Changing gears on my '98 YJ Wrangler

I am a new Jeep owner; purchased a "project" '98 Wrangler YJ that needed a lot of TLC, cleaning up and some cosmetics. I replaced the tires with the same size tires it had on it: 33x12.50/R15. (oversized for the factory original specs) The Jeep has a 4" lift. The little 4cyl engine works hard with these tires, and I know that I need to re-gear the jeep. Is there a manual or reference guide that I can consult that already has the math worked out on what gearing/gearing ratios I should order to put in my jeep. I know that whatever I purchase I will have to buy two sets if I ever want to use the 4-wheel drive, but I have to do this to get the jeep driving better.
Thanks in advance for any comments or suggestions.

Assuming you meant "95" in your post. There are many charts out there. Here is one of them. Google search is your friend. Here is an RPM calculator as well.

If you want more information about re-gear pricing see my post in the vendor spotlight here! <<< "Ctrl + click" for a new window

Thanks for your comments on regearing. I will consult with a friend who is going to help me with changing out the gears. I may need to ask some additional questions, but your charts are a huge help. DFM

AOR, I still haven't pulled the trigger on re-gearing my jeep. You are correct that it is not a '98, it's a '94 YJ. I am going to be using the jeep for driving around my small town, to a cabin in the woods (hard pan GA red clay) , and some off roading on trails and swamp. Judging by the chart you posted several months ago I am assuming the 4.88 is what I need. Can you give me a price and tell me what is included in your kit. Thanks man.
