Thanks bro... thanks alot.... i think I should probably go for 195/60/R16 then... this is the genuine tyre size on indian city... its difference is abt 1%...
as for my 04, she has been drive alot but i keep good care of her... thats why u can see that the lights and the body shine, not like genuine, but look 95% new... 
can u show me some pics of ur idsi???
and the post of another bro on our air vents is useful... i'll try... will search for a similar brush in the market cz i m far away frm having a biwi...:D:D:D:D:D:D:D
God bless u and best of luck for ur exams...
