So my TV is a 2015 Sierra 3500 Diesel Dually. This winter I used the stock rims for winter tires and am now ready to change them back to the summer ones -but instead of moving tires, I was just going to pop for new wheels. Which made me think, time to get some upgrades.... This slippery slope now has me contemplating moving from 285/80 R17's to 3xx/50R24's with the applicable load capacity rating to handle my heavy 5th wheel (2750 pounds payload in the box, 16,500 Gross Weight.)
What I am looking at ending up with is something like this picture below. But to do that, I'm looking at a 2-3" lift kit as well. Is this going to be a big concern overall? I'm fairly new to towing, but put on over 3000 miles last summer in July, and another 1500 miles before winterizing and parking. I am looking at another 4-5000 mile trek this summer and don't want to kill performance or massively affect fuel economy, but overall, I want to have fun, I want to love the look and feel of my truck whether the trailer is attached or not.... Is this insane? Or will it be no big deal?
The Duramax has gobs of power, I'm not too worried about that aspect of it.
