hi, recently ive been driving atos with 13 inch tyres. no matter how i pump in air (usually 205-210) it will still look slightly deflated on all tyres (didnt happened on my other cars with 15 n 17 inches). theyre not so old n no punctured or anything. may i know how hard a tyre should be on this kind of car..? if too lembik, might lead to high fc, too hard, i guess will skid n terbalik....
