new tires. do I need to regear?

I am getting 33x12.5" tires really soon for my cherokee. I was wondering if I need to regear cause of the size of the tire? it has 3.55 stock gears aw-4 automatic.

thanks

You don't need to, 33s will still pull good with 3.55's. Once u go beyond a 33, it becomes much more important. If you do decide to regear, go as low as possible to allow for bigger tires down the road.

what about a 4.10 gear later on?

Either 4.10 or 4.56's would be a great choice.
