In 2006, DeVilbiss recalled nearly 700,000 pressure washers and air compressors to replace the pneumatic tires, which were sometimes bursting on models that used plastic rims. Apparently not enough consumers responded then, because the complaints keep rolling in, so they've announced a do-over.

If you own a DeVilbiss pressure washer or air compressor with solid tires or steel hubs, you're fine. If you have pneumatic tires, however, check out the model numbers included in the recall and contact DeVilbiss at 866-323-9867. They'll replace the hubs and tires for free.
