Hairpins on a rover 45

Hi all,



Just picked up some hairpins for my R45.



I'm not sure if the current tyres, which are 205/50/16 ( i think), will rub, as I've seen a few posts of people talking about 45 being better then 50, but i'm not sure if that applies to the Rover 45, and I understand the ZS did come with hairpins as an option?



Also I read on here you shouldn't use the same wheelnuts from my current steel wheels, if so where can I purchase some for alloys?



Cheers
