MG MGF Technical - Wheel size

What size alloys fit the F then. I haven't got a clue how it works. I can do tyres now, but alloys are new to me.

I think i have the fixing size undercontrol, well more so than othe parameters. 4 wholes is good and imke has an adaptor (not cheap however) that means you can fit 100PCS wheels (whatever that means). what has the MGF as standard, is it something silly like 97.6457839 just to be difficult (I realise why its an out of date size really, good old rover part bin)

But i haven't got a clue when it comes to width and offset, anybody able to give me an idea of the acceptable range for the F

Cheers in advance

As far as I know the wheels for the F will only fit Metro, Montego, Mistro and MGF witout some sort of converter (like available from MS). PCS (or is this PCD?) is the circle formed though the center of the fixing holes using the center of the hub as the center of the circle. Why they used this odd size on the 3Ms and the F I don't know but I suppost it makes your wheels less worth nicking.

I remember years ago thet some wheels came without holes and were drilled for the requirement by the supplier. Maybe my memory has gone and this was only for steel wheels. It was a very long time ago...

Depends on the wheel size. Mike Satur retails a variety of wheels and will have the information you need to source an alternative wheel- and better still, he sells a PCD adapter so 100 mm PCD wheels can be fitted to the 'F. :o)

Mistro, well it was the mean version...:-)

Matt,

I suppose you have seen this already on the midget thread.

Centre hole 56,7 mm
PCD 4 / 95,25 mm (3 3/4")
Size 6 x 15
Offset 28mm

The 16' rim data:
'official' from Rover EC approval paper:
size 7 x 16
offset 28mm

A try to explain the standard measures.
6 inches is the widht of the rim
15 inches the rim diameter

The offset is the difference between the middle of the rim width to the rims fixture plate (fixture to the axle).

The MGF standard offset is negative, so the right offset means -25mm.

If you add PCD adapters or distance washers you need to add their width (positive) to the 'true' rim offset.
Sample: 25 mm PCD adapters plus the standard offset (-25mm) results in an offset of zero mm.

The main reason in our country to meet always an offset near 25mm relates to EC rules which allow only total axle width differences of about 2 percent.
The offset has also strong influence on the following term of steering through curves and pulling back the steering wheel to the straight ahead line.

I never got the right english word for this effect :)
May be a speciallist here can best explain the meaning of the above site.
'negative steering roll radius ' ??

Clear ? :))

Now on the other hand the wheelhouse of the MGF restricts wheel width and offset.
If to small then the wheel scratches inside and if to wide then you need to bend the wheel house border lead inwards or make the wheelhouse wider.

Hope you can get my siimple engish :)
