Jul 13, 2011 · Manufacturer reports the maximum ground pressure on the same axle (loaded) is 22.7 psi. Based on data I've seen from a tire manufacturer for the 29.5R25, the 30-mph load limit at a cold inflation pressure of 29 psi is 16,500 pounds. So I have: Equipment Manufacturer: 26,635 pounds produces max ground pressure of 22.7 psi
