How much air pressure should be in a 650 tire?

[GenevieveLynn]

For an empty vehicle, the recommended air pressure is between 4 and 5.5. Under the premise of not exceeding the load capacity, for bias-ply tires: the front tires should be at 6.5, and the rear tires at 7. For radial tires: the front tires should be between 6.5 and 7, and the rear tires between 7 and 7.5. Below is relevant information: Tire: A tire is a circular elastic rubber product mounted on various vehicles or machinery to roll on the ground. Typically installed on metal rims, it supports the vehicle body, cushions external impacts, ensures contact with the road surface, and maintains the vehicle's driving performance. Development: In 1839, Charles Goodyear developed "rubber vulcanization technology," successfully creating rubber that would not decompose at any temperature below its boiling point. Thirty-eight years after Goodyear's death, in honor of his significant contributions to the American rubber industry, Frank Seiberling named the tire company he founded "Goodyear."
