I dont know if this is true or not but I think Losing weight will make you stop rubbing

I have 265/35/22 and with a full car you will rub pretty often if you go on a bump or dip without slowing down... just from my experience at least... the car isnt even lowered so when I asked the forum if I should lower the car I was told I would rub even more! I think rolling my fenders is the solution too....
Edit: Im not sure if everyone is doing this but when they put my rims on they all have this metal circle thing you put in before putting the rims and I think it makes the tires stick out more and makes it look really cool! Im thinking is that the offset?
