Or buy tires with a lower load rating.
Friend of mine did this without even knowing it like most people do. His rear GAWR on his Ram 3500 SRW is 7,000 lbs. He went from the stock Firestone tires that have a 3,640 lb rating(enough to cover the 7,000 lb GAWR) to a 275/60R20 BFG T/A KO2 tire with a 3,000 lb rating. This essentially dropped his rear GAWR to 6,000 lbs which is 500 lbs lower than my 2500's 6,500 lbs GAWR.
Although, that sticker on the door is meant for OE tires per the law that made the manufacturers put it there. If you get something other than OE tires then that sticker is useless.
