Mine has 235x45 17" as standard all round.

You may find this useful, I found it earlier on today when I was considering 19" wheels:

   Hi,
      If you fit 205/40-17s they will throw out you speedo by appox. -6 MPH.
 You need to fit at least a 215/50-17 or 225/50-17 to keep the rolling radius correct.

      Hope this helps,
                            Pete :y.

^* Needs different settings applied to Instrument panel (or replacement if pre 98) and MID via Tech2

Hi,

Thanks for the replys, ordered a set of alloys with tyres at 205/40r17 but I can change them if I need too, e-mailed the company about fitting 215/50-17 or 225/50-17 so will see what they come back to me with

Cheers,
Iain
