Okay guys, maybe it's just me! I personally would not take a near new DRW truck, and change all the wheels, just to make it more winter worthy. If the snow/ice gets to be too much for the DRW, I'd just leave it parked. I've owned new trucks/cars most of my adult life. If I needed a second truck, or Winter car, I just bought one, to be sold when I was done with it.
I know Cummins has more than one truck, that could be used for Winter, rather than mess with his DRW.
I'd sell the 18" tires/wheels, should be lots of interested buyers.
