New to the Forum, Tire and wheel questions

[Buckshotmckee]

Merry Christmas. New to the forum. I just picked up a 2016 Journey Crossroads AWD. I'm putting new wheels and tires on and just wonder what your guys opinion were. I have the stock 225/55R19. I'm thinking about going with a 245/50R20. They seem to be a 3/4 of an inch taller than factory size. 

Thoughts???
