My previous LC Prado (same model) was equipped with Bridgestone Dueler Sport, which allows me to make the comparison with the Dunlop Grandtrek AT20.

On dry roads, with Dunlop Grandtrek, braking distances are increased and handling worse (slide of 4 tires when cornering).

But on wet roads, it's a disaster. When cornering - even at a slow pace - the car slides and you have to drastically slow down to keep it on track. And when braking, it's even worse. The car skids, slides and only slows down a bit - but it’s like the car doesn’t want to stop or to keep on track. This tire is really bad, dangerous especially in the wet.

And, having raced on ATV for many years, I‘m supposed to know how to keep my car on the road!

Fantastic tires in all conditions and unbeliveable wear rate!

I have never strayed from these tires since 1998 as standard on a new Land Cruiser Colorado, followed in 2005 on a new LC5. However I agree with many comments about the balding on the shoulders & this appears from 35k in my experience. I can admit to under-inflation on some occaisions but I also run several other 4x4 vehicles with other tire makes & it seems to be unique to Dunlop AT20`s. Eg currently I have 5-6mm of tread but on only 60% of the tire surface! Two sets averaging circa 60k miles on all fours sets, however I have rotated (as per the manufactorers handbook) them over this period & the more regularly you carry out this excercise the longer they last. They are very stable & I can on occaisions drive very quickly without any drama whatsoever in wet & dry. Never been remotely stuck in snow but they are not proficient in the mud!

Original fit on my 2008 Toyota Landcruiser 3.0 D4D VXL Auto 5 door. These tires were absolutely dead after 30,000 Kms. Main Toyota dealer told me to run the tires at 2.2 bar, not 2.0 bar, as the original tire pressures are to make the vehicle ride like a Lexus. Have now been running on Kuhmo Road Venture KL51's for the last 60,000 Kms at 2.2 bar, and they have been excellent in all respects, and make a show of the OE (and ridiculously overpriced)Dunlops!

I replaced the front 2 before driving from Dublin,Ireland to Arzachena, Sardinia, Italy, Through England, France, Corsica then into northern sardinia, all motorways and secondary roads June 2010. could not fault the tire, so far. I have done some off-roading too, soil and stone, and all ok there too. still too early to give a full judgement on the tire. best advice is to research tire well, and decide what you want , summer, winter or all season.

I don't have much to compare this to, other than 2x previous Jeep Grand Cherokee's and a Discovery + Pajero (15 years ago).

These tires are OK - The front's are down to 4mm and the rears 5mm. However, I am very disappointed to be feeling nervous about the front tires, despite them still being fully legal. They are bald on the shoulders - and they LOOK bald to passers-by. I am waiting for a do-gooder to report me. Some might say that after 34,000 miles this is acceptable. I don't feel this way - maybe I was spoilt by the Goodyear Wrangler SP's on my JGC's which did 50,000 miles without complaint, despite the fact that I gave them a beating. The Landcruiser doesn't lend itself to aggressive, wild cornering (strangely the JGC seemed to be 'gasping for it'). So I feel strangely let down by these tires.

Also, they are now 5 years old and during the last visit to the tire garage (wheel alignment) they were all tutting and grimacing over the cracks appearing in the sidewalls. Mind you, this car did spend the first 2 years of it's life being cooked in Spain.

It all adds up to a feeling of disappointment.

Although I will probably buy again, it is only because of inertia and fear of insurance companies terrible behavior in trying anything on to wriggle out of paying-up in a nasty situation.

By the way, these AT20's were OEM and supplied with the car.

I would love some proper winter tires on this car, but I cannot justify it when I am already leaving everything behind in snow (4WD + proper diff. lock + grunt + OK all-weather M+S (no mountain/snowflake)) and have got to an age where I now drive sedately.

I have been skiing many times in the Landcruiser on the AT20's and in the JGC'c on the Goodyear Wrangler SP's - I cannot remember ever having a problem with either of them. I haven't/didn't have chains for either. Although I do remember driving a Mercedes 300D up from Zurich through the Fluela Pass, past Klosters and Davos on our way to the Engadin Valley and N Italy - all I had on were summer tires and chains on the rear. I honestly thought I was going to die of fear - what a bf I was. I had the Swiss and Germans buzzing by me without a care, on their winter tires and I was drenched in sweat from fear as the car slid everywhere but where I wanted it to go.

That's all.
