it descending between the rim and tire. it was necessary to beat them into place with a rubber hammer whilst re-inflating.
no glue involved. the whitewall was the same inside diameter as the tire and was forced over the rim of a deflated but not dismounted tire. when re-inflated (and beaten with a rubber mallet to make it behave while doing so) it was pinched between the tire and the wheel.

ReplyDeleteI'll wager they were metal, and held in place by the hubcap.
ReplyDeleteI have these on my 1935 DeSoto - they've been on the car for at least 50 years.
