LT265/75R16E's and the proper wheels will make it an usable setup. The GM wheels (6.5") that the OEM LT245/75R16E's come on are technically not wide enough for the 265's, which call for 7-8" rims. I believe my OEM 265's came on 8.25" Dodge rims. As Russ stated the LT265/75R16E will provide 6830 pounds of tire capacity for the AAM rear axle, which happens to be the same axle used on the 3500's. The air bags will keep it level. Snowbird parks are full of 2500's GM towing really big trailers.
