2020 Non lifted RST wheel offset and tire size

[puppykat33]

Hi All

I have went through the wheel and tire thread and cant seem to find the answer im looking for. I have a standard 2020 RST 4x4 with 20in rims and want to get the Fuel vapor wheels and want to know what offset to get and what the largest tire size i can get with that offset without cutting or lifting the truck. IE can i get a -18 offset and run 275/65/20s or do i need to go with +20mm offset and get the 275/60/20s or will the 65s fit on the +20mm offset with no rubbing? Thanks for the help

You probably already have an answer, I don't know the details, but any decent Tire/wheel shop, or even website like tirerack.com can provide what you need without you needing to figure it out.
