Increasing Tire Size
I have a 2012 JKU with 23S package... Whats the downside to upsizing tires? I have the 3.73 rear gear....

I know i have the clearance to go up a couple sizes but what is the true downside? Is it bad on my tranny/transfer case etc? I know my MPG goes down and my gearing changes so my power changes but does it really do any damage as I've heard some people say...?

I know this is a really stupid question but I wanted to ask the people that do it...
