Hi, I’m hoping that someone could help me. I am upgrading my 2017Denali HD 20” wheels to 22’s and I’m wondering what size tire to go with. There are a few issues I guess I run into by doing such. The first is load rating. I guess there’s only a few tires that meet the factory load rating so I would be losing some towing capabilities which I’m fine with as the truck is a mall crawler, but I want to be safe. The wheels are KMC 825 buck 25s with -18 offset. I want to run either 305/45R22’s or 33x12.50R22. From what I’m told, half my sources say that the 33’s will rub at least on the lower valance with that -18 offset but then half of my other Google search and show that there is no issue. The truck is going to be leveled on a 2” SuspensionMaxx kit. To be safe, one could argue to go with the 305‘s to avoid rubbing but the issue there is they are 4 ply tire and are only rated up to 50 psi. I’m not sure how this would affect the ride and the safety. The 33’s are a 12 ply tire rated higher than our 10 ply stocks. The tires I want are the Nitto ridge grappler‘s. Does anybody have a similar set up with 33’s on a leveled Duramax either LML or L5P? Any help would be appreciated.
