Correct gearing for 30's on an XJ

Hi,

I have a 4.0L 5sp 1990 cherokee, and I would like to know if the stock gearing is sufficient for this application, of if I need to drop down when I put 30's on ?

Thanks in advance

stock is sufficient for 30s. Save the money to regear when you get bigger tires.

it is probably a 3.73, 30s are only 1 inch over stock, when they are bald they will be just as tall as new stock tires.
