Topic: Gearing Opinions

[sharpxmen]

The bigger the tire the more the rolling resistance is an issue, believe it or not My Jeep had the worst milage on cooper stt's 33x12.5 14mpg then I went to 32x11.50 mtr 16 mpg then to 35x12.50 Baja mtz's 17-18 mpg all with the exact same gearing and lift and same driving style and the MTZ's are a hair over 13" wide so go figure The stick out nore than any other tire I had on the Jeep so it's more rolling resistance than anything else and serious mud tires have terrible rilling resistance because of the big lugs

i think i just figured out what my next set of tires will be

by the way..can anyone give me a rough idea what the 4.56s will "feel" like driving wise? how will it be off the line and time to get up to speed on the highway...how about offroad?

Here is a 33/10.50 KM2 on a YJ. Not sure of the backspace on the wheel. They are a MT wheel. I would guess about 4 inch.

i checked out some on jeepforum..they seemed a bit wider and claimed to be 33x10.5 these seem to be a bit narrower then what i expected. some of the33x9.5s on jeepforum looked like that. u sure those are 10.5s?

Yep, I didn't get a PIC of the sidewall but they were the 10.5 on the 9.5.

i guess it depends on the tread pattern and if you have em spaced out or not. i went back to jeepforum for a quick look at 33x10.5s they look good with a nice tread pattern and look good if they're spaced out a bit. ill space em out like my 31s are now..maybe hang .5" outside the fender. i find when they are directly under the fender they look too skinny and narrow.

Nice!! I wish I had gone with 10.5's I feel the 12.5's a little to wide.

That has to be at least 3.75".  Should have stayed with something around 4.5".  AEV uses 4.75" which is close but looks nice.

BTW: those definitely look like 10.5's.  You have to ignore the sidewall tread and just look at the contact patch area.  Also, the width measurement does not include tire bulge.

4.75 to push the wheel out more? if so then these would look pretty good. most of the 33x10.5 ive seen are tucked directly under or inward of the flares. with a lift and a skinnier tire like that, id tend to think that may make it unstable. i like a nice squatted look so i would push em out to get at least half an inch out from under the flare.

I have a 97 TJ 4 cyl. auto and I put 33x10.5x15s on it last summer, I have been thinking of regearing to 4.56 but overall the Jeep doesn't do too bad with the stock 3.73s. Most of my driving is on high ways and once it gets up to speed it seems to run just fine, it just takes a while to get up to speed. As far as rubbing, bumpstops are the key IMO years ago the trend was "lift it high", now days though people have figured out that a low COG is key, just extend your bumpstops so your tires can't rub limiting your up travel. Last week I put a 1.75" spacer lift on a 99 TJ, the guys showed up on stock suspension with 33x12.5x15s he said they didn't rub, but then again he hadn't wheeled it either.

do you have pictures-especially directly in front and behind-of your jeep on the 33x10.5s? id like to get a good idea of how skinny they are going to look. if i settle on these ill prob space em out to get at least half an inch out from under the flares.

No, to bring the wheel in.  I'd rather have stock flares and the tires sit under them.  I'm not a fan of wide flares.

i dont like wider flares either. i use the stock flares as a guidline of sorts and i prefer to push the tires out from under them at least half an inch. i feel it gives it a wider stance and looks a bit better with a nice squat like that.

[Jeffy]

Most stock wheels are around 5.5" BS and adding -1" makes them just stick out.  I would go with no less then 4.25" and 4.5" is probably the best compromise.

I will try to get a pic from directly behind the tire today, those are 33x10.5 on an 8 inch rim with 4 inches of back spacing.

I dont mind my wider flares.  I think they look very well, and cover just right my 33X12.50.







But I guess it's just a matter of taste...

Here are a few better pics to show you how mine look in relation to the flare. Honestly I always liked the look of 33x12.5s but I bought 33x10.5s because I wanted to help my little 4 popper out as much as I could. Now that I have been running them for a while they have grown on me and I like the look now. I run 34x10.5 Swampers on my xj trail rig but it's a beater and I don't really care about how that one looks.
