WHEELS

[Willie]

Lo, I am in contact with a chap called
Reinhard who wanted to know which Minors
used the 3inch and 3 1/2 inch rims. Since i
have always known Minor wheels as 4J and
4 1/2J I told him they were not standard.
Now that I have measured my wheels I find that they ARE 4 inches across edge to edge
but only 3 inches inner wall to inner wall.
I always understood that the 'J' measurement
is from INNER wall to INNER wall of the rim
(i.e. where the tyre sidewalls touch). this
would make the MInor wheels 3J and 3 1/2J
Am I wrong???

Iwould agree with you that the measurement is across the inner edges of the rim.
3" or 3 1/2 " would seem right for a Morry as the 59 mini came on 3 1/2J as standard , and 4 1/2J was only used on Cooper S.

I have always understood that 4 1/2 inch wheels were fitted to late commercials.

Correct. The 4 1/2 inch wheels were only fitted to the 8 cwt vans. from 1968.earlier van wheels are NOT wider than the
cars. the 4 1/2 inch measurement is across
the rim edge to edge. I believe this is NOT
the correct"J" measurement.

From what I understand, saloons had 3J, 4cwt vans 3.5J, 6cwt vans 4J and 8cwt vans 4.5J (sought after by many!)
The measurement is from inside to inside.

Ummm, This gets more confusing, it seems to me that the wheels are wrongly called 4 1/2J
(late vans 1968 onwards....8 hundredweight)
when the 4 1/2 measurement is outer edge to
outer edge. This is not a correct "J" measurement. I also think that van wheels are the same as the cars until the advent of
the 8cwt van?? The 1098cc cars and vans had 5-20X14 tyres but I don't think the wheels
were any wider.
