I have a 37 foot fifth wheel trailer with LT 235/85R16 - Load range G tires Goodyear G614 RST - rated at 3750# @ 110psi. The trailer recommendation is to run 110psi inflation due to nearly 14,000 lb. trailer weight on 4 tires. My present rims 11 years old is rusting under the paint and am concerned that I should replace them before I have rim failure. Question: What is the difference between AM20750 and AM20768? What is the load and pressure rating of each? And which would you recommend for my trailer?
