What variant of a generic AT tire are you looking for? Some are biased for metaled roads with others biased for different off-road conditions. You don't specify which backroad you're willing to drive. Cost of the tires doesn't maketh the driver.
3 years back I dumped my Dueler 684's because I didn't like them for their highway or marginal off-road performance. My alternate choice was more based on cost than rhetoric.
I was offered Dunlop AT25's for 15,000 THB with a subtraction of 8,000 THB for the Duelers. A total cost to me of 7,000 THB.
Not being a tire expert I got the AT25's, just to trial them. They were far superior to the Duelers: lower noise, a more compliant ride and to cap it all, they took me to the Tiramisu Waterfalls during a few days of rain.
Last Saturday, bought a new set after 55,000 kilometers - 18,000 THB less 3,000 THB for the old tires.
