Been out for a couple days so I didn't see this post. Sorry for any delays. I have messed around with adding a ring to the kit to keep the "coning" effect under control. Problem is the thickness of the rubber isn't consistant from one tire to another. I measure 4 tires and had 4 different thicknesses. So from a manufacturing stand point I can't seem to find a solution that will fix it for everybody. Basically its a cosmetic problem. As Matt said he tested them pretty thouroughly and I don't think it will ever be a problem. I have several customers in this area that have been running them for some time as well and haven't had any troubles. One of them was running an unreliable on board air source and of course it gave up after partially reinflating one tire so he drove the 30 some miles home aired down.
As to the 1.5" bolts not being long enough, your the first I've heard run into this. Just another example of the bead thicknesses varying from tire to tire. I have 44" swampers and am using 1.25" bolts and they just catch the nyloc. They are a touch short so I recommend 1.5" to everybody. My tires have the thickes bead that I measured.
Its always something. :banghead:
Let me know if I can help any. And I wanted to add, if you do decide to try a wider rim, if your careful, it is possible to remove the weld ring from the rim. I've done it once. It took some time but it is possible. You basically need to remove as much weld with a grinder laid flat on the weld. Once you get there, use a thin wheel to split the two.
