I just changed my rear tyre (I'm English) and I had to use 6 clamps to get the bead into the well of the tyre.  It seemed much harder than it did about 30 years ago - perhaps because the tyres are tube/tubeless.

This is the one thing that I think is completely worth the money that the dealership charges.  

yeah, I have a dish soap water solution that I spray and wipe on.  I will see if K-Mart (headed there for some other things) has the car door protector.  I've got the Motion Pro Rim Shield IIs, but they suck.  Both have split along the rim bend...I've tried oil container plastic and they're okay, they just cut really easy on the back rim.  Maybe I just need to try it again.

Ive done it at home.
I prefer the $30.00 method,
The Idea of "doin it all myself" is real romantic, but the reality of spending all that time & effort on something when I COULD spend the same time on something else, Heck, ANYthing else, mowing the yard, washing dishes, changing the oil in a car,, ( Gee,, I can do ALL of those things in the time it takes to do the rear tire!),, I wont ever do it myself again,, UNless,, No One will do it for me,

I have 4 tire irons, and on some tires you use them all.

Remember, the goal is to get the part of the bead that is inside the rim to go down all the way to the bottom of the center well, this gives enough room for the "struggle part" to slip on.   Don't ever let the "on" part of the bead seat out on the rim -- this makes it impossible for the rest of the bead to slip over.

  Sorry, I don't own a Savage/S40. Hope to some day. I did the tire replacements on a 2005 Kawasaki KLR650 I used to own. I used 3 tire irons and got it done. I used Windex for a lube, and talcum powder on the tubes as a way to keep the tubes from having a twist in them. I didn't have a motorcycle jack. I used a combination of the side stand, a small bottle jack, and I have a couple of car jack stands. I am now 59, and have one a few flat repairs/tire changes over the years. All were tube type tires, and I have never pinched a tube yet. Yes, there may have been a little blood and swearing, but it feels good to do it your self. Actually the hardest part with the most pain was trying to get the valve stem on the tube, through the hole in the rim for it. Nothing too serious, just some pinching of the fingers. Using the 3 tire irons worked well. I wouldn't do it without 3, and I wouldn't try to use another tool like a screwdriver, as damage to the tire and/or tube is likely. And don't forget to air up the tire and get that bead seated and test for leaks BEFORE you reinstall the wheel.
