Hi all. I'm a new member and this is my first post.
New truck owner here and I've discovered this forum and thread recently. I picked up a 2020 Limited 1500 with the "Black Appearance" package which includes the 22" gloss black wheels and 285/45R22XL Goodyear Eagle Touring . My options include: Bed Utility, Limited Level 1 pkg, Pano sun roof, 3.92, anit-spin, 5.7 hemi + eTorque, Rambox w/ cargo divider, brake controller, factory Tri–Fold Tonneau Cover (came with appearance pkg) and that beefed up multi-function tailgate and I'm at a depressing 1061 lbs on the yellow loading sticker.
I bought this with the intention for towing a ~6,000 travel trailer that I'm still in the market for buying. Most of the dry hitch weights of the trailers I'm considering ( Lance 24 series) are between 550 and 665 lbs. With just my wife and me and nothing else we're pushing that top 7100 GVWR limit.
If I remove the tonneau and the rambox divider and put them in the back of the trailer I gain back nearly 50 lbs. Moving the truck spare tire to the trailer gives me back another 90 lbs. Now I'm considering at buying a set of lighter wheels/tires. I see on Tire Rack They have a 20"x9" Granite Alloy that's only 25lbs. Looking at most the the 275/55R20 all seasons that fit that tire they are also a at least 5 lbs lighter than the 22" Eagles I have now and have a higher load index to boot (2,892 lbs over the 2,601 lbs on the 22"'s). I haven't weighed the OEM 22x9 wheels yet, but I'm guessing there at least 45 lbs. I can see gaining back another 90 lbs of payload by switching over to the new set of 20"s
Would there be any issues with switching out the 22's for 20's? I'm looking to give me some headroom for keeping it legal and safe with a trailer that conforms.
