Original size wheel rubbing problem

I changed the original dimensions of my vehicle 175 65 14 wheel covers and bought the dj 350 model 14 inc 4 × 108 rims, but when 2 people sit in the back, 40 to 40 km over the rough roads or right back tire in light bumps, the car is knocking when the car is empty. ?

Although not entirely sure, it may also be related to torsion. or if the rim of the rim you bought and the meat ratio are not compatible, it may also be from it.

I do not think that it is from torsion, the tire sidewall is thick I think it should be 50/55 cheek, I have 15 rims 195/50/15.

As I said the size was not the original rim 14 inches, I thought it was offset, but the person I bought also used 206 and just rubbing the right rear tire, left back or front is no problem.

The same happened with me. When you put on the 16 307 rims, there may be a problem with the torsion.

If there was a torsion, there was no problem with the iron rim. rubbing against him.
