I agree, they won't last 2 years. After just 2 competitions, our wheels are starting to look rough, and all the rivets are well worn down. We aren't going to change them for IRI, but we will be bringing along spares! We have a small chunk missing off of one of the wheels... I wonder how that happened?

On Topic:
We did order our blue nitrile from McMaster. We ordered a very large sheet for spares, maybe too much. We had a complete redesign for wheels this year trying to lose some weight. We experimented with IFI wheels and with the AM Performance wheels (which are 1"). We ended up not liking the IFI wheels due to their screw it together style, and a small gap for the CIM motors to cool. We ended up using our trial IFI wheel for our grabber.
