Triton 2015 ran these for about 25thou.
Great grip, ok on the road never slipped for me and i country drive a lot and hit the mountains very regularly.
Last trip was around stirling up some very tocky step tracks.
Next day found splits around 3 tyres in side walls. All splits the same with not cut outs or chips in rubbers from the rocks.
Dealer arranged Bridgestone inspection but tbey said bad luck must have been a rock.
Not likely.
This leaves me one 60% tyre and the spare is new.
Tough choice from here
1st june 2018 update
Had 2 good ones so purchased 3 to make a full set again.
Just tortured them ober 3 days in serious high country tracks. Mud snow gravel rocks and rivers. Crushed it.

Well known fact these tyres were stopped from sale in or around 2016 due to the lugs coming off on scaly roads. Not sure how Bridgestone market this as a 4wd tyre? BF Goodrich is a far superior tyre. I don't think bridgestone bothered to rectify the problem, just kept it hush hush. It's all about the sales.

they are a strong Tyre but they are approx 70% for bush and only 30% on road, i have been on a lot of tracks that would have punctured other tyres for sure but these hold well but on the road slow down as they can easily take you off the road in wet conditions as they are like driving on ice. Its not bad if you drive slow but once you get past 80 klms it is very scary at times as they dont have much traction on the road

I have been running the mt for around 10'000kms and they are by far the worst tyre I have ever driven on in the wet.loosing traction on all 4 tyres doing 100km in the wet on a open road is not much fun.have had way to many close calls.they preform well in the bush but as soon as you hit the road in the wet its like driving on ice.i will be removing these tyres this week and they were not cheap

I have these tyers for a short ti me and have had a better response with them than the tyers i had that came with the vehicle .i whas not happy with them .i looked around and went to all the tyre fitters and settled for them..a good tyre.mate good to have them,

Terrible tyre uneven wear on them even with Bridgestone doing the wheel alignment. They screech around round abouts at slower than normal speads and tight corners. uterly useless to live with. Only positive is for a Mt tyre there good on sand. I had 245 75 r16. Noise is not to bad so a Mt.

Dueler M/T D674 tyres are a poor quality below average product. First impact fracture detected within 7 months (12,100kms), remaining 3 tyres failed in the following 6 months, all with impact fractures before 23,200kms. These tyres are sold as an off-road tyre to meet the "hardcore demands" of off-road driving (off-road means sticks, rocks, pot holes, creek beds, gravel roads, bush tracks, no roads). They incorporate revolutionary 3D technology to offer "superior durability" (above average quality capable of lasting/ resisting wear). Don't think they even got "off-road". Never had impact fractures before these tyres, go exactly the same places, and not had one since. Suspect Bridgestone got a faulty batch of these tyres.

265/75/16 22000kms they might make 30000 very dangerous on wet bitumen will not buy again 50/50 road paddock use only run 20
psi as at the recommended 32psi it does nothing but spin and step out side ways got caught after it was serviced and they pumped up tires thank God for stability control

Im really Happy with the Dueler Mt it is the first Muddy that I have had which is quiet on the Blacktop! I am also getting better fuel economy and the tyres are wearing really good so far 40,000km and still got heaps of tread! It is also a brilliant tyre in the Mud and on the rocks and not to bad in the snow, highly recommend them and so far can not fault them!

I have done approx 1000km on these tyres and first impressions are good. Initially a bit loud but the guy at the Bridgestone Select dealer told me they will get quiet after a few thousand. Bought them for my Mazda Bravo in 265/75r16 size. Will return once they have worn more so I can give a more accurate review.
