Myth 1: Maxxis tires are difficult to mount.
Three weeks ago I wrote a post claiming the myth was WRONG based on my experience mounting a 100/100 18 tire for 1983 RM 125. The mounting only took 10 minutes to complete!
Myth 2: A member posted in my original thread that mounting 19" 250F tires are a real bitch.
Today I learned Myth 2 is correct!
I spent a total of 8 hours trying to mount a 100/90 19 tire for my RMZ 250. I never had so much trouble mounting a tire. I ended up puncturing the tube TWICE! After I punctured the tube for the second time I went to the shop and purchased a Motion Pro bead buddy to give me a third arm while rolling that last 8 inches of bead. I also had to soap of the bead really good. Another odd finding is I had to inflate the tire to 55 psi to mount the bead correctly over the rim.
Why is a 18" tire far more easier to mount than a 19" tire? Both tires are the same compound and model.
Some people claim that WD40 is bad for the rubber.
I use Armor All myself.
The Shop
google them and nothing showed up for tires

Learn the Tao of Tire mounting. The Transworld clip and Vital clip are the best instructions shown.
I've thrown my tire irons into the garage wall in frustration so often, I have a drywall guy on retainer...
I agree with those who say to lube the crap out of it with wd40, be careful not to go past 90 degress to the rim with the tire iron and take small bites as you go round the wheel spooning the tire on.
That's when I decided to learn how to do it properly.
You want scary, try mounting a tubeless Trial tire. I only did it once, and can't remember how much pressure I had to put in for the bead to center. But when it did it sounded like somebody shot a gun in the garage.

and I do both (michelin trials and goodyear flattracks often)
LOL
My problem is only on rear tire. Prying the 'open' bead apart far enough to re-install the rim lock and then the tube, is the bugger for me.
Rear tires have gotten stiffer sidewalls in the past 3-4 years. I can swap a front tire just about using only bare hands, in comparison.
I just bought a Motion Pro 'gardening fork', for $26, that slips over the 'open' bead and allows you to hold the tire wide open, while finding the holes and keeps the skin on top of my fingers from being peeled off.
Thanksgiving Day I installed a new Dunlop 745 120 X 19 and with the new tool, my life is much easier and my mood is much better.
Maybe I should change to a jet ski NOT!
