Well I guess it's past time for an update, have had more disappointment but I think things are looking up.
My first tire experiment went horribly wrong and pretty much can be sumarized by flushing $100 down the toilet. I cut every other section of the middle lugs out of the rok loks and replaced the stock foam with panther memory foam. I had a comp on the 7th of March. That turned out to be pretty ugly. The tires just don't have the grip they need. I got in trouble several times because the tires slid sideways off of stuff because of lack of grip and also once they just got stuck uder a ledge because they were too tall for the necessary line. Basically to compete with people running Nova Plowboys you need something better.
So after the comp I tried to contact Novasark and didn't get any reply. I didn't order tires because I wanted to make sure I was getting what I wanted before sending the money. At any rate after thinking about it a while I decided to give it one last shot at making something.
I was going to try putting a rover on a 4" wheel. Fortunately I couldn't get white compound rovers and I looked around and saw Turbofests Sedonas (Thanks Turbofest) so I decided to go with the Sedonas. I had never actually seen one but read they were a little wider than the rovers so I figured it might work with my existing wheel. Not modifying a wheel was something really important to me.
I ordered 4 sets of Sedona's from RPP and they shipped the same day, that's pretty cool. The downside is I ordered them on Monday so I decided to go with the post office priority mail. So 8 days later in a crushed box with a sticker saying it was damaged before it got to the local post office I finally got the tires. Nice work uncle sam "thumbsup", maybe next time you can at least keep the donkey from trampling it.
So below is what I finally came up with.
My Sedona 4.0
I already had a set of the Axial oversized narrow beadlocks (AX8071) so I decided I was going to try and make them fit somehow. I did a bunch of drawings in the computer working with the circumfrences trying to come up with a cut and shut pattern that would make the tire the rite size. After coming up with a buch of options I didn't even want to try. Most had at least 8 glue seams I decided to just wait for the tires and play with them a little first.
So I opened up the package and cut one tire then started aligning it with the wheel. I immediately noticed the triangle shaped groove in the beadlock didn't fit the tire with the way the bead and the sidewall reinforcing were designed. However; after a few seconds of extreme disappointment I realized that the sidewall reinforcing would make a great bead with these wheels, and make the inner tire diameter closer to the 3.8" wheel bead. So here with a little extra information about what I know about glueing tires is what I came up with.
First In order to make the tread not be all crumpled up. I calculated the outside circumfrence of the existing 2.2 tire and the desired finished 4.0 tire. Then I used a percentage to determine I needed 1 full tire and 108 degrees of another tire to make the correct tread circumfrence. I used a machinists protractor to find where 108 degrees is. Fortunately for people that think they might want to do this it works out to 5 full side lugs is just about perfect. So I cut a five side lug section for my second piece.
Next I trimmed the bead as discussed above. Sorry about the blurry pictures but on the left you can see the C shaped bead sidewall reinforcing. On the right the bead has been removed so there is just the sidewall reinforcing.
Here you can see how the sidewall reinforcing fits into the groove in the axial beadlocks.
At that point I went to glueing together a tire. I haven't seen this elsewhere on the site, I expect it's here somewhere. At any rate here's a couple tips when it comes to glueing tires.
First thing you need IMO is a lot of alchohol, (at least a 6 pack, j/k), seriously though Isopropyl rubbing alchohol works great for cleaning the ends of the tire where you're going to put the glue.
Second thin super glue (I prefer the Super Jet) used sparingly is key. Put just enough glue on the tire to make it look wet and glue about 1/4" at a time starting on one side. Cyanocrylate bonds by forming a 1 molecule thick layer chemically bonding to each surface. It doesn't work by drying; more is definately not better when using this stuff. If you get the right amount of glue on the tire it'll bond the 2 sides about as fast as it glues your fingers together.
Third have some zip kicker around hopefully you wont need it but if you get an area that just wont seem to glue you can put on a little extra glue and hit it with a squirt of zip kicker for instant results it leaves an ugle white residue but works.
Forth I use a piece of a lightweight 27" bicycle inner tube to glue on the inside to reinforce the seam. This probably isn't necessary but it doesn't hurt anything.
On other note, on each tire when I was glueing the second seam it didn't look like it was going to work rite, but after glueing it together, the tire had a pretty good shape to it.
After the tires were assembled you can see below it sits in the beadlock without any added support. The inside diameter of the glued tire is a about 1/4" smaller than the wheel, which makes for a really nice fit when it's stretched into the groove.
One word of caution: This places a lot of rubber between the beadlock ring and the plastic wheel. If you try to crank one screw all the way down by itself it'll strip the hole in the wheel for sure. I put all of the screws in and gradually tightened them going around in a circle till I was happy with them. They will go very close to completely flat against the wheel.
Here's a comparison picture to the 2.2 size tire. On the wheel the tire is 2.65" wide with a 6 3/4" outside diameter. I used the stock foam. Actually used 8 of the stock foams to make the foams for these. I ordered some Novasark foams to give a shot when they get here.
And a couple pictures on the truck.
