    33" tires with a 3.73 gear ratio

    Is anyone out there running 33"s on an LJ with the stock 3.73 gearing, and if so how much power do you loss compared to running 31" tires?

    I do on my tj. Its semi heavy with a winch armor and steel front and rear bumpers. Probably close to what an lj weighs. I can still use 5th gear on the highway. On the trail I wish I had 4.56s though. It is liveable with the 3.73s in 4 low

    The jk sport comes stock with 3.73' and 255/75r17 which comes out to about a 32 and its just fine. But it's a different engine so everything i just said may not even matter.

    3.21's are standard. Certain packages come with 3.73's.

    Mine is a sport as well. I'll have to dig out the window sticker but it has some package that adds them. And mine is a base model, I don't even have AC.

    HAH! I have AC in mine but hardly ever use it since my Jeep overheats when I turn it on. Fins are full of mud oh well its easier to pull the doors and windows and leave the top for shade and cool off that way.

About us
“wayoflife” is a moniker that I’ve been using for 20 years now and I chose it because I think it does a great job of explaining, in simple terms, the passion I have for Jeeps and the Jeep way of life. This is a lifestyle that transcends age, gender and race as the only thing you need to be a part of it is a love for the outdoors, a desire to explore, a yearning to take on a challenge and a will to conquer it. Over the years, Cindy and I have attempted to capture the essence of this lifestyle through photographs and videos and share it with others around the world. And, this is how WAYALIFE was born.
