This is the definitive guide, contrary to popular belief you don’t need to spend money on rimstrips and valves, just some sealant and you can even save money on that.
tyre/rim combintion is important so do some research on that first, I have had perfect results with stans and rolf dolomtes and various continentals. I have never need to use soapy water with these tyre rim combunations either.
If your tyre is a tight fit on your rim you may be able to just use a track pump, but a proper compressor makes it easy(at least 10 cfm and 2.5 hp with a 25 litre tank or greater, the one they often sell at aldi is great and comes with loads of other interesting air tools 8) )
