Do they not sell them in the US?
If so, that's very strange. I would have thought with the larger off road market, Goodyear would have sold them.
They were made in South Africa, my tyre supplier booked his order in November and they were delivered mid January, i had mine fitted on the 29th.
They are an expensive tyre though, they were £184 each. plus £46 delivery and £75 fitting.
At the current exchange rate of £1 - $1.52 that works out at $279 a corner, or $1,398 for 5. Plus whatever shipping and fitting costs are.
I chose them over the General grabber AT, as the AT didn't cope as well in muddy conditions, Scotland has loads of muddy places to drive in, so to avoid getting stuck and having to be recovered, i chose the Dura. Plus it has that exclusive factor as well, being a rare tyre.
They are good in snow and ice as well, but obviously you drive to the conditions as 2.8 tons can and will slide for a good distance if you get it wrong..
