I have a 2022 RAM 3500 with LT 285/60/R20 122R Single Rear Wheel stock tires. I am getting ready to pull a fifth wheel trailer and looking for tires that will support the load. My current 125R tires have 3638 lbs load limit. Any recommendations for tires with 3900 - 4000 lbs rating that will fit the RAM truck? The truck is a 6.4L HEMI with 4.10 gears. Thanks
