Tires B motorhome

I have a 2005 Gulfstream VistaCruiser Sprinter Van. When received it had 225x75-16 BF Goodrich and they were in good shape. I was diligent to make sure proper pressure was in each tire. Within the first 10K miles we had it both rear tires overheated (I think) and bulged and blew out. I believe these were too small for the load no matter what the Manufacturer says. I went with 245x75-16 Pro Grade Goodyear Silent Armor and I am totally pleased. These ride about as well as you could hope for in a truck and have little road noise and give great traction. I keep them pumped to specs and make sure to balance and rotate every 10K with the oil change. After 15K miles I see no wear and feel much more secure. I do not get much sway with the wind but do get swerve on occasion. The Mercedes active traction control helps with this.
