Best tyre size for Nimrods?

[tigerstyle]

You know the 306 track width is the same front/rear?

So if the rear needs spacers...then the front does too!

I'd disagree, the wheel arches front to back differ, so spacers on rear does not equal spacers required on front. 
For aesthetics but more importantly handling keeping it as Peugeot made it has its merits as Welshpug mentions, but getting them fitting it step 1, final tweaks stage 2. 

...I'm not going to compare my fwd Peugeot 306 to a rwd 911!
