    I heard the size was originally meant for trucks that saw a lot of use in remote areas (back in the day) No safety lip made it very easy to mount and dismount tires by hand...

    I think it's like the narrower rear axle. Who knows. People did a lot of drugs back then.

    Which quickly became necessary when they found their way off the rim all by themself. /forums/images/graemlins/rotfl.gif /forums/images/graemlins/rotfl.gif

    Nah, they only lose a bead easy if they are run at low pressures. A lot of 16.5 tires are run at 45-80 psi...

    Ever since I saw my friend lose a 38" TSL at 25 PSI I have been turned off to off road tires in 16.5". Other run them with sucess, no clue how that one managed to come off, but he was just spinning in the mud and it slipped right off. /forums/images/graemlins/rotfl.gif /forums/images/graemlins/thumb.gif

    Factory steel Chevy rims DO have a safety bead. I am looking for a set to put some beadlocks on.

    I was under the impression that none of the 16.5ers had safety beads. But why does it matter if you are putting bead locks on them anyway?

    When you find a set of these mythical beasts, please share pics with us. /forums/images/graemlins/wink.gif I've read that safety beads can't be used on 16.5's because the bead of 16.5 inch tires is not shaped to mount properly if the safety bead were on the rim.

    We use 16.5s on our 3 company trucks. But as rene said they are running about 75 PSI. Never had one come off the rim and I have hauled some serious weight with these trucks. It seems to me they were not designed to be run low presure.

    I'll snap a pic of the 16.5x6.75" stock steel rims I have. They do have a small safety lip unlike the aftermarket rims...

    Re: We all know know about no safety beads on 16.5\"ers but...

    I had allway thought about putting a big long beed of weld all the way around the wheel(inplace of a saftey beed), then putting it on on of the huge lathes at school and turning the beed(of weld) down to make it all uiform thicknes and stuff /forums/images/graemlins/thinking.gif

    Because the beadlock only goes on the outside. If you run beadlocked non chevy 16.5's you still run the risk of blowing off the inner bead (which isn't as easy to set on the truck). Starting with a 7" wide rim will get me into that 8 to 9" wide range that I am looking for with a bead lock holding on a fat TSL bead.

    Lack of safety beads isn't the only problem with 16.5s. The bead surface also has a greater angle. I remember reading a safety bulletin in a tire store about the differance between 16s and 16.5s, I not sure, but I think 15,16,and 17s have a 10 degree angle while 16.5 have a 15 to 20 degree angle.

    If you ever mounted a 16.5 you'd throughly understand that. They don't even really pop when you mount them, they just kinda slide onto the seat. Mount a 15 or 16 or 17 and you'll hear a distinct pop.

    I had mounted 16.5 before and they are a pain. The easist way is to have a air hose ready with a can of starting fluid and matches. /forums/images/graemlins/eek.gif

    Re: We all know know about no safety beads on 16.5\"ers but...

    Safety bead or not. The design of the 16.5 had two main purposes. To push the bead bundle to the edge of the wheel, and to ease in mounting on utility trucks (farms, rural USA, ect). There are some wheels with a lip on them, of sorts. This will hardly keep a tire on the wheel. I work for a large tire company and almost every 16.5 we get we can kick the bead off with a good boot. (The rusted ones are a little tempermental). This is why it is not called bead rentention or a safety bead. You could weld a safety bead (not recomended though) for more bead retention, but the heavy taper will still let the bead bundle move in. If you go to a real skinny wheel (6.5 or 7) and a good size tire (38" - 42") you can make it work. It is all in how much you want to work. You can work a little harder on the trail to keep your normal 16.5's full of air, or you can put in a couple extra hours a week at the job paying off those new beadlocks /forums/images/graemlins/grin.gif It is up to the owner's driving style to decide usually.
