Tried and tested wheels offsets (235 x 17 tyres) for Sapphire or Mk2 Hatch ?
Looking into getting some Revolution Millennium wheels.
Car is a Mk2 Sierra hatch and I assume that the arch clearance is the same as a Saph ?
8x17 rear
7½x17 front
Anyone know best offsets for arch clearance ?
Widest rear tyres I could get away with ?
Car has just been painted and has non rolled arches, would like to avoid rolling them !
Will have a 6 degree beam also if that makes a difference ?

It's 2WD with 6 degree Cosworth beam and 3 door Cosworth hubs / ARB
Will 235/40/17 fit on the back ?
I just sold my RS 7 spokes that were 7½ x 17 et 38 with 215/40/17 they filled the arches nicely but were crap for brakes
EDIT for pic,
Do you reckon white wheels would be too much with frozen white?
Got a hankering for silver as it's more period...

A 6 degree rear beam will make a difference. The wheel will go more straight into the arch, making the change of touching the arch bigger.
This is the back on my 4x4 sapph with 6 degree rear beam and 17x8 wheels, ET 35 and 215/40 R17 tyres on the bumpstop. The arches are rolled and I could get my finger in between the arch and the tyre.

What was the clearance like on the back of the wheel when it was on the bump stops ?
Looks like the 6 degree beam makes a big difference to camber change!
I would like to be able to use car fully loaded without rubbing.
ET38 would pull them in a bit, might even get away with ET40 with the 6 degree beam ...

On the fronts plenty, but on the rears not at all, I ran with no springs to make sure there was no clearance issues
That was a Sierra beam, xr arms for the arb mounts, escos 22mm arb, Granada's shafts and a Swedish 7.5" Sierra estate 3.14:1 diff
This was over 10 years ago when I fitted it all up and for 3 years it was my daily driver

I didn't really check the clearance on the inside of the tyre, but I think there was quite a bit. With higher offset wheels you should have a bit more room. BTW, it should have read:"The arches are rolled and I could NOT get my finger in between the arch and the tyre."
Thanks for all the help.
I reckon the best option would be to just by a front set of 7½x17 ET38 with 215/40/17 tyres, then try them on the back and measure for clearance to see what I can get away with...

I ran Toyo T1r and Goodyear Eagle F1.
I have Kuhmo V70a for it now, that will need the arches rolling and the inner arch massaging a little as there 9 1/4 wide even as there so square.
Fitting 235s on the back was one of the best things I did, at least it gave it a fighting chance of finding some grip.

As Ridgey says. there are so many factors that affect it. Brake bell thickness is another one. I measured 4mm difference iirc between a cast disc and a aluminium bell.
I'm running ET35s with 235 track tyres that measure up about 240+. Ally bells, 6 degree beam set at 1.5degree of camber. Arches have been rolled.

How much room do you have on the insides of the wheels ?
