I'd say 265/70/R16 is a good choice for a YD25 D22. Which brand of tyre is up to you. I'd go with the cheapest brand of AT tyre that your ego can cope with. We've had two YD25 D22's over 11 years. The current one is 8.5 years old & spends its week days towing a dual axle work trailer full of tools & cut down trees around the suburbs. We like outback touring & both of our D22's have done a fair bit of that. In 2015 we needed new tyres on the Ute & I realised that the camper we were towing had since 2012 had gone through some very rough roads with Chinese tyres on it & we hadn't had any dramas. So I took a punt and bought some cheap & cheerful Sailun AT's for the Ute. We were towing a camper trailer & went up from Adelaide To Mataranka in the NT & then out to Roper Bar, Nathan River Road, Lorella Springs, Borroloola, Hells Gate, Doomadgee, then home via Burketown/Cloncurry/Longreach/Tambo/Broken Hill. No dramas with the tyres. I drove it around for the next 9 months or so towing the work trailer in all weather & no problems, so when my wife's Pajero needed new tyres, we put the same tyres on it. We towed a caravan with the Pajero from Adelaide up to Camooweal via Gemtree & then back down to Alice & both the West & East MacDonnell ranges, Arltunga/N'dala & then Andamooka on the way home - still no dramas with the tyres! We didn't do much travel the next year, just a Flinder's Ranges trip & an separate Arkaroola trip, both with the Ute towing the caravan, with the Chinese tyres on it. The following year, we did a big trip in the Pajero, towing a camper trailer up through from Wilcannia to White Cliffs/Wanaaring/Hamilton Gate/Thargo/Quilpie/Windorah/Hamilton Corner/Betoota/Birdsville/Boulia/Plenty Hwy/Alice/home, still with those pesky Chinese tyres on it lol. In 2019 we did yet another Flinder's trip, then did another trip up the Oodnadatta Track/Eringa/Mt Dare/Old Andado/Santa Teresa/Alice/Kingoonya on the way home, in the D22. Last year we took the Pajero out onto the Nullarbor Regional Reserve, towing our camper, with the Chinese tyres on it. This was a massive step up in rough roads, as they were literally just heavily lime stoned wheel ruts. It was as remote as I've ever been. On the way back, we went up through the Gawler Ranges NP & onto Mt Ive, then up to Kingoonya via Lake Gairdner & then out to Tarcoola. On the same trip, we went out to Lake Torrens from Andamooka & then up the Stuart Creek track from there to the Borefield road/Oodnadatta track again & then home via Parachilna Gorge & Rawnsley Park. Those roads around Andamooka are the roughest I've been on yet. Early this year, we were due for a trip up the Silver City Hwy from Broken Hill, as we hadn't been up there since it was sealed, but the rain put paid to that trip (we were planning on going home via Walkers Crossing), so we thought about out around the talc mine between the Strzlecki Track & Arkaroola (Moolawatana Station) The rain got us again & we already had time off booked, so we went to Uluru. Before we went, I had new tyres put on the Ute. They didn't have Sailun, so I took their advice & bought Revolo LT tyres. They're OK. The trip was the 1st time in a very long time that we'd stayed on sealed roads on a long trip & I quite enjoyed it TBH. Just recently, we went up through the Gammon Ranges with the Ute towing our camper; Adelaide/Copley/Nepabunna/Balcanoona/Lake Frome/Weetootla/Arkaroola/Moolawatana/Montecollina Bore/Lyndhurst/Leigh Creek/Nepabunna/Mt Chambers Gorge/Blinman/Parachilna Gorge/Home. Like I said, buy the cheapest tyres that your ego can cope with.
