I've got a 2007 2500 diesel. Love the truck, except for the puny looking donuts they put on it. I want to upsize to 20" but I don't know if the truck's handling would be compromised. I pull a travel trailer and jet ski, so obviously, safety is still a priority.

I know I'll have to ahve the diesel re-calibrated if I change the tire size.

Anyone have any info or a place to point me to?

Thanks!
