The bearings in the wheels of your vehicle are pretty sturdy things that have a very vital job to perform as you drive that vehicle. First of all, they keep the wheels turning smoothly. This seems like a hard thing to understand. But suffice it to say that they allow the wheel to turn without as much effort being expended on it by the vehicle. This probably has some sort of extremely complex explanation that only makes sense if you understand physics or something, but that is one of their most important jobs. The other job that the bearings in Minnesota do for your wheels is that they help support the weight of the car somehow.
