TJ re-gear

For 33" tires on a 5-speed TJ, 4.56 would be my choice. I used to run 33" tires and re-geared to 4.10 5-6 years ago against the advice of my more experienced friends who all said to go to 4.56. I regretted that 4.10 decision within a few weeks, I was always downshifting for even minor grades. While 4.10 returns rpms back to what they were with smaller tires, you actually need slightly higher rpms to truly compensate for the bigger tire's increased weight, increased rolling resistance, greater resistance your engine is working into due to the bigger tire's increased radius (more leverage against the engine), and the fact that the Jeep is sitting higher in the windstream for more wind resistance from the taller tire's larger radius.

Thanks Jerry... spoken from one who has bee there!

Jim, go with 4.56. I run 35" on my 01 TJ and went with 4.88 and am very happy.

Which is what I am happily running after that 33"/4.10 combination I hated so badly.

Hi Bill,

The only thing that surprises me about your comment is you didn't say anything about the D35! :-)

Thanks Andy!

Yea, and to think I almost went to 4:56. Good thing I listened up and got good advise from here. You were one that really helped Jerry!

Andy

Which is pure confirmation that most of your posts have become nothing more than pointless trolls... which is why I stopped arguing with you and bothering to respond to your posts in the last year or so.

Since you have the D44 rear end, another option is the "forgotten" ratio,

D44 is on the CJ... I am doing the TJ. (I wish my TJ had the D44!)

After reading all the post...I'm thinking going to the 4.88's would be the best choice.

Highway driving only? MAYBE 4.10.

Nah, I have 4.10 on my TJ with 33's. I tend to use cruise on my commute to work and I'm saddened by how often the accelerator hits the floor on slight grades.
