Stainz Traction Tyre

Semi-Retired; more time for trains.
I fitted a new traction tyre to one of my Stainz the other week, the first odd thing is that they come flat like a washer. I tried it with the inner circle on the inside of the wheel, and it came loose, and with the inside on the outside of the wheel, both ways it fits snug, but when I run it it sort of “puckers” up leaving a large piece of tyre not seated. What am I doing wrong.

Is it one of those I sent you Jim? It came out of a sealed packet, but with no part numbers on the bag. I've not had need to fit any yet. When I have time I'll see if I have another lot to check if they are the same size.

Hi Jimmy,

Not had any problems quite as you describe. (Puckering.) However there have been a few times when the tyre did not stretch evenly, it seemed to be a malleability consistence issue, which led to areas of reduced thickness. Obviously the thin areas had stretched more than the rest, meaning the tyre was not as tight as it should be. Potentially this could be the cause of puckering.
I’ve also noticed that some of the tyres currently on offer are more rigid than the older ones.

I had one bagful arrive that were dark yellow and stiff as a board. Luckily a quick dunk in near boiling water prior to fitting, followed by fast cooling in cold water helped immensely. They expanded and shrunk as I had hoped.

So far, I’ve not had any problems with them whilst running. (Obviously I had to remove the wheel set to do this.)

Hope this helps,

Paul.

I have had them where I get a 'bump', which seems to be where they were joined, or a moulding artefact?? :think:

Mostly, it seems they (especially if in LGB packaging) they are old, less supple, even to the point of being brittle.

You can normally ease them into a better shape with a small flat-bladed screwdriver..
If they are puckering, in use: It suggests to me, the wheel was perhaps greasy/oily? - I would de-grease both the wheel rim and the traction tyre, and try again.

Perhaps you got the larger 46.5 MM wheel tire. The tire is much smaller than the wheel and is difficult to install. If easy to install then it is the wrong (read too big) tire for the stainz.
