The coefficient of kinetic friction is a material property. It will be the same for a given wheel regardless of what it is connected to or loaded with.
The coefficient of static friction would also be very important to know. When the wheels are not slipping the friction is actually static, not kinetic. The coefficient of kinetic friction only comes into play after your wheels have started slipping, or when scrubbing during turns.
Many teams that make their own wheels cover them in Incline Conveyor belting from McMaster-Carr. I believe the ones that are typically used are the Gum Rubber Wedgetop, SBR Roughtop, Rubber Roughtop, and Nitrile Roughtop.
This was just in a thread around here somewhere, but I didn't find it on the first search and I should be working on a paper right now
