The Dunlops came factory fitter, made in Thailand. Still lots of thread on 45000km most done highway and beach driving. Road noise at 80-90km are really high.

A few years 265/65R17 60000 January 2, 2024
Have just replaced my third set of these tyres after 60,000 kilometres and there would be still enough tread to go another 10,000. Both previous sets were changed at 60,000. Only had one puncture - a teckscrew. Nearly all driving was done on bitumen. About 20% towing a 2.5 ton caravan. On the very rare occasion travel was on dirt road, beach or off road they seemed to perform well. Very little road noise. These tyres are excellent for my use. Wear has been very even. No complaints. Would definitely buy again and recommend to others.

Came stock on the vehicle. Useless off-road, no grip, clog up with mud. Definitely a highway tyre, but even then, they’re bad in the wet. The mud tyres I replaced these with are better on the road in the wet. Didn’t last long before I had to replace them.

6 months 265/65R17 11000 March 14, 2023
This is my second my 22 prado in 12 months as I turn them over every 15000 ,so this basically 2 reviews in one ,Useless offroad, even when only had 1000 kms on them. I'll give them credit on gravel for not puncturing on some forest tracks but as soon as there is a bit of wet or mud even on gravel sandy roads , these are terrible and give no confidence at all, got stuck in a simple creek crossing that was purely a trickle , and had to engage 4LO and lockers to move through , ridiculous, , these seem to behave more like a HT tyre and are best suited for caravans on highways or running to coles . terrible off road tyre , toyota is better to move to BF trailheads as an OEM tyre

A few years 265/65R17 80000 December 30, 2022
I had 2 sets of these. The first were 255/70r16 that came fitted to the car when new. They were made in Thailand and absolutely deadly in the wet. 2nd set. I changed the wheels and had 265/65r17 tyres fitted. These were made in Japan and a completely different driving experience to the factory fitted tyres. Good on road dry and wet grip. I did approximately 1,500kms of light snow driving with these and they performed well. Great dirt and gravel road performance. Honestly had better cornering control and braking than most off road tyres I had used in the past. No chipping or chunks breaking off the tread blocks like I have experienced with other tyres. Good ride comfort, they handled bumps and corrugations really well. Low noise levels on road. I replaced them at 83,000kms with 2.8mm of tread remaining. They where still legal but my experience with all tyres in punctures become a lot more common on gravel as the tread depth gets below approximately 3mm. Added bonus - a lot of people remove these when purchasing a new vehicle to fitt more aggressive tyres. These are usually available for a big discount. Team that with good tyre life and they are great value.

This my 4th Pajero & I find these Tyres a good all-rounder for my needs especially on long distance highway drives, they give a comfortable & quiet ride. I usually get around 50-60 thousand KS. from them & that's towing a 21' caravan from time to time. I'd recommend them. Eric, North East Victoria.

Came stock when bought the Prado new in 2020. After 45k they seem to be holding up ok. 99% of driving on the black top with the rest on the beach and gravel. Hopefully last until 60k when i will look to upgrade to something better. I guess these tyres are a basic AT tyre for Toyota Prado and i have had no issue thus far. Would i recommend the AT20? Unlikely, unless wanting a basic AT tyre for the blacktop and a small amount off road.

After a few weekend 4WDing trips with these and driving over 50kkms on a mix of rural, gravel, dirt and bitumen roads, on the stock tyres that came with the car, I would say they’ve done pretty well to keep me going. As they’re wearing down to a bit under half tread (4.5-6mm), they’re slipping a bit more around roundabouts in the wet on the Ute with no weight in the back, but that’s just carelessness. To sum it up, these are great tyres for a weekend warrior, they don’t look too aggressive, and they don’t look like a bottom end ranger tyre option either. All in all, a great tyre that has taken me everywhere.

Early days but quiet tyres, steer well, and good in the wet, especially in 4 high. Mainly city driving so far. About to test on and off road on extended regional trip.

Bought the pajero new with these fitted and didn't really like the look of them but...they have really surprised me. Sooo quiet and great grip on road wet or dry, I am looking to replace them now and after looking at other tyres i will probably fit the latest version of the AT20 which is the AT22. Great wear out of them, 82000 Ks. Very happy.

Factory fitted tyres and do the job for driving on the roads (as they're designed for) just fine. Bit sketchy in the wet on a roundabout if you enter too fast, and in heavy downpours while towing. They were totally fine when I took them on the beach a few times over Christmas, and even towed out another vehicle bogged down to the axles in very deep dry sand. I would prefer an AT tyre that has more off road ability though. If I was sticking to the black stuff then tyre is more than fine.
