Thank you Swordy... I found PJ DirtGrip here:

http://www.ntwonline.com/acb/showdet...unt=1&DETAIL=1

This seems to be the tire for us:

PJ-31x10.5R16 (10 ply)
Load Range: "E"
Section Width: 10.3
Tread Width: 8.8
Rim Width: 7-9
Outside Diameter: 31.50

This one is bigger, would it fit ????

PJ-33x12.5R16
Load Range: "E"
Section Width: 12.4
Tread Width: 10.4
Rim Width: 8.5-11
Outside Diameter: 33.30

Here's a picture of our front right wheel.

Thanks for everyone's help!

Thanks for the heads up... I looked into it and found we were running low on our disk quota on the website host. No need to resend, info@austinrobot.com forwarded to another account (on a different host) and we did get your logo. Thanks!

No, THANK YOU and good luck!!!

Art,
No, 33/12.50-16's will not fit without a lift AND fender trimming. I think you should be safe running 31's without problems. Its been a while since I ran tires that small, so you might want to refer to a couple of the many tire size articles on the site. The subject has come up fairly often.

Art, just outta curiosity. I haven't throughly browsed thru your website. But are you guys using solid state drives on your setup?

I agree with alaska about mickey thompsons. 30" baja belteds rocks and would look good too- something about tread on the side of your VX tires just rules. Art, when you guys have a finished product, you're gonna make it a package for all of us to buy, right? I doubt I am the only one that wants an automated or remote controlled VX.

For now we are using disk drives... may go solid state later.

Here's my current thoughts on tires, I like the Parnelli Jones because of the "E" load rating (thicker sidewalls to protect against rocks). Use STAUN internal bead locks at 48 lbs and run the tires at 25 lbs pressure. Use
TXT PRO tire sealant to plug punctures.

We have no plans to use 4 LO at this time, our plan is to let TOD do it's thing. We might decide to use 4 LO after testing.

Good points on the compatibility of the tire sealant and bead locks, I've sent an enquiry to both companies.

Good point on tire pressure, we need to test this.

Regarding when we will test this in the desert, that depends on whether we are selected as one of the 40 teams that go to the qualifying event in September.
We are currently testing in private ranches in Central Texas. Provided all goes well and we advance to the next round, we will be doing longer test runs in canyons in west Texas during the summer months and in California in September; the race is October 8.
