If say for example I wanted to run a set of alloys that measured 8.5in on the front and 9.5in on the rear, what size tyres could I safely run without worrying about rubbing?
My chart gives these sizes:
8,5 Inches
Minimum Normal Maximum
225 mm 235 or 245 mm 255 mm
9,5 Inches
Minimum. Normal. Maximum
245 mm 255 or 265 mm 275 mm

If the car is lowered anything over 235 will rub the fronts :-\

Some 235/45/17 tyres on factory wheels rub. These, from memory, are 7.5J. Without looking, I don't know what the ET of factory rims are.
Some 245/40/18 on Irmscher Sportstar ET30 will rub.
8.5J, I think you *may* struggle, but depends on the offset. But it may be too tight to avoid the wheelarch at one end, and strut at other end of the offset scale.

17"s are ET33 iirc :y
My 8J 18"s have 245/40/18s fitted, ET33 and no rubbing, but set up is standard Plod :y
-
anything over 235
* handling will be awful (especially on a lowered car)
* will cost serious money with premium brands
* not worth it because will losse acceleration performance
* will probably tramline
imo :-\

Not wishing to be difficult ::), but mostly wrong IMHO :-\ Only thing agreable is that tyres can get pricey :y
But Paul probably already knows that ::)

I have tried many monster bimmers (v8-v12) with those monster tyre sizes.. and even those cars become awful with those tyres..
let alone omega :-X

Tyre cost isn't an issue, otherwise I wouldn't be considering it! Cheers Al ;)
Always make me chuckle when you get far more Information than you even asked for lol... Thanks for your concern tho :y
Wheel offset is yet to be confirmed, with the possible future long term plans I have I'm gonna need something to lay a 'certain amount' of power down ??? And the car is lowered about 30 - 35mm at a guess, not quite sure tbh ::)

Paul,
I had 235/35/19 tyres on the front about 4 years ago. The wheel was 8.5J at 35ET - no problems with Rubbing at all.
I think you'll have problems with rubbing if you go wider.
I had (at one point) 275/30/19 on the rear. It was excactly the look I wanted. Living with it on lowered suspension was some thing else entirely........
Rears should take 10J

IME, 30mm is about the absolute maximum for regular road use. Even that is probably too low for the rear. Problems are speed bumps, getting over dropped kerbs onto slopping driveways, the ramps in multistorey car parks etc.
Obviously, if its a show car, none of the above will apply :)
