Confused on tire recommendations for Monty 3670RL

[Winmagbar]

Hello,

Newby here and it looks like I need to change the tires on my new to me 2003 3670RL due to age and some that are Marathon branded. Reading all I can in the forums on this subject but I don't mind admitting I'm a little confused. I have found several conflicting weight specs for my trailer with 10,350 lbs being the most consistent with 3,600 lbs carrying capacity. Are those numbers accurate? And what is the stock axel rating? Based on those two numbers then, what would be the tire recommendations for safety, LT or G rated tires and recommended size? I want to buy tires in the next two weeks before a long trip so your help would be greatly appreciated. I know an accurate loaded trailer weight would be best but I am nervous about towing the trailer to a weigh station with these tires.

Thanks

Robert
