Changing tubeless tyres can be hard, but with inner tubes, it can be a right pain. Please find below a very helpful article taken from CLASSIC MOTORCYCLE MECHANICS.
Back in the day if you got a puncture you fixed it yourself, often by the side of the road. With the advent of alloy wheels, tubeless tyres, roadside assistance and tyre specialist garages the most involvement many have with those black rubber hoops full of air is taking a wheel off the bike and getting someone else to sort it out.
It's quite common to order up a pair of tyres for an ongoing restoration, drop the freshly built wheels off at your local bike shop and simply collect them the next day. All of this is very convenient but what happens if you've bought some new rubber for a bargain price at a show and your local bike shop or tyre specialist wants a small ransom to fit the tyres? Or what about that damn puncture you inevitably find late on a Saturday night a few hours before you're due out on an early Sunday morning ride? Can you remember how to sort it out; does the workshop manual really explain what to do, have you got the necessary resources to do the job?
Please Note

Running in
A New tyre will need at least 50 miles running in before it gives it best and for the first mile or so can be lethal if thrown hard into a bend for example.
The best tyre in the world will not give it performance until it is up to temperature.
