Until about 8 years ago I'd always used soapy water. Then I got some real tire lube and was amazed how much easier the job went. A gallon tub is about $15 and will last a life time - shoulda gotten it 40 years ago! Now I can seat tires (including tubeless) with about 35lbs pressure, using the manual tire pump.
