I do my own, but I do my own car,truck,trailer also, personally Its easier and faster for me to do them, If you have never done a tire before it could be challenging but you gotta start somewhere. really getting them off is the hard part. careful with you new ones but you should get the idea gettin old ones off. just get ya a small pry bar and work your way around the tire first time around wont do much but its comin. It'l take a lil balls but just dont get over anxious. If your like me the garage is home anyway take you time work around the tire till its starts to come off the bead your home free from there. when putting new ones on dishsoap is your buddy, lather that dude up then get ya a ratchet strap around that booger tighten it up a bit and shoot her with a lil air, if it dos'nt seat bounce it a bit or give it the mallet treatment. If you never done a tire it will take a bit but should be good for ya
