we got ours (rugby club has about 10) from a mechanics/tire seller. there all completly non road worthy and thread bare. but still nice and heavy. also try scrap yards, lorry repair yards and quarrys.
700lbs sounds like a good flip. we have none near that size.

For your tire flippers, where do you get a hold of these giant tires?
Also, how difficult is each weight? Is a 700lb tire pretty good?[/quote]
Look for someone that sells lots of tractor tires. I found mine in a farm field and asked the farmer if I could have them. He told me he wouldn’t pay me to take them. I said I just want them. He was more than happy to get rid of them.
700 is good most Amateur LW strongman events seem to be around 600-700lbs. But depending on tread and shape some heavier tires can be easier than lighter tires.
