First time fitting inner tubes on wheels of this size, although I have previously fitted tires on 15" rims and larger rims. Pry bars and large flat head screwdrivers. This requires understanding how the tires fit on the rim, and you can't just force it. If you haven't already, watch some YouTube videos to get an idea of where and where to place the hoop. If you are careful, patient, and even a little mechanically inclined, you can install them. I installed one on a wheel that I removed from the mower. I installed another one on the wheel that was still on the mower. Install it on the mower with a wheel as it is one less thing to move. With these tubes I figured there would be some lubrication between tube and tire and maybe even prevent a later puncture. I've spent about 6 full days riding mulch patches and dragging rakes on these tires since installing the inner tubes and they hold air really well. No lawn, lots of rough terrain, lots of bushes, sticks and rocks, lots of unwanted burnouts, no problem. I use about 8psi for best grip. I'm very glad I salvaged some old solid tread tires from a landfill and also saved money and learned a few things along the way. For those looking, I installed them on a Husqvarna YTHK1542XPC aka YTH1542XP aka YTH 1542XP which was actually made circa 2004 by AYP and also sold as a Master.
