Discussion in 'The Garage' started by DUKE, Jun 3, 2002.
I was checking out the new offcamber site (sweet btw) and was just wondering.
As far as i know its because the outer locking ring can losen and come off, or cause a rapid lose in air pressure. (if proper torque on the nuts is not maintained) Resulting in the tire coming off, or a blow out. bad news. I just bought a set of hummer stile rims because they are DOT approved and also lock both the inner and outer beads. not just the outer one..
Like most products, Beadlock wheels have a multitude of design considerations which determine the
usefulness of the finished product. We at Champion Wheel have been in this business for over 15 years and have manufactured aluminum Beadlock wheels for many applications, such as 4-wheel drives, ATV's, drag racing and off-road racing.
While tires have many pages of DOT regulations, wheels have only three. 1. The manufacture's name. 2. Date of manufacture and 3. Load rating must be specified. As you can see by this Beadlock wheels must meet DOT specifications. The usage is regulated by the manufacturer. Champion Beadlock wheels have been on the road in many different applications for more than 12 years successfully.
With Beadlock wheels you can use as low of air pressure as you want, but do not exceed the tire manufacturer's recommended pressure (usually 32 - 35 psi). It is also important not exceed the load rating of 1,500 lbs per wheel. Champion Beadlock wheels are used in off-road races such as the Baja 1000 where they are subject to rocks and potholes at speeds well over 100 MPH. Beadlocks are a must-have item to keep the tires on in these conditions.
Our Beadlock wheels center the tire with a shoulder machined on the rim to insure tire-to-rim trueness and balance. Our drag race conversions have gone well over 300 MPH withstanding over 6,000 horsepower on Top Fuel and Funny Cars.
Beadlock wheels are used in many different applications where tires have to be retained on the rims. Four wheel drive vehicles are a perfect application because of the high side load and low air pressure desired. Because of the different bead widths of tires, Champion Wheel counter bores the outer ring at a 10 degree angle so the ring will flex and be able to rotate under the bolt head when tightening. This relieves the stress on the bolt head, especially important on the thick beaded bias-ply tires.
We use 24 - 5/16" NC Grade 8 bolts which is well over designed even on our design of Beadlock. Champion Beadlock rings are cut from 5/16" 6061 T-6 Premium Aluminum that eliminates cracking or breakage. We use High Carbon Steel nut inserts on the wheel ring to further insure safety.
We manufacture all sizes from 8" diameter through 17" diameter. All 16.5's can not be Beadlocked because the tire bead has a 15 degree bead seat angle. The bead will not have enough contact on the rings to control tire movement successfully. The 16.5 tire is a high load, high pressure designed tire and the 15 degree angle bead seat is used as a taper to match the rim to relieve the stress put on the outer rim lip of these types of tires. The 16.5, 19.5, 22.5 and 24.5 are light truck to heavy tractor (diesel truck) tires with loads up to 6,000 lbs each. None of these sizes can be Beadlocked successfully.
Hopefully I have cleared up any questions you might have about the Beadlock design. Although it may have seemed that Champion Beadlocks had design flaws, IT IS CLEARLY NOT TRUE. The same design has been used for many years and in many applications without a problem. We at Champion Wheel take great pride in our design and in our quality workmanship put into every wheel we manufacture. We hope that our customers are as satisfied with our product as we are.

Wow...thanks for sharing that! Nothing like hearing it from a reliable source like that!
Why can't my post's end like that? LOL!!!!!!!!!!
ask and ye shall recieve, dang. That has to be the most informative reply to a post ever. Thanks for all the good info.
very informative, but are they dot approved or not? That is still unclear, at least to me.
Very interesting, but this part is kinda scary: <blockquote><font class="small">In reply to:</font><hr>
It is also important not exceed the load rating of 1,500 lbs per wheel.
<hr></blockquote> A stock K5 isn't far from this. Add 1-ton axles, a winch, some serious bumpers, a roll cage, high-lift jack, chains, a cooler, some camping stuff and a few spare parts and you've exceeded the load rating of the wheels. And we haven't even mentioned the load that would be added by a trailer... /forums/images/icons/shocked.gif
After reading that what would we pay for forged aluminum HUMVEE style beadlocks with the rubber beadlock/ runflat in a normal backspacing? $350.00/ $400.00 a wheel?
These guys offer a cool beadlock system that will work with just about any wheel. http://www.tireloc.com/ Last I knew, they run about $800 per set of 4. /forums/images/icons/shocked.gif
