same size tires all the way around??

I have a Honda rancher 400 AT its a 2007 w a custom 1- 1 12 inch lift I want to upgrade to new tires. I want to get the kenda executioner on some new rims. I have now in the front 24x8x12 an back 24x10x11
I want to change to 25x8x12s all the way around. I have the stock axles on as well. Should I upgrade or wait till it breaks.
So what I want to know are there any major cons to doing this to my bike? I think it’d b just fine. Just want some advice
Thx
