Hello Gentleman, I am looking to buy an air driven impact wrench to remove tires from my F-350's and trailers. I do have an electric compressor. It is a Craftsman (1.1 HP) 120 PSI. Is this sufficient for doing the job as I think I need a bigger unit. Also, what size Impact wrench is needed? I am looking for the minimum that would do these jobs as this is the hardest the compressor will be working. Thanks!!
