If you are looking at the 10.50 width tires then they should not look much different than what you are running. it is only going to be 1" all around the tire. So if you are worried take your hand on top of your current tire around it to see how much room you will have between the top of your hand and your fender. This should help answer everything. Do not forget to turn your tires and see how much room you have with the tires at angle to your fender, but like what everyone on here is saying you should be fine.

Here is 33x12.50 with no lift. Old picture the only one I have.
