Wow ! Thanks
i am still lost when it comes to this, between the sizing and offset I am just going to not change anything. There has to be a chart somewhere that shows you what will work/fit without changing suspension geometry and requiring recalibration of your speedo.
I have stock 20" on my big horn by window sticker says they are 20x8 the tire size converts to 10.8" wide (275/65R20) I am not sure what is right. I cant find the stock offset either.
I just want to put some 24" SRT replicas on it, they are 10" wide and +25.4 offset on them, I am not sure if they will stick out further or what size tire i need to not screw with my speedo. I guess this is why dumb people (me) pay smart people to do this stuff for them.
The diameter of your wheel has nothing to do with your speedometer , the diameter of your tire will change the speedometer . If you get the same diameter tire you'll be fine there .
As far as offset , maybe a smart guy will chime in that knows the offset & back spacing of your stock wheels and the replicas you want . I'd say most likely your 20x8 wheels are a + offset or " 0 " even though the replicas are 10" wide you say they are + 25.4mm offset = you'll most likely only be approximately 3/4" to 1" further out @ the wheels , this will also change with the tire width you choose ...
Come on smart guys where are ya ?
found a web site that will break down all the math if you get all of your info for your old and new setup.

Rims and tire issue
I have a 2016 ram 1500. Stock size is 20x9 with a 275/60/20 tire. I am putting in a 20x9 rim and same size tire but the offset is -12. Will these rub if I don't have. A level kit installed. Everyone keeps saying you have to put them in to see
That set up will work , the only possible time you would rub would be in Drive or Reverse @ full lock combined with a bottoming out bounce over very rough terrain.
So if you do not normally BOUNCE through rough terrain @ full lock Right or Left in Drive or Reverse then you will be fine .
I won't be going over any ruff terrain and we don't get that much snow. Full lock is 4 low I'm assuming
Sorry , full lock is the steering wheel full right or full left
Ok yea no rough terrain just normal street
Here's where I am to be a pain lol. I currently have 20x9 wheels with oem fitment of 275/60 on them. I'm on Bilstein at 2.1. I want to go with a 295/60 tire to give a slighter fuller look. I don't want off road/ mud tires as I don't do any of that. My current tires are Michelin LTX which SUK in the snow even with 4x4. Does anyone have 295 or even a narrow 35" tire on this set up that they are willing to post photos and thoughts on please ?
