^^not too specific, but any opportunity for bill nye
I would think softness has more give so it's able to counter shittier road conditions while maintaining speed, as opposed to locking in to the bumps more. I would also think that due to them being softer they'd be more prone to chunking on shitty roads.
I would then think that harder wheels having less give would get slowed down by shittier roads as they don't as readily absorb the bumps, but instead hit them harder and thus get slowed down by them. I would also think they would be less likely to chunk in this scenario due to being a tougher material. This then leads me to believe that they would be faster on smooth road/cement pavement because they have less friction with the ground.
anyone? anyone?
