Hi,

So the standard 18s on my XK8, tyre size is as follows -

245/45/18 front
255/45/18 rear,

What offset are these?

I want to put either 19s or 20s on it, Do i still use the same offset, and what is the required tyre size if
I do go with 19s or 20s?

Will 20s make it look like its on stilts, thus meaning it will need to be lowered?

Cheers for any replies,

 

Measure them yourself.
