As I posted, quite often have problem with front wheel because forks are sometime not aligned properly when lifted and it's hard to put axle in.

Are you talking about bicycles or motorcycles here? I guess if you ride a 50cc scooter or maybe a 125cc bike, then the above could be the case ... but I can GUARANTEE you will not be breaking the bead on any 400cc bike and above by hand ... and even with tools it's a challenge.
This especially true with some street biased dual sport rear tires. Very stiff and most have a safety bead like tubeless tires have.
My DR650 and other 650's have safety bead wheels. This means you will see a knurled edge along the bead which tends to hold tight onto bead, making breaking it down hard to do.
Front tires are much easier in my experience and normal tire spoons usually work fine. DO NOT puncture your new tube!
(easy to do if in a hurry!

)
There is a LOT of technique involved to break a bead, experience counts. I've used 2 or 3 different bead breaking kits. ONLY the Motion Pro one seems to work fairly well ... if you know how! (it ain't that easy!)
On pure dirt bikes running NON DOT knobby type tires, these tire beads tend to break down much easier than street based tires.
My 17" tires are equally difficult as ANY tubeless tire. NO DIFFERENCE. Whether using a 50/50 dual sport tire like a Heidenau, Kenda, Shinko, Mitas or Mefo or a Avon Distanzia, Michelin Anakee or Shinko E705. Tough!
SAFETY BEADS ARE THE REASON ... but the safety beads also allow you to ride
that tire when FLAT ... and it won't come off the rim if you go slow. I've gone over 50 miles riding flat rear.
Getting the forks lined up to accept the axle is not too hard. The forks can MOVE to allow everything to line up. Use a bungee strap to hold handle bar to one side. pick up wheel and put it in position, first inserting brake rotor into caliper. Adjust fork tube and start axle, now slip spacer into place whilst holding
wheel in place. Continue pushing in axle, wiggling a bit. Now install other spacer on opposite side. Gently tap axle to push it through, make sure forks are moved to allow axle to pass through wheel.
With practice this is not too hard. What is hard is breaking the bead on a
rear tire.
