Go to Post If we can transform our culture to the point where girls swoon over guys as they pull their dremel off their belt and carve some speed holes in a smooth fluid motion, I think FIRST is half way to its goal. When we get the guys to swoon over the girls for their hot moves on the 5-axis, we have won. - EricVanWyk [more]

I agree with you here, for wedgetop. Blue Nitrile Roughtop is among the most durable tread materials I've used. Over the 2007 and 2008 season, using the robot for both competition and demos, we NEVER changed our tread on each bot. Never had a problem with roughtop wearing. Wedgetop, on the other hand....

Nitrile rocks. Never had a bad experience with it. Just lay it against an AM wheel that's been stripped of the polyurethane, drill some holes and slap a few pop rivets in. It's janky, but it WORKS.

last years robot was two wheel drive with almost all the weight on the front two, we had great traction, but we couldent turn well, and the tread wore down to nothing after the FL. Regional!
Yeah, weight distribution is key. I've mostly used roughtop on our 6 wheels, and had no problems there. The closest we got to wearing tread out was on our 2005 Crab Drive, for Triple Play, and that wasn't bad enough for the bot to be at a disadvantage.

Seriously, if you do your attaching right, you can't go wrong with Blue Nitrile (assuming FIRST keeps the carpet....).
