Thanks for the help and advice guy & hzrd. Sure helps researching into my original post:

g'day everyone and i hope this is the right area to post this question. i am finally up for new tyres on my 2002 Sri which is currently sporting the original Michelin Pilot HX 205/50 R16 tyres.
would it be wise to replace them with the same tyres or can anybody recommend a suitable (i.e. less pricey) substitute.
i would appreciate any advice, thanks.
