I am currently using 195/55/R15 on a 6.5jj rims with a +38 offset without any fender hitting issue, if the car in your profile pic is yours and you are using that rim, I would assume the rims you're using is either offset +30 or 35, what suspension are you using now? If you're using stock absoerber with lowered springs, there is a possibility that the springs soften over time, it really depends on a lot of factors :)
