I have a problem with one of my bikes that's killed two new (but deformed) tyres by rolling them off the rim and breaking their beads.
I'm trying to isolate the problem to either the deformed tyre or the rim so am looking for an otherwise-dead tyre to trial-fit to see if it suffers the same fate.
Since I suspect it might be the tyre's deformation that's causing the issue the "test tyre" must be straight, but I'm not bothered if it's got no tread left / is cosmetically nasty etc. All I want it for is to ride 5-10 miles to see if it stays on the rim, before either replacing it with a better one or looking at replacement rim options depending on the outcome.
