Steel wheel runout and mud tire wear

All:

I'm currently running disco steelies on my 110 SW. Last time I was at the auto skills center I had the wheels balanced. The tech said that the wheels had a lot of runout, but he did the best he could balance them. Right now they look like they have a pound of weights each.

So now I've finally got some new KM2s on the way and will be mounting them in a month when I get home. I've done more reading about runout, and the web consensus is that it 'can' cause uneven tire wear or additional wear on steering/suspension components.

Does this apply to biggish (255) KM2s... and beefy LR suspensions and steering components? A lot of what is out there on the web is about average passenger vehicles. I know some folks say not to even bother trying to balance mud tires.

Thoughts? Is it worth it to get new wheels for my new tires? Keep running the ole' cheap steelies?

You have to make sure they are balanced from the stud holes. Most places only cone balance from the centers and the centers are not machined on the steel wheels. You need to find a place that can balance from the stud holes or bring along a spare hub for them to use with the cone holder.

Interesting! Didn't think about that factor. Thanks

Any reason not to go alloy? I used to be a big believer (and fan aesthetically) of steelies but have been happy with alloys for weight savings-nevermind that we did actually crack one catastrophically during VOT.

What I've noticed with my 255/85's is right out of the box on some decent alloys they balanced fine; which was good b/c the Ft Myer Auto Hobby Shop said they were too big to balance on their machine. Maybe Bragg has better equipment.

Beyond looks and off road durability, alloys do not fit onto the older Defenders without spacers or modifications to the wheels.

Ah, didn't realize the fitment issues. Looks matter, durability I've found to be exceptionally relative for most applications.

BAHAHAHAHAHHA. You're funny.


Really though, I agree Alloys would be lighter and would balance better. For me its a matter of keeping the vehicle simple and 'no frills'. Plus, one day I'd like to be able to do events like VOT (2014 maybe?) and not worry about wheel failure. From the pictures though it looks like I'll shred 4 tire sidewalls before I crack a wheel.

For VOT run 255's on steelies (so you can beat them back into shape if need be) and carry two spares + tire kit with extra plugs...

It's a blast

I tried to have a set of black steelies balanced using the stud holes but could never find a shop in Florida that had the adapter for the 5x6.5 bolt pattern.

Yes. my 1st post referenced mine at VOT after a rock in a water crossing cracked it. Prior to that I had the same view; we're not in Africa-its not likely to happen. It still isn't...but it definitely can. I still run alloys mind you.

I've read the Deep Dish wheels had failures on Discos at Camel Trophy:

http://www.valmueller.net/camel-trop...g-information/

My D1 had tornadoes and I couldn't get them to fail no matter how hard I tried.

Of course I wasn't trying as hard as the Camel Trophy drivers.

Definitely two spares. I found out quickly that 255/85s are not a common size around southern Vermont(or northern)

Best to pick up a used hub from someone.

I have 315/75/16 BFG KM2's on stock Deep Dish Alloys. No weights. I used 8oz of the premium one piece AirSoft pellets in each tire. They purr like a kitten going down the road and no vibes.

For the sake of the VOT component, and the amusement at seeing it again:

Truth. Could be worse, Roudy had a hell of a time getting the Excursion road worthy to come back to VA.

What I am talking about is called a flange plate adaptor that goes on a balancing machine so the tire can be balanced using the stud holes rather than the center hole. I could not find a shop that had one that would fit the Defender bolt pattern. http://www.haweka.com/en/index.php?nav=5.79.83.103

I know. What I'm saying is if you get a used hub they can put it into any normal balancer and bolt the wheel on. This works well and you can go anywhere.
