Tire width/bed side hitting

[Rednek13x]

Just bought new wheels and tires, got alot of work done on the bed, set it on the frame to park in the shed for a while and come to find out the bed sides hit the tires. Held a fender up and the tire is close there too... too wide of tires..?

Any ideas on what i can do, id love love love to keep these tires and wheels. i dont really want to lift the box up and the body lines wont line up, look goofy. any ideas? How is everyone else running these big wide tires? 265-65-18
