In the case of using a pre-blurred texture-map, you might want to have a look at the FXtree and apply radial blurs and other FX to your image clip there. The reason being that, if you want to key more or less of an effect, you can easily to that, if you want to get fancy, link the blur values to something else, like the tire's rotation.
