Raleigh inner tubes - (eBay) - junk?

[DxMachina]

Hi all

I have a bike with a 26 x 1 3/8 wheel that needs a puncture repair.
I removed the nail and bought 4 Raleigh inner tubes via eBay, and a decent polypropylene rim tape

I then changed the inner tube, in accordance with instructions,inflated it and it split along the inner edge.

I removed it, re-positioned the rim tape, put another tube in, same thing happened

To cut down repetition: I have now put no fewer than 5 inner tubes on this wheel and every single one punctured on the inside edge before it was even fully inflated. For the last three I even fully lined the rim with duck tape as well as the rim tape.

I''m not a great bike mechanic but I know how to change a tube!!! Why is this happening to me???? Did Raleigh stop making inner tubes a long time ago and am I buying old degraded stock? Is there some incantation that must be made or a sacrifice required?

Or is it just not my week?

Do they split if you inflate them off the wheel, like a balloon? If they don't there's something wrong with the wheel or the tyre - a burr, a little bit of the nail still in the tyre or something like that.

Most of my inner tubes are eBay Raleigh specials. Not had any issues with them. Are the definitely the right size and diameter? If it's too small diameter they have a habit of splitting.
