I have been running 35x12.50x17 toyo AT3 on aftermarket rims on my dually for 4 years and haven't had a problem with them.

I also run a spacer on the duals, pull a 20k pound fifth wheel toy hauler every other weekend during the summer, and make a trip every year in November to Florida from Arkansas, pulling the same fifth wheel.

Just make sure you have a good spacer for the duals.

I switched to 20-inch aftermarket wheels and tires with no spacers (for a different look), and I'm running 35x12.50x20 Toyo AT3.
