So this is not a black? Or a different sticky compound? DOT or no?
Do you worry about breaking parts when running water?
This is not a black....the sticky version is coming in 2022. It IS a DOT. This carcass/rubber combo is the same as what is on my FZJ80 in a 315-70-17.

I never ran water in my old FToy, the axles and drivetrain would not hold up....but no worries with the current setup. Plenty strong for that added weight/traction.

Ugh....why does noone make a 42 for 17" wheels besides maxxis and Interco....
42's for a 17" wheel will be coming in 2022.

Personally, I feel there is too much sidewall with a 17" wheel and the 42. Far better trail handling/control with the 42/20 combo. But, that added expense of new wheels isn't fun either.

Working to feather the tires....coming along nicely 😎

Also decided to bump water to top of wheel...

However, they worked perfectly today....made one line I have never cleared and a few others with much less effort and wheelspin.

And, we have lights!

Cleaned up the switch panel, and am finally happy with the whole dash layout. 6 rock lights installed, one 6LED bar, and a small amber rear facing light should arrive today. Haven't done a night run yet, but they look good in the shop...lol

Rock lights (I won these at an event)
Amazon product
LED switches: (BTW, the yellow is useless and can't be seen in sunlight...)
Amazon product
And, because the switches use smaller spades, you'll need these:



Originally, yellow for the front line lock, green for the light bar, and blue for the rock lights....but when you can't see yellow in bright sun and you accidentally switch it on and you smoke your front brakes....I switched the line lock to red. Pic below is from the drivers headrest.

6LED flood bar below the winch plate. Have had it on for a week and it hasn't been hit yet ;)

Two down-facing rock lights just aft of the rear bumper bar, two tucked in by the upper link chassis-side mount.

And the final two rock lights by the rear chassis side link mount.

So are you saying the DOT compound works as well as a sticky out there? I have to say I was impressed by the DOT milestars ability to hold a sidewall onto the face of a side hill out there. Although I was also impressed at how well my iroks were doing.

Is that James Treacy's new rig? You guys should do a feature on that one. Work of art!

It is the new JT rig, and it's already sold....so James was being nice ;)

The DOT versus Black Milestar is marginally different....not night/day like a red/blue label BFG. Two days of wheeling have surprised me, will be back out on Saturday (today was too windy). Never enough test time ;)

Did a few trails today....breezed thru Arrowhead in about 10 minutes (rated 10....barely) and then jumped onto a newer trail called Shotgun. The final climb (no pic) has only been completed by a handful of rigs thus far, and both John and I cleared it with little issue. Tough since the bottom forces you to slip one way or the other, and keeping the rear in JUST the right spot is tough...plus, a touch of momentum is needed.

End of day tire pressures in the rear was 9.5!! Dropped about a pound or so all around, so we'll see how they perform next time. Did clear a few climbs today that have denied me in the past.

Ironman, Stage1 - complete :)

This was my view Sunday afternoon....we had already run Sandthrax (10) and DeKleined (10) and the buggy successfully ran all but the signature DeKleined crack....I was SO close, but just didn't quite figure it out. Hopefully when the tires are burned in a bit more.

Our fearless leader decided running TrailBreaker Year 1, Stage 1 (now Ironman) was a good idea...I wasn't so sure, but there is no time like the present to learn and push. The crack in the pic was easy, the BIG climb took a bit to find the line and the time the launch correctly, and the next crack about ate me up...but I completed it, and learned a ton about angles and tire placement. The tires performed.

This pic was taken at the top of the SnakePit climb on DeKleined...its slick and sketchy and took a bit...but the tires are feathering in nicely :) YES, these are the DOT compound tires, NOT the stick/black labels. Andrew called me this morning after he saw the pic, FULL of questions...he was pleased with my report, and I'm quite pleased with the tires performance.

I didn't even try the sig DeKleined with no rear steer but had fun on the rest of the trail. Was tempted to try the snakepit but was running SX stickies so I chickened out. That other stuff is out of my league.
Rig looks awesome. I've seen some pics of your rig posted on Irate4x4 too. They all look good. :)

Today, air shock tweaks...

Glenn with Radflo told me to run these "as is" for a while to be sure they needed adjusting. Honestly, he was about right. They worked well, had "ok" oil fill and allowed the nitrogen pressure to stay low. With 2.5-3" of shock shaft showing (depending on temps), I was 65# front and 50# rear.

The easy adjustment for air shocks is oil. I added 10cc to each rear, installed the valve core and didn't add any nitrogen...then "dropped" the rear with the engine hoist. The shocks stopped with about 1/4" of shaft showing, which is perfect. 30# nitrogen left 2" of shock shaft (competition height) and 50# of nitrogen set shock shaft at 3.75", which is about perfect for trail height. (shop temp 60 degrees, cause that DOES matter) Things are likely to settle after a run/two, so pressures may change (as they will with outside air temps).


Per Radflo, their 16" 2.5 air shocks ship with 700ml of oil. No wonder they were near perfect from the get go!
