Tyre pressures using Secondair Beadlocks - experiences

[wannaberacer]

What pressures have people used when they have the Secondair beadlocks installed?

Have you had any problems with them?

Things to avoid?

I am installing mine on 15x8 Sunraysia's with 33" BFG M/T.

Cheers

I ran my Tyres at 4PSI in the rear and 6PSI in the front and the Beadlock at 40PSI Never had a tyre come unseated. Also put a hole through the sidewall and drove about 4KLMs with the tyre dead flat. It was hardly noticable. This was Running 38TSLs.

Tony what was your opinion of the second air style beadlock compared to the mechanical ring style.

Some points to consider...
make sure all the swarf from drilling second hole in rim is cleaned up and hole is smooth
be careful not to pinch tube as it's fitted
I'm unaware of anyone else who's had problems fitting them, but mine had to go back to the fitters several times for leaks in the tubes.
Sensational product though! On my zook I run my fronts @ 3-5 psi (depending on terrain) and the rears @ zero internals i run @36 . Have never done a bead since fitting.!

I guess the Zook is quite light anyway. Does it have powersteering? Any dramas turning the wheels with so low a pressure? I don't have powersteering yet on my 4wd (MQ SWB)...so I think I'll be in for a workout until I get it fitted.

Any issues with staking the tyres on rocks/branches?

yeah I do have power steering
Was running zero all round til I worked out I could steer MUCH better with 5 in the fronts. It was spending a fair bit of time flexing the tyre and suspension at zero. I still have occasional issues with steering but i think this is related to my lockright not unlocking sometimes.

P.S. Never had a staking issue, but the boggers are pretty tough.

P.P.S Yes you will be in for a major workout! I use to get totally trowled steerin the zook around a course!

I usually run 8-10 psi in the tyres and 40 psi in the seconds. 31 x 10.5 Simex MT's with about 1800 kg all up weight.

Advantage is they protect the inside bead too, especially when you are off camber "hanging"over a crown by inside of your upper wheel.

What sort of 4by?

can anyone give me some info regarding this question

I think one of the things you need to watch is that some normal tyres, eg. BFG's etc may crack across the tread at such low pressures. You'll notice that most of these guys are running serious tyres and often bias ply.

Second Air are good for a vehicle used on road. Mechanical bead locks are illegal for onroad use.

Have never used mechanical but here's my thoughts
1. Second Airs lock both sides of the bead (before them I quite often threw an inner bead).
2. They are more discreet on-road.

Due to the extra valve hole, Second Air's are not roadworthy either. Unless you buy custom rims with two valve holes (highly unlikely).

[Old Yella]

are there any inherent problems with the second airs, like holeing them with crap getting past the bead

and also I know apart from the second airs locking both beads what other benefits do they have, like for instance a mechanical ring protecting the outer rim edge from heavy knocks......

I'd just like opinions from other peoples experiences with these and other set ups before parting with my hard earned moola

Experiences from a friend...

Valve for 2nd tube needs a flat inner surface and the 100 series rims are too narrow. I kept getting air leaks around 2nd valve and in the end had to buy 4 non Toyota rims.

The valve in the tube has come away twice from tube. Tube goes down but driver is not necessarily aware because still have air in main tire. The result is broken tube flaps around and overheats tyre. Result - 2 buggered MTRs with great slabs of molten rubber.

Suggest if you do get them only get 2 front - tyres come off at low pressure when turning and 95% of time its the front.
