Really? First post. April 1st? Nope.
If you are serious, I honestly hope you are not... 305's will rub AFAIK. Also, factory OD of your Acadia (not Arcadia) is 31.05", the new size would be 32.41, way too big. Odometer and speedo will be off a fair bit. Reel it back in a bit.
Nope, still too big; 32.13" OD
Also, about the widest I recall seeing with little to no rubbing is 275 (others will chime in)
There are a few posts about people running wider tires, so a search can find you appropriate offsets, etc.
255-35-24 will get you 31.03
Keep in mind this will get you much higher wear and tear on your steering, suspension, aching bones... things may start to rattle inside quicker, all that jazz.
