advice me i want to change my rim from 15' to what should i change ...thx ....

Depends on how you want your car to look like. most people usually change their rim size from 15's to 18's. some like bigger rims 20's. but its all preference.
 
Heres a link to the tirerack website:

Just plug in your info about your car and you can check out some rim designs. 
Hope this helps.
good luck

when you decide on a rim size take into consideration that the ride quality will be less with a larger rim, unless of course you change the suspension also.
