Dunlop  Grandtrek Touring A/S

These tires came originally with our GLK350 4matic. They don't have a lot of miles on them yet so I can't really say anything about thread wear. What I can tell is the different traction performance, since I had the chance to drive our GLK through last winter's 19" snowfall. First, the dry traction: it's pretty good, nothing negative that I could notice. The wet traction is also acceptable. There were no abnormal noises which I could notice so far and the ride is pretty comfortable (partially due to excellent Mercedes suspension setup, which is just about perfect for pothole-ridden streets of NJ/NYC areas). Now for winter traction: it is somewhat acceptable for slight amounts of snow and slow driving but absolutely not acceptable for driving through a deep amounts of snow. Doesn't matter if you still have enough clearance between bottom of your vehicle and snow surface - if the tires will lose traction (which these do in deep snow), you're screwed, especially when going up the slight incline. Overall they are acceptable for warm weather driving but I would definitely not use the vehicle with them if you just got a 10+ inches of snow "dump", doesn't matter if you have a 2WD, RWD or 4WD vehicle with locking differentials and a "low range" gear selection.

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...

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 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.

Replacing run flat Michelin Lattitudes which were a nice tire but the Dunlops were significantly less money ($325 vs $140 per tire) and the run flats can be a little harsh. The Dunlops are quiet, smooth and provide adequate traction in light snow/wet and dry conditions. Turn in is not as crisp as the Michelin but for an SUV it works just fine. I just couldn't see spending an extra $700 for a marginal difference in performance. In the 255/50/19 catagory, the Dunlop Grandtrek is a real value

Very Comparable quality of a Michelin tire for less money. Nice Soft Sidewall to give a outstanding ride plus quiet Ride for a work truck environment . I would put these tires on anything I own. To bad they do not produce in a lot of sizes.

These tires came with my Journey brand new from the dealership when we bought it one year ago. 2 summers and 1 winter and these tires are DONE. Luckily we had a very mild Minnesota winter last year because these tires really ----. I realize they are all-season tires and not dedicated winter tires, but to even fathom them being all-season tires is proposterous. They MIGHT slide by as 3 season tires, but even then they don't really do all THAT well in wet weather either. Light rain seems fine, but a deluge/downpour with lots of standing water on roads and these tires buckle; they just can't handle anything that is less than perfect. Maybe alright for Arizona or Texas, but not the severe weather we get here in Minnesota, that is for sure. Unfortunately there aren't many options for this odd 19" stock wheel Dodge slapped on the Journey, and none of them really seem to get very decent reviews, and the ones that do are ridiculously expensive. Either way, don't waste your money on these wheels, especially if you get anything resembling a real winter. They won't last much past one year, maybe two if you don't drive much, and won't get you anywhere in light or deep snow. I pity the fool that tries to take their vehicle out in a snowstorm with these tires, even in an AWD vehicle like the Journey. And the Journey surprisingly has a very good AWD system. Just need the tires to compliment it.

Worst tire performance experienced in many years. Can't say how strongly it's recommended to buy something other than the Grandtrek Touring A/S. Very disappointed and surprised Lexus chose this as one of their OEM tires.

The Dunlop's came stock on our new RX450h. Poor traction from a standstill in the dry with any temperature below 50 degrees, just flat out unacceptably poor in the wet regardless of temperature and a bad joke in any kind of snow. ABS and traction control frequently had to intervene with even moderate throttle or brake applications. Ride quality was well cushioned but the sidewalls felt like they flexed to much, resulting in a somewhat bouncy and unsettled ride. Increased tire pressure up to 7 psi over factory recommended and ride improved only a little at the cost of increased noise. Impact noise was okay, with the tire tread droning just a bit above 30 MPH.

Figured the tires just had to be broken in...waited 1000 miles with no change. Threw the Dunlop's tires out despite the low mileage. On a recommendation from the Lexus forums, replaced with Yokohama Parada Spec X tires which transformed the vehicle performance... so much better to drive now. Only negative is fuel economy is down .5 to 1 MPG, but drastic safety and performance improvements are well worth it.

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

Don't buy Dunlop tires for your own good. Those tires lasted only 18000 miles, and I called the factory said the tires have no tread wear warranty. The worest tires I ever bought.

I didn't expect these tires to wear out after only 20,000 miles and I rotated every 5,000 miles. These tires came with the vehicle. I won't be replacing with this brand. Very disappointing. The road noise was pretty high too. If I didn't drop my speed to 20 mph, or under, going around this turn in a local road, the tires would squeal and people would stare as if I was doing 50 mph around the turn.

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.
