Re: Andymark Performance Wheels: How Were They in 2013

What wheel size were you using (4in, 6in, or 8in)?
4in

What was the speed of your robot?
Roughly 10 ft/s

Would you characterize your team's driving as slower or aggressive (higher speed, quick acceleration, turning at high speeds, intense defense)?
quick acceleration, intense defense, lots of use (3 districts/regionals, 1 district championship, 2 off-seasons - roughly 80 matches)

How did the tread hold on to the wheel overtime? Any issues with tread coming loose or shifting?
We also had to rivet our tread on due to treads coming off the rim of the wheel during high speeds and turning. We never had a failure with the zip-tie aspect of the assembly just with the treads sliding off.

Did the tread stay securely on the wheel until it needed to be replaced or did it come loose?
Once riveted it stayed on till tread replacement was necessary

If adjusting loose tread was an issue, how often?
Not an issue once tread was riveted

Did you noticed performance difference while driving in straight lines, pushing, turning, etc?
Nope

Would you use them again or make modifications to them?
Yes i think we will use them again and we will definitely be riveting the tread again.

As Scott said, the fastening of the treads is very neat, however it does not offset the effort of cutting and sanding down tread. We went through many zip-ties and pieces of tread in an attempt to get the tightest possible fit so that we would not have to rivet the tread on. All this work was useless as rivet was the easiest solution to keep the tread on.
Ultimately the wheels are great and I would recommend the hex fit to anyone, just be prepared to rivet the tread onto the wheels.
