I'd be surprised if they'd changed the tread pattern, unless one is OE approved. Dunlop will be able to answer you with specifics.
Owners of the Dunlop Grandtrek ST30 are broadly satisfied overall, but its most discussed qualities divide opinion. Tread life attracts seven favorable and six critical accounts, including sharply different replacement mileages, while noise is almost evenly split. Dry grip and high-speed stability receive more consistent praise, with four owners positive about each. Wet grip is evenly divided, and three of the 20 owners criticise aquaplaning resistance and three wet handling. Snow traction also draws more criticism than praise, so the generally favorable everyday road reports do not amount to consistent confidence in wet or wintry conditions.

I have driven pretty fast om turns, and the tires griped the dry pavement very well. This is my second set of Grandtrek st 30 tires, and I never heard the tires screech on either set. On wet pavement the car moves slightly to the left or right when I drive over big puddles of water. The tires have great traction in the rain. The first set of tires lasted 74k miles. The 2nd and current set of Grandtrek st 30 tires has 38k miles.
These tires have been on my 2012 Honda CRV from new. I have nothing else to compare them with. I am a very stable average driver and have just decided to change my tires although they still have 3mm of tread left after 9 years. No problem with them at all and have always been comfortable, stable and quiet. Coming up to MOT time so changing for something similar with lower price. Considering your vehicle always gets you lower motoring costs.

Came as standard on new RAV4, can't handle the moderate power on this car (225PS), wet performance poor (C rating) really gives no confidence, lateral grip is moderate but traction poor, it doesn't feel with any confidence that its clearing water under the tread effectively at all in heavy rain, the steering often feels aquaplaning light. Dry grip is not too alarming but they squeal like a pig at even very normal cornering without any power applied leaving you muttering under your breath 'what the heck are you moaning about?' at them. It entirely spoils any enjoyment of the vehicle at all as its too embarrassing to drive at even a normal pace. Whoever at Toyota chose these should fall on his ceremonial sword in shame. Fortunately after only 20K miles they are shot and I cam get rid of them! yay!
I inherited these tires with a RAV4. On the positive side, the wear has been brilliant. They hardly seem to wear down at all, not even half worn on the rear tires and over 18 months years old, 14,000 miles a year. The handling was not what I would have expected - I thought that they would be ideal as I live in rural Wiltshire and travel a lot on wet, muddy, icy and occasionally snowy roads. Sadly, the handling is poor and I have no more confidence in these tires than ordinary summer tires.Another example - the road we live on is down a slight hill, about 35% and in Feb / March 2018 we had some snow and it was impossible to get up the hill - just the same as my neighbours with their summer tires.. The M + S (mud and snow) rating of these tires doesn't seem to make any difference whatsoever. The crunch came when the driver in front of me, going through some roadworks, had to suddenly stop because of a manoeuvring truck. I really had to slam on the brakes. We were only going slowly through the roadworks (25mph) on a damp drizzly morning, but the car just wasn't able to stop in time. I changed them straight away to Bridgestone a005s (depsite the tire fitters telling me that I had loads of wear left) because I just have no confidence in them anymore. Don't know if the a005s as I have only had them for 3 days now.
This came with my 3rd gen Honda CR-V. Got them since the first time I bought the car and they're pretty okay. As an asymmetrical tire I think they're pretty decent if you're talking about performance, I got a good mileage on it. I drove about 60% city and 40% highway I could get 22.5 mpg consistently. Good handling and stability on high-speeds, great dry grip, good wet grip, very little waterplanning so it's good so far. The problem I had was with tread wear and noise level, and overall comfort on the road. I'm not sure why I just never felt the tires all that comfortable, they can be a bit rough on bumpy roads and noisy on high speeds. I can tell this especially after I swapped them with another brand just last week.
I had 4 of them replaced on 2015 and after good 28,000 miles and 3 years, 2 of those 4 tires went cracking and slips here and there when I climbed uphill. Got worried there so I replaced them with another brand tires and I wished I've done that earlier. Overall the tires isn't bad but there are other options out there for the price offering. Personally I wouldn't try get any of these again.
It came on standard equipment for RAV 4 Hybrid 2017. I drove its for 800km with a bitter dissapointment.There are OK tires, just ok because as most of the all season you cannot use it on winter. Small snow with a little bit of ice is the final countdown for its..I will no recomand this tires to anyone.
An average tire on dry, straight line driving on smooth surface roads but noisy on rougher road surfaces, do wear faster than I'm used to. Poor fuel economy/rolling resistance. Brake well during straight line heavy braking. On my RAV4 2016 back tires let go too easily and the tail hangs out as though riding on an oily road; worst tire I've ever driven on in any car for this. Given their overall performance on my RAV4 these are about the worst tire I've ever had and would not buy them again if there was another reasonable brand available. I will drive these tires to get wear out of them before off-loading them as the wet winter weather approaches and they become too uncertain and skittish. Could not recommend them based upon my experience and I don't push my tires up to their limits as a rule.
Best overall performance for the price. Superbly comfortable and quiet while providing performance. No aquaplanning while hitting puddle at 90-100kmh. Awesome. Will definitely buy again since it is a bargain. Was on BS Dueller 470 and it is a major step up moving to the ST30 with the same price range. However, these tires will wear out faster for surebut at that price range, i don't care. It is cheap, comfy, quiet, and fun to drive.
Dunlop Grandtrek ST30 tires were a reasonable choice by Toyota to install onto their 2013 RAV4 all-wheel-drive SUV. They are OK, with good straight-line stability and a comfortable ride. They have reasonable cornering and braking abilities but are rather noisy on most dry tarmac and concrete surfaces. The 4-cylinder engine with automatic transmission and AWD never challenges their grip during acceleration. These Dunlop tires are also quite good on unpaved dirt roads uphill and downhill, and through wet and dry mud, however one steep gravely section required locking the differentials just to get over a hump on which one wheel just kept losing traction and spinning too easily.
Remarkably good fuel economy for such a large vehicle is easily achieved: 8.0 liters/100km = 35mpgUK, while keeping within speed limits but not dawdling. The only demerits are the aforementioned noise on almost all paved surfaces, and quite poor wet road performance (wandering off a straight line, sliding wide on sharpish turns, and being pulled sideways by unavoidable puddles of water). Overall, I will keep using these Grandtrek tires until they wear out, then replace them with a different brand reported to be quieter and with better wet road grip.
