This question is mostly for you really old guys on here.
I bought an old piece of farm equipment (hay wagon) with one of the
tires being an old 8.00 x 15 tire. (the other 3 tires were modern
tires). Anyhow, I cant imagine how old this 8.00 x 15 tires is, but I
know it probably goes back to the 50's or 60's. (I'm not exactly
young myself). I recall in the 70's they were using an alphabetic
character at the beginning, such as G78 15. Then in the 80's they
began using something with a P at the beginning such as P225 75 R15
(and those were steel belted radials).
Amyhow, this old 8.00 x 15 tire still holds air, and is not badly
cracked, and still has half it's tread. But that tire was wobbling
and I had a friend drive behind it and he said the rim must be bent.
I jacked up that wheel, and put a carpenter square on the ground and
spun the tire. I bet it deflected 1" on one side of the tire. In
other words one side of the tire touched the square and the other side
there was a 1" gap, or possibly even 1 - 1/4". Then I only watched
the rim, and saw that it was the same all the way around.
Therefore the problem is the tire itself. I have seen the modern
steel belted radials get belt separation and a big bubble in the tread
area, and those old shortened letter ones such as H78 x 15 also got
bubbles, both on the tread surface and the sidewalls. But I have
never seen a whole tire warp to the side where the sidewall is shifted
an inch or more, so the sidewall on part of the tire is an inch or
more closer to myself than the other part of the tire.
Was this a common problem on those really old tires? Is there a name
for this defect?
Thanks

The tire is a bias ply that ran in the 50s to early 60s. Touch the
side on both side of the bulge and then the bulge. Feel the same?
Most likely sidewall separation between the plies as in a bubble or
maybe the cords have weakening and streatched. This was not a big
problem back then, but these tires were supposed be worn out 30 -40
yrs ago.
