Dunlop Grandtrek Touring A/S 

Quiet, comfortable, and delivers a confident driving experience in wet or dry conditions. I live in Florida, so I don't drive in snow. But in the conditions in which I drive, whether cornering or driving in city or highway conditions, this is an excellent and very satisfactory tire. The key attribute is that I simply do not think much about the tires while I drive.

New car / OE tires, have driven 11,000miles at this point, rotated tires at 10,700 and all have 9/32" tread, should easily see 50,000miles before replacement.
I have not yet driven in snow/ice, but the lack of sipes on the tread don't give me much confidence plus they're pretty wide for winter tires. I will probably look for a winter set before the first snow.
Ride is good, originally I inflated to the factory sticker 48psi rear and 45psi front, they sounded like overinflated basketballs on bumps and I could feel expansion joints pretty well. Lowering just a little to 45/43 changed the sound and ride, I am happy.
Handling is crisp enough for a 5000lb SUV on (255-50/19) standard M&S tires, a little better than expected.
Rain handling is good, running 75mph in heavy rain doesn't seem to upset them, nor does taking a rain-soaked exit ramp a little fast. Dry feels good too, hitting an exit ramp at 2x the posted speed they feel balanced and responsive.
I picked up this car and drove to Tire Rack hoping they'd give me something for these tires and I could move into a set of Michelins (my normal go-to brand for most of my vehicles), I've never had great luck with Dunlop (re-balancing, harsh ride, etc.). Unfortunately there was nothing they would do to credit me for take-off tires, they're really not a used-tire dealer so I'm not surprised. Anyway I decided to run these at least until winter (have driven 11,000miles in 3.5 months, I'll wear them out) and am surprised with the ride and performance. Reading the reviews here from Lexus owners it sounds like these tires are poor to marginal at best, but it is possible that the MO (Mercedes spec) tire is different than the Lexus spec, ... or maybe it's the vehicle.
Also, I wanted to switch to LRR tires thinking I'd get better mileage, am averaging 33.1mpg so far on these (dash computer agrees with cumulative fuel purchases) so they must be fairly low rolling resistance (not sure what it takes to earn an LRR on the sidewall).

These tires came OE on my Mercedes GLK and I have been quite impressed with their performance in both wet and dry. The dry performance is the better with some harshness over rough roads. I expect to replace with 45,000 miles on a heavy vehicle. I will consider this same tire again or another Dunlap tire because they provide very good balance in all performance categories.

These are OEM and were on the vehicle when we got it used at 17K. This is my wife's vehicle and we also use it for trips. I was a bit shocked when reading the other reviews that mostly hated these tires. We replaced them at 52K because the fronts where feathering on the edges, not surprising since we have never had the vehicle aligned or the tires rotated. The rears were 4-5/32s and the fronts where 3-4/32s. Certainly could have driven these another 10-15K, or more if we had taken care of them. These were pretty quiet tires, something I usually notice. Even before replacement they were pretty quiet (my wife concurs) when I intentionally listened to them with the window down after reading the reviews. Never had a problem with rain, never lost traction, and never hydroplaned. Handling was fine for this vehicle, there was never any lack of confidence in them. Maybe we had a good experience since the vehicle is AWD unlike many other reviews, or maybe being a hybrid had an effect. I would have purchased again except the price was way too high so we ended up with the Bridgestone Duelers 422 Ecopia for over $100 less per tire and excellent on line ratings. It's very early but so far there's very little difference between the performance of the new Bridgestones and the 52K Dunlops, yeah I know that sounds crazy but we had very good luck with the Dunlops, go figure...

Reviews for this tyre seems gone wild. Mercedes drivers loved it but Lexus and Audi hated it. I think my experience might have solved the myth:)

This is my second sets of Grandtrek. My first one was 235/55R19 (240 wear, with LRR), a direct replacement of the OEM Michelin Latitude Tour on my Audi Q5 3.2. They were very comfortable, quiet, okay traction dry and wet, though showed some uneven wear at the end (after 40K miles). Snow performance was weak...

I bought another set a couple of months ago in a different size, 255/50R19 (200 wear, no LRR, Mercedes OEM). Reason? It was cheap ($150). Guess what... this set feels VERY DIFFERENT, almost completely different tyre. They offer solid traction (the extra width surely helped too). I usually turn corner very fast and often pushed the previous 235 tyres to screaming (I do car racing on track so bad habit:). But this set easily lift the limit for another 8-10 mph in the corner very stably. I go skiing a lot, crossing Sierra Nevada in snow often. They behaved MUCH MUCH better than the previous set. Very solid traction changing lane in heavy snow (speed was around 40 - 50mph). And very quick to regain the traction after quick turn on snow/icy road.

Biggest problem? OMG they are noisy... MUCH worse than the previous 235 set. It feels like wood barrels were rolling under!

Conclusion: the Mercedes OEM one (255/50R19) is great and cheap except being noisy. The non-MB one (235/55R19), hmm, almost opposite...

These were the OEM on my wife¿s RX 350 AWD. She is a very cautious driver as she always has a child in the car. These tires lasted 45,600 miles before two tires reached the wear indicators so I replaced them with Pirelli Scorpion Verde all season Plus which I paid $111 per tire on tire rack with a $70 rebate. These Dunlop were surprisingly quiet, smooth, and comfortable. So much, the vehicle felt as if it were not connected to the road. After 30,000 miles the noise increased but bumps were still absorbed very well. If the price of these tires were $125 instead of $200 I would consider them again. I have Michelin Premier A/S on my Volt and these Dunlop¿s were comparable in comfort and noise. Maybe we were lucky to get so many miles, we did rotate every 5k miles and had alignment done 3 Times. They never lost Air or had a flat or blowout or had any other problems with these Dunlop tires. Since this car is AWD, we have driven on gravel and dirt roads and they performed as an expensive tire should. I will review the Pirelli when we get some miles on them. However, just from the few miles I¿ve driven on them, the bumbs are much more pronounced and the tires fell a lot stiffer and more performance oriented than these Dunlop¿s. Overall I am satisfied with this tire because of its comfort and quiet performance, which match the Lexus very well.

This is my 3rd set of these tires. They ride great and for our high-speed highway driving, they have been great. We do an average of 110 miles a day. Also got us out a dump of snow a few years back. I like em. They work great for us.

Worst mainstream brand & OEM tire on a brand new vehicle in 40 years.

We just now approach 24000 miles on our 5 year old GLE. Mostly local highway and interstate. Relaxed driving in a rural state. Primarily used during the winter months, or trips with family. The tires do not inspire confidence in winter driving and I'm unsure why they're even considered M+S. Tread pattern is old school and lacks features & sipes for winter driving. Worse OEM tire than Continentals on our ML, though quieter those. Tread wear is even, vehicle tracks great etc so the wheels or tires are not damaged, no edge wear, etc but we're at 3 to 4/32, visibly close to the wear bars; so the tires have to go at only 24000 miles. I don't want to risk driving with them this winter. Incredibly bad longevity.

These Dunlops simply do not last and shame on MB's bean counters for fitting such tires OEM.

One thing is for sure. Dunlop joins the list of Continental and Hankook ... all now fitted OEM on MB ... unbelievable, really! I will never buy anything these brands sell, if I have a choice.

Back to Michelin.

these tires were installed new on my car. there is a noise from one of the tires and i cant figure which one. Also in snow these tires are terrible. Even with antilock brakes SUV kept going. Do not feel safe with these tires on my car. If you live in the south maybe these would be OK. Replacing these ASAP

These came new on a CPO '15 RX350. This is 'V2' made in Japan.
Can not think of any worse tire that I've driven on.
Absolute junk. Hard ride. Resonant/radiated noises. Tread squeal noises. Bad mileage, worse mileage when cold. Mild grip in the dry. Low grip in the wet. Next to none in the snow. No ice traction. And the cherry, rapid tire wear.
Hope someone was fired at Toyota for choosing such a terrible tire for their Lexus {Luxury EXport United States} product.
and it doesn't help that the OEM wheels {19" 15 spoke} are overweight-35 pounds

This is the 2nd set of Dunlop’s on our 2015 GLK250. The car requires run-flat or MOExtended due to the DEF tank and subsequent lack of spare tire. When we bought the 2nd set of tires these were the only run-flats available in this size. These tires barely last 35k miles, each time. We lived in PA and ran these tires in the snow and they did well, even on an emergency trip through Ohio during a snow storm. Other than the treadwear they performed as you would expect an original equipment tire on a Mercedes. Still, the positives don’t outweigh the negatives or in this case the accelerated tire wear. A tire of this size and price range should see at least 45-50k miles. We are trying continental run flats this time.

Absolute garbage. 20,000 miles on SUV. Tires are down to 5/32. With 200 treadwear rating, that's not surprising, but still unacceptable. There is no doubt that the reason Mercedes puts these on is because they are 1.cheap and 2.probably last just long enough for the 70% of people that lease these SUVs.

There are so many better options out there, no reason to buy these. I don't think they'll make it to next winter, which is fine since I'll be buying some Michelin Defender LTXs anyway.

Great tire if you don't mind buying new ones every 20K miles. With the 280 treadwear rating I knew they wouldn't wear very long but they came brand new with my CPO Lexus RX350. I normally don't buy any tire that has less than a 400 treadwear rating and now I know why. I would expect to get at least 30-40K miles with any tire for this car.
