Following reasonable reviews, I had a pair of these fitted about a third of the way into my journey from the UK to Thailand. This was on the basis of them having a long life and being suitable for the occasional unpaved roads I might encounter from Russia onwards.

My bike was a Honda Transalp 700, ridden solo, and with only lightly loaded panniers & top-box. I inflated the rear to around 35psi (being mid-point between the solo & pillion recommended pressures), and the front to the correct amount. My riding style on this tour was quite leisurely.

Grip was good on dry roads, but white lines and the like caused a lot of weaving around. Wet grip was acceptable, but I took it steady. In the mild off-road sections, they performed well.

I suffered two punctures in the rear, both caused by nails, and these were repaired immediately with no riding on flat tyres.

Problems arose after about 6000 miles, when small cracks started to appear at the base of the knobs on the rear tyre, but with an estimated 5-6 mm of tread left, I carried on. The front was fine and did not show any similar issues.

These cracks/tears slowly propagated over the next 3-4000 miles, and at 9500 miles, I woke up one morning to witness about 3 of the knobs had completely torn off the tyre carcass, exposing the tyre cords.

In hindsight, I should not have ridden with the tyre in this state, but simply in the middle of Thailand, I had little choice but to ride 300 miles slowly to a tyre dealer to have replacements fitted. On arrival, another 2-3 chunks had come off, suggesting it would not have lasted much longer.

So, if this had have happened in a more isolated place, it would have been a major problem, and on that basis, I feel this is unacceptable from a 3 month old German built tyre. Although the front was fine, I can not recommend the K-60 Scouts any more.

Interesting. I run K60's, and although I don't do much off road stuff they are holding up very well on my F 800 even when sometimes fully loaded. 12,000Kms so far and no problems.

Can't help noticing that all the issues you've had are on one side of the tyre, which could suggest acute stress on one side , perhaps caused by the tracking being slightly out and overheating up one side of the tyre more than the other, with the subsequent failure.

Yes very.....I have been running a K60 Scout rear and a normal K60 front for 5000 miles on my XT600E and 4700 of those mile were mixed terrain on my trip, and they are doing really well, better than the Sahara's I had on before.

Maybe just a faulty tyre?

Our sample size is too small to be meaningful, but I’m another user who’s run through a couple of sets of K60 Scouts (Triumph Bonneville) both solo and as an outfit on snow a bit of gravel and a lot of road. The sidecar will tend to reveal reaction to odd loadings and I’ve nothing but praise for them (and not only because Heidenaus never tried to kill me like Pneumats on MZ’s back in the day!).

Yes, I still have an involuntary shiver when I remember those on my old MZ but the worst of all time must be the Inoue's fitted to early Jap stuff. It was like riding on ice every time it rained.

This is very surprising Russ, thank you for sharing. I suggest to send these pictures to Heidenau directly and without delay. Careful selecting an alternative, maybe a MEFO or TKC-80 is you can find these locally, but unlikely to last as long.

Here's Heidenau's address:
Reifenwerk Heidenau GmbH & Co. KG
Hauptstrasse 44
01809 Heidenau

I only have a positive experience with those mounted on my 690R and I give them hell each time. I like those tires very much though scary at times on wet surface. Ride safe!

I had exactly the same issues with my Heidenau K60s. Huge cracks around the knobbies and parts and bits starting to come off. However I replaced that tyre before it became as bad at Russ' tyre. Had 12 k kms at that time.

Thanks for the comments, and I will send the thread link to Heidenau.... ( two weeks later, no reply)

I do agree that it is probably related to heat, although the failure mechanism might be complex. The ambient temperatures were around 30 deg C, but the Transalp does have a large exhaust catalytic converter mounted right in front of the rear tyre which would have passed some heat onto the tyre.

However, I do tend to check tyre temperatures at fuel stops, and at no time would it have been over 60 degrees C (the temp at which you cant really touch it with your bare palms for more than a second or so).

I can't see that poor tracking has anything to to with it, as on a bike, incorrect wheel alignment does not "scrub" tyres as it does on a car .. besides, I checked the alignment many times during adjustments to the chain, which was fine.

However, lets not loose sight of the fact this is a "T rated" tyre, which should be capable of max speeds of 190 kmph (118 mph) ... something I assure you the Transalp is barely capable of reaching.

The tyre was built in 2015, so was not an old one, and while it might be a case of faulty manufacture, if that is so, then I suggest Heidenau have some major quality issues across their range. I'm more inclined to say its operating on the limits of its design, and perhaps a more cautious description of its capabilities is whats needed.

Another also had lots of cracking.
I got 30,000 km out of my set of Heidenau tires and had one puncture.
They went though the Pamir highway and Mongolia with only one puncture , only happened on a gravel road though a crack and sharp large stone I reckon.
Plugged it and did something like another 2000 km before I put a tube in it as the tire was too bald for plugs to stay in very long without losing air.

I'd also just like to add that after approximately 8000km on my TKC80's they're done for. Spain to Mali via Guinea. If I could get even 10,000km from a tire now I'd be stoked. The k60 will for sure be my next tire.

Are you sure 35 psi is not too high for those tyres?
Never had K60 yet but I never inflated my tkc80 more then 25psi and they lasted over 20 000 km.

Back in 2014 I rode from Serbia to Japan ...24.000 km on Haidenay K-60
Highly recomended to adventure riders....as I used onother set for my trip acros Central and South America and they lasted 25.000 km.

Hi,

I've just finished riding my K60 Scouts for 7000 miles, mainly on the road with some off road and green laning.

I found them to be excellent tyres, but poor in Mud (which we have a lot of in UK).

I dd get some crakcs / cuts in teh tyre after aggressive riding on dry stones. This was not unexpected as they are "softish" tyres. remember its a 50.50 tyre and hard off road will not do it good.

Happy traveling and thanks for posting your story - always interesting to hear experiences.

Add me to the list of people who experienced pronounced cracking on a K60 Scout rear.

I fitted them to my XT660z last year and rode from Cape Town to Nairobi - a mix of tarmac, gravel, dirt and the odd bit of sand. Overall I liked the tyre and after 12,000 kms or so there is plenty of tread left but the cracking was a bit disconcerting. Based upon this thread and comments i've read elsewhere I am working on the assumption that the cracking is an unwelcome feature of the tyre.

Russ, your conclusion is very understandable from your point of view. However, please bear in mind with other tires wouldn't even make it to Thailand.

Wauschi
