35x12.50 17 on 7.5 stock wheel

[DanW]

Not trying to get nothing started because I totally agree that I haven't heard about a tire failure but also show me a spacer failure that's happened. In almost 22 yrs of using them, never heard of one. Show me a example of a hub centric spacer that's failed when properly installed and torqued to specs.

The key word is when torqued, but you have to keep checking them as often as 3k miles or you risk a potentially nasty situation. Some recommend checking them more often than that.

It took me no more than 30 seconds to find this one. And I've read of a number of others over the years. I didn't just pull that out of my ass.

I don't disagree with you that what you posted can be a problem. It just would be likely with something more extreme than being 1/2" below recommended rim width on tires and rims of this size.

For one you just got to check them when you rotate tires about every 5,000 miles and two that examples sounds pretty much like improperly torqued wheel studs, he said tightened them as much as possible which could have damaged the wheel spacer, no different than over torquing a stud on without wheel spacers. Torque specs are important, if your using spacers or not. Plus I never read or saw a picture posted. I have never seen one or read about one that didn't come down to the installing being a factor.

Bottom line, if you buy a good hub centric wheel spacer made out of billet aluminum and preferably a brand with a good name then your probably not going to have a problem. But nothing is 100%, even running wider wheels, anything can fail if not install properly. Ran them on my JKU for over 120,000 miles , on a XJ for darn near 270,000 miles and now got them on my JT for the last 36,000 miles and I haven't had one issue.

Maybe, but it took 30 seconds to find a problem directly related to spacers. I also don't feel the fun in ever 3k to 5k having to remove tires and torque torque 40 lug nuts.

But this really wasn't a discussion of the merits of spacers, which I still contend is a bad comparison, as it again took me all of a few seconds to find an example of a serious problem. I've no interest in them, at all, whether they are good or bad. So it's really moot. If a thread starts on them, I probably won't go in there even out of curiousity.

Bottom line is that nobody has shown even an anecdotal problem with 12.5" tires on 7.5" rims. They are good to go, and the experiential database is HUGE.

I agree it's a poor comparison but that post you posted was installing error not a problem with a spacer. I found this as well in under 30 seconds.

That has nothing to do with spacers. If lug nuts are over torqued or not torqued enough it could happen, spacers or not. Also if a wheel comes off what do you think will be the first thing damaged a wheel spacer when it slams against the ground, then you get the my wheel spacer failed post. That's all I'm saying, most of the time your not going to see the post where someone forgot to tighten their lug nuts because they don't want to look like a dumbass

If you don't like wheel spacers then just say I don't prefer them but don't call them unsafe just because you don't want to do what is required to make them safe. It's not hard to check them if you rotate your tires every 5,000 miles then you can have the shop check them when they rotate your tires or when you rotate your tires.

I looked at my last 2 posts and don't see where I called them unsafe, especially if maintained properly. If I did, it is an opinion. And if improperly maintained, sure, I'd call them unsafe. But that's the rub. They are maintenance intensive.

There is absolutely zero additional maintenance or worry with a 12.5" tire going on a 7.5" rim. And in nearly 3 decades of off-roading and Jeep forum browsing, I've still don't remember seeing a single case of a problem with a 12.5" tire on a 7.5" stock rim. Not one. I cannot say that about spacers.

I've run 50k on a set of 315 KO2s that are exactly the same size as the 35x12.5x17 version and am now 5k into a set of General Grabber X3's in 35x12.5x7 on stock 7.5" wide rims on my JL. No issues at all and the KO2's are sitting in my garage and probably have a good 15k left in them.

They bulge out nicely and do a good job of keeping rocks off the rims, too, when wheeling. They drive perfectly and there is no rubbing even at full articulation and full lock on the steering. (Mopar lift). They also hold the bead on the rim very well when aired down. In fact, the old fogeys like Dan Mick in Moab call big tires on narrow rims "poor man's beadlock."

My brother is also running 35" Falken MT's on his stock JT Rubi rims. He also has no issues and no rubbing and is running the JT version of the Mopar lift.

is he running spacers on the wheels?

So I guess you have saw first hand one fail, not read about it on the internet, OK if that's the case you got me.

Nope. Straight up stock Rubi wheels and Mopar 2" lift. No rubbing, runs, drips, or errors.

I've never seen a plane crash, either, and I'm a pilot and have spent my life around airplanes and airports. But I guess because I've read about that on the internet it means they don't happen.

Good to know.

You saw pictures of one that failed.Plenty of pictures with plane crash stories.

I have 285s on stock wheels. At 30k, the centers are worn notably more than the shoulders. When inflated to spec pressure, it wanders. With pressure down around 30, it tracks a little better.

You have to adjust your pressures accordingly.

Even with stock tires, the recommended 37 was too much air for driving without a load or towing anything.

Lol, honestly, I don't give a shit enough about spacers to find more for you. They don't interest me in the slightest. But at least you know the maintenance they require and can run them with no problems.
