33x14.5r15 vs 37x12.5r15 for mud? Should I go for depth or floatation? Which ones shed better?

First of all I can tell you that theres no way in hell you can fit 37's on what you have now lol. But i would say the 33's cause mud tires are all about the width. Not to sure, but the 14.5" wides would look crazy wide.

all I have to do is order 5.5 springs, no adjustment to shocks or suspension

Difference between 37's and 33 is a lot. 37's break things very easy. Even the difference between 33's and 35's is more than you think. You are running 31's now, your gears probably would barely turn them.

I have to regear anyway.

You will have to get new shocks and adjustable uppers for a SYE and a new driveshaft. If you dont already have a SYE you will need that too. Then you will need to buy the spare shafts that you will be breaking if you goto 37's unless you upgrade to a 60. Cause mud is mostly speed in deep pits. Speed + 37's = breakage. Along with extended brakelines, and shock relocators you will want either Curries J-Arm setup or long arms to get a little less angle on the control arms, for a better ride on the road. RE 5.5 springs net about 7 (so iv heard) not sure about RK 5.5 or FT 6 inch springs. 37's will need a rear disk upgrade and steering upgrade. I plan on 37's at some point in the spring. I need to do a lot of upgrades for them. Im thinking about having dynatrac build me a front 44 with hi-steer. You may not need to do all of these upgrades, But to do it right you will need to.

well the shocks I have are designed for any height RE long arm lift. As a matter of fact the whole kit is exactly like the 5.5 minus springs. I already Am SYE'd with Tom woods cv but from what I am reading I would have to have ultra stout drive train for 37's. would y'all say beyond D44s for 37's?

Oh, I probably need to spell out that "Rubicon Express Long Arm" in my signature...

I didnt see the LA at the end of your sig. Iv never seen anyone with a 5.5 with substituted 3.5 inch springs... You must have a nice ride. I also didnt know you could use the same shocks on the 3.5 as the 5.5.

The 37's are pushing the 44 IMHO. But I dont want to go full width yet, and I only want 60's in full width.

24.5/14.5 L/L 26.5/15.50 S/L Front

Same shock dimensions 3.5 through 5.5 because flex is always the same. My 3.5 nets more like 4.5 so I would anticipate the 5.5 to be closer to 7, like you sayed. So clearance is not my issue. It's a hard decision since I have to regear either way. I just don't want to be stuck doing something again because I was not pleased with the height.

[Jeepxj96]

Yea, if I was in yuor boat, I would go with 35's and regear to 4.88's and upgrade axle shafts, and be done.

so, 35 12.5 better in mud than 33 14.5's?......

[Jeepxj96]

To be honest im not sure. Some people say that you want to float on top and some people say you want to dig down.... I live in mass and there is a mix of both..i will be going with a 37X12.5R15

Go with the 35's they will be alot easier to turn in the mud than the 14.50 wide tires.
