Mods for robotic VX

[Tone]

Welcome and good luck! Bob Land Racing did Laughlin and a number of other notable offroad events - not sure if his site is still around but you may wish to search the web or this site. Cyrk, you have the autographed picture with stats on it - see what he lists for tires.

I'd think you'd most importantly want to use tires that competitors had used in Baja or Dakar or any of the other big events.

I'm not positive on what the conditions of the desert are but if it's deep sand the Mickey Thompson Baja belted tires did well here. I would not do a standard MT style tire (Like BFG MT) in the sand as it will dig in too much. You would want the widest tires possible too to keep you floating on top of the sand. For me the 31x11.5 Mickey T. Baja belted did very well in glacier silt and deep sand. No lift required just a little bit of trimming up front of the front wheel wells. The Baja Claws mounted backwards might do real well too.

But if a MT tire will work I can't believe how well my TrXus MT's do in all the conditions I have put them through. Not sure if they make ones that will fit, but most likely they do.

All the above tires give a descent ride.

Personally, I'd find a hard-ish compound all-terrain (AT) tire, or get some kind of run-flat insert to put in an AT tire. (maybe have new centers welded into H1 runflat rims) There's obviously no way to change a flat out there. If I was running normal AT tires at 20-30mph I'm not sure that I'd want less than 20psi, probably around 25-30psi. You risk popping them the higher the PSI, but you risk rolling it off of the bead at lower pressures.

I have a few pics of Bob Land's VX, and the tires that he used. They were not off-the-shelf tires. Bob told us that he had them custom cut, and were a very hard rubber compound. The ones on the VX in the pics below have a race on them, and I had a hard time telling them from the brand new ones in his shop.

You can see the size here: (7.50 R 16 it looks like to me)

Here's the tread that he ran on his Amigo:

A group from Florida entered a 1993 Trooper last year.

I saw this and the other post inthe intro forum.. First, WELCOME!! The project sounds very cool. I even watched the last one when it was presented to TechTV.
If you would like, I can made a specific forum to keep all of your updates and questions in one place so it doesn't get spread out. Let me know.

That sounds like a good idea. Thank you!

There ya go!

No advice except....GOOD LUCK!....because as far as I know, no robot has completed the trip (have they??) if not that would be really cool for the VX robot to make history. not to mention the fame would increase it's popularity and there by increase it's value. Good luck indeed. Please don't forget to post pics of that ...Desert-Storm Trooper.

gl.....keep us posted on how it turns out
