R 14NS R

about to replace my tyres, always had eagle f1 s and am probably going to stick with them, however, what size, currently have 225 45 17, been told everything from 205 to 225, 40 or 45 so a bit confused.

what did they come with originally?

they are going on an sti5 type r, (dont know if that makes a difference).

thanks in advance
