Anybody runn'in 32s or 33s with there stock 4.11's (Hows it work'in for ya) been runn'in on 31 KO's A/T tires since last yr, and they did really well with my 2.4, NV1500 5 speed, and 4.11s. Yeah the funds dont warrent the gear swap yet, but would like to go with a little bigger size tire untill i can rig up an 8.8 with 4.88s
-
I'm runnin 33's w/a 2.5 and 411's.. Havent used 5th gear since I put the 33's on.. My jeep isn't a DD and when I go wheelin away from home I trailer it.. If you run yours down the highway save ur coins and try to do the re-gear soon after if not at the same time as your tire upgrade.... I'm regearing mine come wintertime...
-
Yeah thanks man, maybee i'll just go with 32s instead of 33s, because were only talk'in an inch more of tire with 32s. East Coast Gear Supply (ECGS) has an 8.8 bolt in for the tj for $675., i believe you only need the ring and pinion, and they have that to. Only have a payment or two left to pay my jeep off, so now i plan to building my tj up bigtime. :dance:

I used to run 31's on 4.11, and even those were not optimal, but it was liveable...
-
I drove for about 5 years on 32's and 4.11's and it wasn't optimal but liveable. At least it was livable when the national speed limit was 55MPH. Now that it's 65's, I doubt it will cut it. In town isn't bad but the Interstate will suck. Honestly some decent 31's should get you through a large chunk of the trails out there. If you're lucky you can find a friend of a friend who can do gears for $75-150 an axle and then buy the parts yourself. Should be under $500 that way.

Yeah if i think about it, i do believe i recall just after i got my 31s installed, i noticed a difference when i applied the clutch, seems that i had to tach the motor up a little more to pull out. Maybee i'd just gotten used to it, because the tires that the 31s replaced, were the stockers. Probly wait now till i get an 8.8 with 4.88s ready, and just go with some 33s. Guess i'll stick with the 31s i spose :thumb:

Got 33"-s on stock 4:11.
Here in The Netherlands it is quite flat so on freeways I still use the 5th gear. When I have to climb a bridge I have to downshift.
No big deal.
The most problems I get is on a trail: in low gear it is hard to "crawl". With just a light tap on the throttle, the car surges forward.
I am thinking of re-gearing to 4.56, maybe even 4.88 although the pinion of the 4.88 might get bit small/weak.

I here ya man, yeah i use my jeep as a DD and for work mostly, and i do have some rolly polly hills to attend with that slow me down quite a bit even with 31s. The guy cross the street from me has 32s on his tj which looks pritty cool to me, which is probly why want to put the cart before the horse, but guess i'll wait till i can round up an 8.8 with a better set of gears before i go any bigger than 31s.

4:10s and 31s is livable. Highway grades will probably have you dropping to at least 4th.

5th is OD not a passing gear. You're not supposed to be in 5th on hills anyway.
-
if your going over 30 inch tires re-gearing is recommended.. if your willing to live with running 3-4 gear most of time it's your call. with 32's your going to be gearing down to 3-4 gear at the sight of any upward grade.
don't forget as well that light to light with bigger tires it's harder on the clutch or auto trans trying to get your vehicle rolling especially on upward grades.. like most said 31's are livable but I didn't like it pulling a trailer or anything or doing town driving were full constant stops are required.
if it's due to lack of funds well do what you got to do!!.
-
Yeah i guess i'd gottin use to the way my tj rolled on the 31s, did'nt think that an inch more of tire (32s) would make that much of a difference over 31s.
-
I drove with 31's and 4.88 for a while... Now THAT was an awesome setup! I now wish I had 5.13's (of course, I need new axles for that, so it's a no-go!).

:thumb: I did it on stocks for a bit!! that was awesome!!

How about the pinion of a 4.88...wouldnt that get too small for the forces that it has to withstand?
Id like to keep my stock axles and regear to 4.88 but fear the weakness of the pinion...

not by much, but it's weak to begin with - it's the tooth dimensions that matters most (the shear force that it can withstand).

Thats what the big complaints about, sticking a wod of $$$$$$$$ into a crappy axle like the D35 :deadhorse:

It's not really an issue.

:rant: Know that, but can tell almost all the traffic, either-side, is taking the highway hills in top-gear or OD. Wanna be like them ...they're probably going :hahaha: when I have to downshift
-
I have 4.88's on 31's and must be in 4th on most of the steeper highway hills. On a couple of the hills of the 14 North of LA I can barely hold 55 in 4th gear. I generally have no problem with freeway driving as long as I don't expect to be doing much over 60-65.

I have wheeled the snot out of mine and have yet to have any issues. In fact, I changed the rear ring and pinion thinking it was the problem from my last wheeling trip, and it ended up being the drive shaft, not the ring and pinion... And I wheel with lockers and chains (for improved traction on mud) on my 33's, so they do get beat on.

I doubt that. Even when I'm driving a car I've got to downshift for the Grapevine. Unless it's an auto without an OD then it sits in 3rd. In the Jeep, with my 35's and 4.56's I had to sit in 3rd as it gets steep and 4th was a bit too high. But if I wanted to stay at 50-55mph I had to rev it up to 3000 and hold it. With the skinny 33's I suspect I'll be able to hold 4th.

I could see doing some skinny 33s next tire change. Doesn't look like the Firestone Destinations I got last go around come in a "narrow" 33" size, though. Ticks me off because those Destinations have been decent on/off-road, wet/dry, and they even seem like they are wearing well.
So I'd probably do skinny 33" BFGs next go around
I can handle downshifts to 4th. But using 3rd and turning 4000-4500rpm to keep pace with traffic up highway grades at 65-70mph for any length of time -- definitely the case when driving from LA to Las Vegas, and maybe like when driving from LA to San Jose/SF/Oakland, and back -- makes my "squirrels" scream, maybe makes "them" burn up a little synthetic motor oil and definitely makes it feel like I am "wailing" on a 1970 Toyota Corolla rental with the 55hp 1.2L...Miserable deal :deadhorse: :biggrin:

There are only a few companies that make skinny tires. The most variety are from BFG. They have the 33x9.5 KO's 33x10.5 KM and KM2's. There are also 255.85R16's.
If you want to be doing 65-70 on the Grapevine then I suggest an engine swap or else get a second car.

I've got to head up to SF/Oakland/Berkeley later this month for work. Am either going to fly, then rent when I get there or drive a rental all the way up and all the way back. Probably going to look at renting a Town Car or Crown Vic if I'm driving round-trip...

When I head to LA, I usually rent a car up here and drive down. I usually get the compact, one up from the sub-compact. The subcompacts get blown around too much on I5. I really liked the Mazda 6's that I've had in years past. Earlier this year I got a Ford Focus which wasn't bad though. A lot better then the older GenI Focus I rented once. Loved the mileage. I was getting 37MPG by driving the speed limit.
Although when I get AC in the Jeep, I'll probably drive the Jeep. I think I'll be able to get into the 20's if I drive 60-65MPH with the new tires.

Me I just bypass the Grapevine and go thru Lancaster and go down 14 or 138 depending on where I'm going down there. That gets me by a lot of the traffic also.
