Flipping a 452KG tyre (it's an Australian tire)

Pic from this Past Sunday. I wrestled 3 ugly singles with this beast. Emailed the mfger for the weight. They said brand new this tire is 452kg! That made me feel a little better about the struggle..my forearms still have a deep sore (need some handles on this thing:) #santamonica#LosAngeles #lasvegas #saintlouis #getbetter #getstronger #tireflipping #fitness #powerbuilder #theycalledthetiretyre #452kg #fitfun #thestruggle @theamazinglucas, maybe I could borrow your #liftingstraps

When I toured my new gym; I was intrigued to see two tires.  I have never had access to big tires.  As soon as I saw them I started sizing them up.  I haven't tried this before so I did what we all do... I watched a Youtube video.  But instead of just watching any yahoo that uploads a video, I made sure my source was reliable.  I watched a tire flipping tutorial by Pro Strongman Andy Deck. 
I warmed up with the small tire, then went after the monster.  I got 3 singles.  The first one I wasn't sure I'd get - so I didn't bother setting up a video.  But I got the 2nd and 3rd.  Obviously, the form has room for improvement - it was the opposite of explosive and I see a little flexion in my spine.  I was a bit frustrated at how difficult it was.  But I was glad I was able to get it off the ground.  As seen on the video I had a tough time figuring out the grip.  Not sure I ever got it.  I think I just kind of cupped the tread and squeezed - which destroyed my grip (or) maybe combining the tire flips with deadlifts killed my forearms.  Either way - ouch! 

This felt tough and I failed on the 4th & 5th attempt.  The tire is a Toyo tire.  I was extremely curious of the weight of the tire.  I wrote down the details stamped on the side and scoured the internet and I could find similar but not the exact type of tire.  So I emailed the manufacturer.  And they responded, "A new 26.5-25 28 ply G18 weighs 452kg."  For our kilo intolerant friends that's roughly 996 lbs.  That made me feel a little better about it's toughness.
