When towing with my conversion should I set the air pressure on the van tires at the 42 psi recommended by Ford or the max setting on the tire at 50 psi. Thank you
Depends on the weight you have. Many overload their vehicles, many don't. If your within your vehicles GVWR then use the Ford door jam figure. If your over the GVWR's of your vehicle I'd use max PSI for your tire. Then we have the old chalk test right Marty :B
