hi can anyone tell me if i can fit audi a4 wheels to my skoda superb?

Yes they will fit, they both use 5x112 with an ET of 35 - 45.

(that is assuming they are OEM wheels, if not then check the ET on them)

cheers mate

All those numbers looked decidedly foreign to me.

What do they all mean?

5x112 PCD = 5 studs (wheel nuts/bolts) that are 112mm Pitch Circle Diameter.

The ET is the offset of the wheel (from the center of the wheel)

So in the diagram below it would be 7"x16", 5x112PCD, ET37

HTH

I am considering a wheel upgrade on my superb mk1 and have seen a set of 18 inch audi wheels with the correct stud diameter of 112 but an offset of 54... will this give me a problem with fitment....?

You wouldn't rather have a set of anthracite Zeniths with ET51 would you ?

(Depending on the width) ET54 is too much for the MKI Superb, i looked into some MKII Octavia wheels that were 7x17 ET54 (IIRC) but the offset was too much (without spacers and longer wheel bolts)

That's true.

ET54 doesn't fit on Superb. I have tried.
