Thread: Hankook Dynapro ATM

Hey all..some very positive comments here but.....

Having now owned a set of these tyres (255/55/19) for the past 12 months and 40,000k I've had to replace 2 tyres due to side wall tears. I agree with all the comments about gravel road travel and I've been impressed with the wear and road handling of the tyre but, in both tear instances I've taken the vehicle into medium duty off road circumstances...basically fire trails, and experienced a tear on the front left 4 months ago and over Christmas a tear on the rear left. Was towing a camper in the last instance.

The trail was not particular challenging, low range and steep with shale rock sections....pretty sure the shale rocks did the damage but certainly would expect the tyre to handle the type of environment at the right pressure.

I had a conversation with the tyre supplier re the appropriate pressure. I typically drop from my road 42psi to 28 or 30 psi (30 psi with the trailer on). His suggestion is to run at 36+!...which in my mind is road pressures.

After the Xmas event, I increased the pressure to around 34 psi. and got to my camp site and back all OK.

I think the "bulgy" sidewall of this tyre puts it at higher risk in a harder offroad environment...purely my opinion but I've previously fitter Coopers LTZ's and had the GG AT2's on a 18" rim in a previous D3 along the same track (one of my favorite bush camp sites in the Brindies)

In saying that, took these tyres into outback NSW and QLD 4 months ago over 1000's of Km's of gravel roads with no issues.

I realize the 19" rims are the Achilles heal of this great vehicle platform but don't understand the technical reason there can't be a stronger sidewall developed. The things that irks me most is A: 300 bucks each time for a new tyre and B: odd worn tyres, 2 @40,00K's, 1 @ 10,000K's and now one brand new!

When I evaluate my next set of tyres, I'll be paying particular attention to the sidewall profile running at lower pressures....the person it upsets most is my wife who loves the remote camp sites but gets very concerned with equipment failures....so far the only failures I've had have in the Disco has been the tyres!

Put a set of 19" Hankook Dynapro ATMs on my D4 yesterday after agonising over whether to shell out $80 per corner extra for Goodyear Duratracs. Paid $258 at Tempe Tyres.

I realise comparing worn tyres to new is perhaps not entirely indicative, but noise level is same as the previous OE Goodyear HPs (70dB interior at steady 80kph in neutral on smooth surface), so I'm very happy on that front. I was a little bit circumspect going back to AT tyres after my experience with General Grabber AT2s on my previous D3, but these are just as quiet as OEs and Yokohama Geolandar ATS I've had. I might have gone back to Geolandars but for the lack of 19" for those.

I'm also happy with the looks, which I would call "not overly aggressive but purposeful". I think it looks better on the car than in photos, and better than Geolandars which I thought looked a bit tame for an AT.

Steering also feels more responsive now, sidewalls seem slightly stiffer. Ride is just a fraction knobblier (38psi all corners), but I can't be sure whether this would be true in a new vs new comparison.

I only do "proper" off-roading very occasionally, so hopefully limited mileage on such tracks mean I would be bloody unlucky to suffer side-wall issues some have kindly reported. Will report back after some more mileage.

You eastern staters do well on your pricing,best price I could find was $315 each[BJ Perth]I did notice they are carrying a lot more balance weights than the old Pirelli's,a bit more noisier but that could be the wheel bearings on their way out!

Hi Scott, did your father finally make a decision, if so which way did he go? Given your setup with 18" rims and D697s, I assume you do a fair bit of rugged offroad driving. Is this your dad's intention as well? I am still tending towards Duratracs, and 18" rims still not totally ruled out although like many others the cost is somewhat of an issue.

PS. Have enjoyed your D4 Build Tread

Wayne, it has been a long and drawn out decision that looks like landing on Duratracs next week.
Took awhile due to plenty of good reports about both Hankooks and Duratracs and then lots of ringing around for prices.
Yes he would much prefer the LT tyres but the 18" rims have been delayed for him due to budget pressures. I was able to afford them at the time so decided to go for it early.
He has a big trip this year towing the 2t van, so the performance of the 19" tyres during that will probably decide whether to proceed with 18's or not.

In April 2015 I purchased my current tyres, Hankook Dynapro ATM's in 255/55/19 for my 3.0L D4.

At that time I had 125,993km on the clock.

Since that time i have run these tyres at the placarded pressure and done a little bush work. Most of my time is spent on the highway at around the 110km/h mark. I check the pressures once a week and maintain the pressure from my own workshop compressor. I rotate the tyres at regular intervals although there might have been times when I have missed the schedule.

As of today the D4 has 180,304km on the clock. Roughly 54,000km on these tyres to date.

I decided to again rotate and measure my tyres. On removal of each tyre and testing the depth of tread over three or four spots on each tyre I found a remaining tread depth of:

RR @ 6mm
RF @ 6mm
LR @ 6mm
LF @ 6mm

No doubt there are slight variations to that measurement but my equipment can only really measure to the nearest mm.

These tyres when new had a tread depth of approximately 10mm. The loss of 4mm for over the 54,000km or 13,500km for each mm of wear is in my view really good! That said it has been my experience that tyre wear seems to accelerate towards the end of a tyres life. Nothing scientific......it's just my view!

Anyhow given the performance and durability to date I reckon it will be very interesting to see what I can get out of these tyres....80,000km maybe?

In the not to distant future I will be taking off on an interstate journey from WA to Vic and back towing my camper trailer.....lets see if that constant towing at highway speed alters things.

I hope that helps folks thinking about tyre choice.

How has your father gone with Duratracs so far.
I have been happy with them but I have swapped back to std tyres whilst in city as I felt the Duratracs were getting chewed up.
I wanted to keep them for trips outback.
Ive done 10,000ks on them.
Ready LGM's story on Hancocks I doubt I would get anywhere near 50K with these.

I ran Toyo MT 265/75 16s on my D2 and loved how they wore their noise level and performance on the road and performance off road, wish I could get them in 19 or 18 size under 32.5 for my D4. The wear thing probably is the extra weight and power of the D4 over the D2....
