wide fenders

I have a car with wide tires. occasionally rub on the edge of the rear fenders. What I can do?
its a 1996 Honda Accord. the tires have a 2 inch offset, protruding more than usual and when I get some weight on her back rubbed. what is a cheap way to solve this problem?
Replace with correct size tires for the car.
