Would it matter having one rim 0.5" wider on the rear?
Strange one.... I've got some new end of the line wheels. However one is 8J instead of 7.5J like the rest.
Would it matter on the rear of the car? Tyres would be the same size.....

I would say so, yes. When cornering, i think youll find its easier to corner one way than the other.

if noticed should fail mot, think i may also feel different at speed round corners due to the side wall defection.

Doubt you'd know the difference or if it would be noticed

Apart from foobarring the handling it would be an MOT failure

I have to disagree with the posts above.
half an inch is not a lot when it comes to wheel width. You can use the same tyres on different size wheels.
example 7.5j and 8j you could probably get away with using a 225 tyre. As MOT standard you may be ok as I don't think wheel size comes into it.
Tyre size however does have to be the same on the same axle.
As Woolly said if you use the same tyres on different size wheels you will notice slightly different side wall deflection characteristics.

I've got 225 tyres to fit but I did think that the side wall deflection characteristics would have an impact  Looks like i'll have to
send them back.

Personally wouldnt even consider it. You rely heavily on the fact these cars go round corners well, why take the risk !!

Probably not an MOT fail due to tyre size remaining the same. However it will affect the offset of the rim edges, so altering the effective track
width on one side. Seems a bit of a risk to take IMO - I can tell when I'm 2psi down on on tyre, not sure I fancy a whole different rim.

as its end of line then I presume there was a production run, so there should be some out there.
So I would look out for another in either 8 or 7.5 and then sell one of yours on.

If the rims are the same offset then the difference in width wouldn't affect track width. I still wouldn't though.

most chaps would be happy with an extra inch
no chance of finding another wheel to replace the ones thats too wide?

The biggest reason for not using mismatched wheels is is the offset --- the back space is likely to be the same so the wider wheel will have its
centre line 1/2" futher outboard ----- that will make the car crab under braking and to a lesser extent acceleration.
