Help needed on larger dually tires

[Mark_Z]

I still need help trying to decide on what to do!! I want to put Bridgestone Revo's on my '05 GMC dually since I don't like the General Ameri-tracs. My problem is, should I replace with the same size LT215/85R16 which look small, OR go up 1 size to LT235/85R16 and look much better, and be concerned the duals are too close together. We pull a 10,500 lb. 3 horse trailer. That would leave maybe 1/2 inch between the duals at best with the larger tires. Any comments or suggestions welcome. Need help to decide ASAP.

I had to take the Generals of my truck, with the trailer on it was all over the road..Put stock size Michelin LTX on, drives like it suppose to.
I didn't go bigger, didn't want to take any chances on rubbing
