Getting old tire off no problem at all - Just muscle it off with a couple of old style lug wrenches with the pointy ends, or with small craw-bars, or if you are city folks with store bought tools that don’t double as agricultural implements, tire irons. – Use dollar store dish detergent as a lube.
Getting the new tire on much bigger problem. – Used to muscle them back on with lug wrenches or craw-bars plus the aid of the old-lady and the kids. – The bigger the tire the more mechanical advantage needed. – Have even out muscled tractor tires (with the aid of a very large friend and (2) idiot bars + full size craw-bars) – And, oh yeh, dish detergent
About 20 years ago got a little smarter. – Would pull the beads together using about 8 pieces of parachute chord and teamster hitches. With the beads together could just pop the tire on, Works with lawn equipment, doubt that it would with anything stiffer.
For something stiffer saw this on CycleFish someplace & bookmarked it. The ratcheting tie-downs would be great for making the bead too. All this said, for my powdercoated wheels will probably farm the job out.

99Savage got it right, works with most motorcycle tyres...and y'know what...He also knows the best tool to do the job and make it a whole load easier too!!!
Dollar Store Dish Detergent!!! Best tool in the box for a whole load of applications!!!
Go to any "Mechanic's Workshop" ... If he aint got dish detergent there go somewhere else!!!
I Buy Tyres - I Fit My Tyres - I Ride Happily - Total Cost = Just The Tyres!!!
(just a small hint though, get a whole bottle of dish detergent poured into a suitable container that a small paintbrush can fit in...allow it to evaporate and get thicker-usually takes a week or so - and when left and it dries out just add a small amount of water each time to turn it more gooey than runny ok? oh and, leave the brush in it, lol, always ready for use then, no need to go find another one)
You know those coffee cups you get from the Gas Station? Get the large each time - keep the cup - it will hold dish detergent for AGES without losing integrity - and when it does, stick the whole cup and contents inside another one...lol... I have one with dish detergent in, one with Copper slip in, I have one with Molibdenum base grease in, I use them for paints, for oils, for temporary containers..... and as soon as you are finished with it chuck it in the bin, its disposable - nothing to wash up!!!!!
