These are the brand new tires and wheels I got for my wife's bike. I'm excited to get them on. I already have some tire irons and a pump, so I should be good to go. I was able to get the old tire and tube off the front wheel and, with some fumbling, get the new ones on. When I went to put the front tire back on, there was some issue as to how to position what looks like a toothed washer, but I think I got it right, with the tooth in the hole.
When I went to get the rear wheel off, I found that the nut was on too tight. (The bike has been sitting for several years.) I leveraged all my weight against it and had gloves on my hands to protect them, but still couldn't get the nut off. My next step is to invest in a better wrench or at least some WD-40.
