Swedish Tire Lock System
I seriously want to get bead locks, but I'm a little worried about their road manners with my tires. Now my jeep doesn't spend too much time on the road, just long enough to get me to/from my trails, but that can be up to 4 hours of highway there and back. When I last mounted my 35X15.5 Swamper SXs on my steel 10 inch rims, they were real buggers to even get close to balanced, and from what I hear balancing is even more difficult with bead locks. Combine that with what I've read about bead locks potentially coming apart at speed on the road, and I'm a little worried about them on the street even though I know I need them on the trail (I'm airing down to 5 or 6 psi now, without bead locks, so far no lost beads, but GETTING WORRIED).
So I started to look for some kinda alternative, and ran across these 'swedish bead lock' things. The concept as I understand it is an inner tube which runs inside the tire that has a kevlar belt wrapped around it so that when it is pumped up with air it can only expand laterally against the beads. This forces the beads against the rim, in effect locking them against the rim. The supposed benefits are that you can install them in any rim (just hafta drill 'nuther hole for the inner tubes valve stem), and they provided run flat type service, and you don't need to pump in so much air to air up! Also, this system locks BOTH beads, not just the outside one.
Down side as I can see/guess is that you might have problems getting the valve stem to seal, meaning you might end up with a slow leak in your tire, I've heard of chafing problems causing the inner tube to puncture, and although this might force the bead out, it doesn't prevent the tire from spinning on the rim, although I guess a regular bead lock doesn't do that either, does it?
I am hoping that there are some people on this list who have opinions and most of all experience with this system:
1) Does it have less effect on balancing the tire than a regular bead lock?
2) does it work as well as a regular bead lock for locking the bead?
3) Is it reliable, or is inner tube puncturing going to be a problem?
4) Will it seal properly?
5) Does it make mounting the tire so difficult that my regular tire jockey won't be able to do it?
The system is quite expensive - $800us or so for my size rims - but it might be worth the extra cash if it is safer on the street, locks both beads, allows easier balancing of the tire (than regular bead locks), and makes it easier/faster for me to air up.
Please let me know what you guys think.
