Tires and gears

So I was bored at work today and decided to check my gear ratio to see if I could run 33s. Unfortunately, I have 3.07 gears...how would that handle with 33s? I don't want to waste money on tires that I'm going to hate

Driving your rig will be an unpleasant experience with 33s and 3.07 gears. Either regear to 4.56 or stay with smaller tires.

Agreed, I have 3.73 with the same engine/transmission and 5th gear is useless. The engine lugs pretty bad even at highway speeds in 5th. The second I hit any kind of incline I have to downshift, and floor it just to keep speed. I usually just leave it in 4th. I could only imagine how bad the 3.07s would be.
Also, don't know how big of a deal it is, but cruise control for me is useless as well. I end up having to downshift pretty often so unless its completely flat and straight, I don't even consider CC.
Not saying it's not doable but I certainly wouldn't reccomend it until you regear. A regear is basically the same cost as a new set of 33's (maybe a little more) so maybe hold out on the bigger tires until you can do both at once.
Granted, it would be easier considering you have a manual as opposed to auto.

Rubi with metric 33 and stoch 4.11 and 5 SPd where both cruse and 5th good even with uphill at 7000 ft above sea level

My 98 with 4.0 5 SPd with 4.55/4.56 and 33x12 Al's fine in 5thup hill at 7000 ft but not as pleasant as rubi above 65 mph on highway

If only ion road I would go with the 411 but if mostly off road go with 4.55/4.56

Since regearing plus tires and wheels would be too expensive for me (I'm only in high school) I'll probably end up getting 31s.
Still...33s look awesome...all in time I guess

I was in the same boat, went with 33's and just saved up for the regear. Definitely worth it

I've got 3.55 gears and 33" tires. It's not really as terrible as it sounds. Sure you do a lot of 5-4 shifts when hills come about, but all cars downshift when a hill comes. I'd only regear it if you'd be doing much off-roading.
+1 for CT!

I did that once... Only I had 35x12.5x15 procomp x-terrains. Not fun on the highway!

I've been running 33's with 3.07 gears for 3 months now, I don't find it a problem ,
My Jeep is my DD + monthly weekend wheeling, the drive to work is all on the flat town driving.
Ok when it comes to a hill at normal road speeds it just dies and I have to drop a couple of gears.
It wasn't a sports car before I put the 33's on it and it's not a sports car now.
Most of my wheeling is done in the lower gears or low ratio so there's no problem there.
To the original poster if you aren't going up to many hills out on the road then just go for the 33's, save for your regear, its cheaper than running 31's then paying out for a regear and 33's

I am running 33s with 3.73 and like stated above 5th gear is worthless. I don't do a lot of highway driving but if we do we take the wifes trailblazer. I will be like a kid on Christmas morning when I regear. But I am hopefully going to an 8.8 instead of the D35 and I'll regear then for 35s, no way was I going to pay to regear twice.

You could look for a set of rears out of a 4 cylinder TJ. They all have the 4.10 gears in them. I picked up a used front D30 out of a 4 cylinder with 4.10 gears for $250. Less then the price of a re-gear.

I think it is funny when people with 5 speed and 3.73 say 5th is 'worthless'. I use mine all the time...

3.07's are quite a bit different from 3.73's. With 3.07's and 33's he wouldn't be shifting to 5th gear until at least 60-65mph, and would be down shifting at the slightest hill. I ran that set up for several months and hated every minute of it.

I don't disagree. That is quite a bit different. I am all in favor of the OP regearing. I was just responding to the 3.73'rs

My 98 had 3:73 and 35s and I thought it was fine. I think it's actually a great ratio for doing 75 on the highway. Around town was fine too. My parents have a dirt driveway and when I lived at home, I used to drop to second or third around the dirt corner and punch it, I spun those tires and drifted (we called it fish tailing) drifting wasn't a house hold name yet! I actually met my neighbor around That corner mid drift once, she was a teen and didn't see me. I pulled to the right and stopped, she hit my front drivers side tire and dented her fender in!!! Haha 3:73 are great! Here's my 98 with 3:73's

Yeah, i have 35's on 3.73 on my 4.0L so far i really like it. Ideally it would be nice to upgrade but oh well i am not too picky. As well i have a buddy on 3.07 gears on 33's i was out in his jeep yesterday, it has no issues really pulling 33's on the road, however offroad you want some more torque for 4HI, in 4LO she is perfect, so basically in my point of view, you can just stick her in LO when you go offroading, or get used to her trying to stall more in 4HI, up to you. I drove my 4 cyl around offroad in 4lo all the time ( offroad ) and never had a issue at all
