33x13.5 Rockers vs. 34x10.5 ltb

[FJess]

I'm on the fence between these two. I've read plenty about the LTBs and larger Rockers, but haven't found too much info on the smaller PBs. Anyone have any experience with these (smaller Rocker) or want to make a comparison? Looking mostly for performance in rocks/dirt (Colorado wheeling).

Whatever I get is going on a 17x8.5 TR beadlock...open to other suggestions as well.

13.5" Pitbull is going to be pretty wide on an FJC. What BS are you running on your wheels? That wide of a tire might cause some interference/clearance issues on your UCA and elsewhere.

THere is alot to be said about getting a bigger footprint on the ground but if you are going to do much in the rocks you will want a minimum of a 35. I think the BFG's are 35x12.5.This would require a 3" lift and a slight body mount chop.BEad locks are great if you are going to really air down and use them but other than in the sand I cant imagine what you would be doing with a 33" tire that would require that. You really need to take your rig out on a trail that you want to be able to do when you are done and see what kind of issues you encounter( make sure you have a winch) this will tell you what size tire you need.

Sorry...didn't mean for this to go in a "will these tires rub" direction. Pretty well versed on that.

Mad dog - would you prefer a KM2 to the LTB? KM2s were also on my radar, but pretty well documented so I didn't ask about them. Not so worried about DD performance, for what it's worth. I was originally leaning toward those in a 35x12.5 but have been leaning toward the 34x10.5 LTBs lately.

Might clear then. KM2s tend to run undersized a bit fwiw, still will rub, just not a true 35" tire...probably pretty comparable height wise the the LTBs.

Steering with the wider pitbulls is going to be a bit different than the LTBs due to the additional width.

Jess, FWIW
2 years ago I ran the KM2 in 285 on the black trails at Rausch, did ok. Had to pull cable a couple times. Then last year I went back with 34 X 10.5 LTB's
(only because the 35x10.5 ssr was out of stock)
The LTB hooks up real nice and at times was almost folded over on itself @ 12psi. Yes a larger foot print is better, but as you know the FJC has limits.

Keep rockn , hope to meet ya out there some day.


fully skid'd, tummy tuck, lefty, for reference.

I do not have expierience with LTBs but I have run 35" and 40" KM2s and had very good luck with them. They do hook up real good in the rocks and they perform well and are pretty quiet on the road for an open patern. I think that they are a good all around tire for a variety of wheeling. and I think that the 35 being a little under sized is a good match with the FJ.
Having said that I am looking into some Good year MTRs but mostly for the sticky rubber for rocks and do not plan on using them on the road.

Ordered some 35x12.50 MT/Rs today.

It's hell trying to figure out what shoes to wear, isn't it?

For the record, same size tire on same wheel measures 34" at the crown and less at the outer edge.

They are undersized, in comparison to any other I've actually measured, installed, but I've had good luck with mine, so far. After destroying the previous tires on two trips through the sharded rocks of Superlift, KM2s pulled through with no chunking.

Said elsewhere, but for the record, I put 8.46 ounces of airsofts in each (2000 qty, can't recall diameter) and will be adding to, just because.

Supposedly, you can't add too many, so I will increase the initial quantity by 50% on the next go round, and mostly an effort to eliminate the higher speed vibrations, which you may not find unpleasant. :thefinger:

Shoe shopping is fun...tire shopping, not so much.

Given the FJC's limited wheel well space, I'm kind of counting on the MT/Rs running a little small to give me some breathing room. I think I'll go with 12 ounces of pellets, even though the high-speed vibration is intriguing.

Pics (or video) or it didn't happen!

Hahaha.

[Mad Dog 1]

I dont get the whole pellet thing. I mean I understand what they are but I'm not sure how they effec offroading performance. Dont they add some kind of unsprung wieght?

[FJLED]

Its 12 ounces (unsprung), they aren't going to add anything to offroad performance (nor take anything away). Main purpose is for balancing the tire vs. conventional wheel weights.

Forget the pellets...They dont work as well due to the ridges in the tire. Use golf balls and tennis balls- they work better. Ya might also consider a small amount of anti freeze too to cut down on the freezing of those pellets in the cold. Just enough to keep the bunch from staying bunched up.

High speed vibration....

Any videos yet?

Nope. Unnamed vendor still dragging their feet getting my wheel problem sorted out.

[FJess]

Heard from Larry at TR today - he's sending me RimRock Mtn. rapid air down valves vs. the monster valves. Was kind of hoping for the monster valves, but he claims these are better. Thoughts?

Hoping to finally have this all sorted out by the middle of next week so I can get the new tires on before a trail run the weekend after this. My current tires are beyond done and I won't run again on them unless I'm forced to.

[FJess]

New wheels/tires installed. Very happy with the way everything turned out!

^^. You posted a driveway pic?^^

Are you feeling ok?

[FJess]

Sorry - is this better?
