Hi Andy
Dunlop seems to be doing well with their tyres lately. The Hilux and Fortuner we tested recently both came with Dunlop Grandtrek At’s (AT 25’s if memory serves me correct).
On road performance was exceptional with good grip and minimal road noise. One place where they did struggle is sand. But the AT5’s has a slightly more aggressive tread pattern, which does lead to a bit more road noise, but gains alot more grip in loose or wet stuff.
So from our side we would recommend the AT5’s, but let’s see what our community says. I’ll post it on our social media as well.
Regards
Jacques
