wheel pattern, 5 x 112mm??

[mikek]

looking for after market wheels for my us 280i, i was told that the lug patter is 5 x 112mm. is that correct? im thinking about replacing my stock wheels w/ 15" or 16" after market wheels, what should i be looking for in regards to backspacing?
thanks

Stud spacing is Ford Granada. Offset is cast into the inside of the wheel. 16" wheels will make tyre choice a lot easier and handle better in the dry/track. I'll look up the details if you're struggling.

I thought that this might help.

The situation for 280i cars is even more difficult because I do not think that anyone makes a current high performance tyre in a 14" diameter. I think that Falken still make a reasonable 205/60VR14 which is used by some sprinters.

The original spec was a Dunlop 205/60VR14 up to chassis number 5321 (part No. 025g002A) then a Goodyear 205/60VR14 from chassis number 5322 onwards (part No. 025G010A).

To use a modern high performance tyre construction it is necessary to change the tyre dimensions slightly. A 205/50VR16 should be fine all round and a 225/45 should fit at the rear, both of which are a nominal 1.5% increase in rolling diameter.

There is not normally a problem for small deviations with specifications higher than OE. You should certainly tell your insurance company.

you can easily measure the PCD of the hub studs by measuring across 2 adjacent studs (one 'edge' of the pentagram) then subtract the width/diameter of one stud, then multiply this figure by 1.7013 to give the PCD.

But would you be confident about your maths and measuring ability to give an accurate answer. Sure it can be done with callipers but take care.
