Jack Straw Looks like the toyos are not significantly heavier than the usual suspects in a 31ish size (looking at stock tj rubicon size). Looks like they could be a good option there.

My friends with JK's would not agree with this statement. Three different R&P failures with their JK D30's on 3 different Jeeps.


JK D30 Ring and Pinion sets typically break because a u-joint gives up while under a load. The resultant shock load travels back through the axle shaft, which has become a torsion spring and strips the teeth off of the gears. Pretty common knowledge.

They think that the JK's built in traction control somehow exacerbates the problem by applying braking force to try and slow down a spinning wheel. . .that can break the u-joint and start the chain of events outlined above. JK Axles are also wider and probably have more flex issues than any of the older housings. None of that helps.

All that being said, I have ran through 2 sets of Toyo 33x12.5x15 tires on my Jeep before I went to 35's. Yep, they are heavy, but performed well, and I had no complaints at the time.
The 35x12.5x15 Procomp Xtreme Mt's I have now, weigh less than the 33" Toyos. I can tell a huge difference in braking performance when I went to the lighter tires, even though they are larger. I also went with alloy wheels and sold the heavier steelies.
15lbs of extra weight at each wheel is a lot of rolling resistance. IMO, I would go with a different tire.

Hmm, I suppose you're right. I wonder how hard he wheels...Johnson Valley for me so plenty of tough trails and lots of rocks.

Off road they are just as good if not better than the cooper's or BFG's I've ran for years. And very quiet on the road.

To each their own.

Yeah, and the new style MTR/K is also somewhere in the mid 60's. I was just curious to know how large of an impact the extra weight would have. Looks like quite a bit. With chromoly shafts I know my u-joints are the next weakest link on the trail but I'd rather have them break than put in sturdier ones and shred my r&p. Looks like I'll lean more towards the lighter tire options to minimize risk.

darkproximity I would worry about more than just your u-joints, you're also going to be putting additional stress on other axle components such as ball joints, and your unit bearings. If you're okay with having to replace those more frequently then go for it, but since you're already pushing big tires on a 1/4 ton axle, I would err on the side of caution and try to use the lightest tire possible, as to reduce the chance of breakage and premature wear. You also need to take into consideration your brakes, more rotating mass is harder to stop, heavier tire will be harder to stop.
Everyone wants to play the 35" tire game, but not everyone wants to pay the 35"+ tire price.

5spdftw Hmm, some nice input here but still no word on if the fatty 35/13.5 Toyo's with turn my locked D30's u-joints to jelly. Any experience with this size on a similar rig?

Probably because they can't afford tires so they get them on credit from Les Schwabs and that's all they really carry for mud terrains lol

Moabrubi Toyos are really heavy, But I run Cooper STT which is basically the same thing as the toyo and love them in the rocks. I think next time I want to try the MTR/K seeing how everyone raves about them. But I can't see them being much better than my STT's.

sm31 I think Rocky's response was in reference to the previous posts... which also neglected to address your question. But in Rocky' defense, at least he has first hand experience, unlike the rest of us.

I understand how tough they are but my original question was not, "Which tire is better?", it was, "Can my locked D30 handle a couple of 80 lb 35/13.5/15 Toyo's?" You have less of a problem with 33's.

Very true, plus an added bonus is the huge price difference. It seems everyone either hates them or loves them. I'll probably end up picking up a set of the new MTR's. Anyone else care to weigh in?

Toyo MT's too heavy?

Hey guys,
I'm about ready to consider getting a new set of tires on my TJ. I have 35/12.5/15 old style MTR's now and I was looking into the Toyo MT's. However, they only come in a 35/13.5/15 and they are about 15 lbs heavier per tire than the MTR's. I'm on a locked D30 with chromoly shafts, would it be able to handle the extra size and weight of the Toyo's or would I be pushing my luck too far? For what it's worth, I like to play in the rocks and its mainly a weekend rig. Thanks for any help guys.
