Mods for robotic VX

[Art]

Austin Robot Technology has selected a VX as the off-road vehicle to serve as a platform for our robotic entry into the 2005 DARPA Grand Challenge. I would like to use this thread to get advice from members of this club regarding off-road matters. The race consists of 175 miles across the desert Southwest, most likely the Mojave Desert. Last DARPA Grand Challenge was held for the first time last year, the course was 142 miles from Barstow California to Primm Nevada. Most of the course consisted of unpaved rocky service roads along power lines. Some of the route went over paved roads (less than 20%). Speed is moderate (20 to 30 MPH). We will have some means of isolating the computers from shock, dust, and heat.

Let me start by asking about tires. We are considering 265-75-R16 BFG A/T KO.
An alternative is Firestone Destination M/T 265-75-R16. We want puncture resistance, we want traction. We have a conflicting desire for a "soft" ride.

Any advice on tires, comments about the above choices or other suggested tires. Any advice on tire pressure?

Thanks for any help!
