We noticed the same. It was our first year using wheels with tread on them and the rough top SBR material gripped too much on the outer wheels and caused handling problems when turning, so we ended up replacing them with the harder nitrile rough top and life was much better. See attached pics...

So what is this urethane material Andy refers to? Is it the neoprene that McMaster sells?

Another question that has come up lately is why many teams are favoring the wider wheels - is it too reduce wear?
