bought these wheels, they are ford fitment and have track tyres on, how do i tell what the offset is, and what should it be for a safcoz, one is slightly different style but the guy says they are the same its just the style that is slightly different,want to use them for croft but need to know if i need spacers etc

 

It normally says on the wheel. If you look in the area that is on the right hand spoke on the bottom photo, it normally gives size and ET.

 

right it says 6j x 15 et15 what offsett does that mean and what should it be for a safcoz mike???

 

No that is not.
Also one looks different to the others....ie different offset

 

Check all the offsets on ALL the wheels before parting with cash.
Take them to a tyre fitter and get them balanced.
They 'll go on if they are 4x108 et 35 but stick out a little bit further than the normal sierra ones.
Check the centre bore is 63.4mm other wise they could be peugeot ones

 

all the wheels have 6j x 15 et 15 on them , so are they ok and whats this 4 x 108 et 35 your on about, the one thats different is a slightly dished wheel wheres the others are flat but the guy says they are the same offset and will be ok, how do i check the offsett if the numbers i have found are not the ones i need???

 

4= number of holes
108= distance between the holes in mm i.e. 108mm apart from centre of hole to centre of hole opposite on 4 stud
63.4== the centre bore of the wheel on the mounting face.
ET is the offset which is the distance from the vertical centre lineof the wheel to the surface of the wheel mounting face measured in mm
The smaller the offset the further apart the wheels ie et15 will stick out away from car and et 35 will be 20mm inwards- ideally where a sierra should be.
You can obviously fit the et 15 on but it will widen the track and may upset the handling and where tyres prematurely
Also the important is to measure the centre bore . If it is bigger than 63.4mm then the wheel will 'float' and not locate properly. If it is to small the wheel will not sit flush to the hub

 

aaaah, now i see, thanks m8.

 

Also, ET15 are gonna stick out about an inch outside the arch!

 

hows that if the offset is only 20mm different??? , fukin confused

 

Just to clarify - COMPLETELY THE WRONG OFFSET - you've been shafted .

6 x 15 is smaller than the standard wheels . Were they off a Pug 205 or some such?

 

My guess is Escort Cossie rally car..............

 

Could be , they do use silly minute wheels for snow / gravel tyres....

 

Snow tyres / wheels would be ET 5 on 6j rim
Either way as Mike said (he likes the word shafted)
Try them anyway.
Pon was exagerating as usual....remember his 6'' cock turned out to be 2'' (according to his missus) & (Mike)

 

they were off a fiesta wide arch rally car, the rims are mint and the tyres are ok but seeing as they are wrong, dont really matter so theres nowt i can do with them, e bay here i come

 

Really Chris.

So the ET15 wheels I had didn't stick outside the arch nearly an inch then

Or the Compomotive rally wheels I sold off of my car weren't 6jx15 ET25

 

About an inch or nearly an inch ????
and did I say compomotive did n't sell et 25'' wheels that were on your saff??
Any way I think we are ALL right

 

Nope.

You're wrong.

On so many levels

 

well, went out and had a go and they went on and dont seem to be a problem, havnt drove it yet but the tyres are really bulbous so might need to adjust the arches a little, but not much, so just goes to show ya never know
