Hey guys, who run 22” wheels, what tire sizes you have?
I’m seeing 285/45/22 then 305/40/22 and 305/45/22
What is a good fit?
When I check tire calculator it shows almost the same outer ratio with 275/60/20 vs 305/45/22,
And factory 285/45/22 is bit smaller

Would 305 55 r20 tires fit the stock 20 inch ram truck wheel? I have a 2014 ram 1500 big horn with the stock 20.

I was wondering that too, how wide of a tire can you put on the stock 20" rims?
