Very interesting Fred this!

I put an E07 on recently as there was no stock of Scorpions and I was going up and into Lesotho. Have no regrets so far and am loving it! There are a few small chunks out of it, but that's from pulling the ring out of it offroad! ;-)

Did I read correctly earlier in this thread about running or 'curing' a tyre in? I know about the first 50kms or so and scrubbing  any new tyre, but if I recall correctly, someone was talking about getting it up to temp and running  it in?

Or am I PUI???  ???



Edit: Went back and looked. 'Tour' mentioned on page2 that after a few "Heat Cycles" his tyre never saw more than 2bar. Do heat cycles help cure a tyre and make it last longer or something?

There are so many "experts" here I feel totally inadequate and hopelessly outgunned

You guys are so awesome you must get jealous of yourselves

I have done about 50 000 km on a few E07s on an 800GS and SE - fast, slow, rocks, sand, tar, gravel, snow etc - I get great mileage (10 000 km plus out of a rear tyre) and regularly see little hairline cracks but that does not bother me - you will always get that on any type of semi knobbly tyre - especially on 4X4s

The key to any tyre (no matter what vehicle it is on) is pressure - too low and the tyre will self destruct.

I have several vehicles with tyres on (cars, bakkies, land rovers, off road motorbikes, road motorbikes and bicycles ) - I do not use every vehicle every day so I make a point of checking tyre pressures with my own gauge almost every time I use each vehicle - and if the pressure is too low I pump it up with my own compressor and tyre inflator at home - for those who do not have these tools go and buy yourself a decent tyre pressure gauge at Midas etc for less than R100 and check your vehicles with this - the gauges at the petrol stations are hopelessly inaccurate - so after you inflate with petrol station inflator check the pressure on your own gauge.

If you are unsure of what is the correct pressure for you then pump it 10% harder than what the "book" says - your tyres will last longer

Check your tyre regularly for any cuts / cracks / screws / nails / punctures / leaking valves / etc - these can almost all be repaired with plugs etc for very cheap and save your tyres and possibly your life - all it takes is some time and effort

Please do this before you come on to a public forum and voice your "expert" opinion on how shit you think a certain tyre is
JD hit it right on the head. Well put. I removed/destroyed the Knobblies on a TKC80 simply from ridding the rear under-inflated. I didn't blame Conti...it was my own doffness.

Daar is fokkol fout met die tyres nie of miskien ry ek soos 'n girl. I did the heat cycle thing and checked for cracks regularly because of the life threatening publicity this received and nothing. I have done 16000km on my current set with the rear at 30% and the front 5% threat left. (60% gravel) I have abused my front tyre one day we had an advanced training day at the track and is of the view that it might have lasted longer if not for that. Running them at 2.8bar on tar and 2.2bar on gravel. I would like however changing to the Mitas Dakar like the tyre under discussion when I change.

Which is practically impossible under normal riding conditions.

Meaning overload discussions is a waste of energy.

Yes and no

Yes if the pressure is correct.

No if you have not taken the load in consideration. So once again its about pressure. But must be looked at as a whole with the consideration points of load then speed and finally pressure relating to the first two point the greater the first two the higher the pressure. Make sense?

Pleasure...I am just waiting for a result on the tyre analysis...Only problem is to get a definitive they want the tyre back to Europe for lab analysis. However I am due to discuss the issue with the head of quality control and the head of Manufacturing and we can hopefully speed up the process in getting a answer as to the cause of the failure.

I bought a BMW F800 Adventure with Mitas front and back tyre already fitted. The bike has done about 500km with the tyres.
We went to the Hell & Baviaanskloof for a long weekend. I had the first flat tyre at Mooreesburg. We stop at a tyre fitment centre where the guys pulled the tyre of the rim and saw that it had a tear in the side wall of about 50MM.
Having no other choice they repaired the tyre with a patch on the inside and also the tube. We then left for Sutherland via the Tankwa Karoo stall which burnt down the next day.
Long story short the tyre started losing pressure again at Willowmore. (Rony AKA Malletjie) from Jumpers helped us out on Sunday with a secondhand tyre (Not Mitas) and a brand new tube. I was very greatfull! Everybody can definetely pop in there. We had cold beers afterwards and was on our way. Thanks again to him. To get back to the topic. The Mitas rear tyre had 2 extra tears in the side wall on totally different places. We left the tyre with him.
I have got no idea why this would happen?

Does it have this ridge in the middle.
This is my new one. Received today. My E10 is murtu in less than 3,000km.
Am I correct that the E07 that delaminate did/do not have this "centre ridge"?

Sidewall....but what I can't understand is the F800 has a tube so even if the tyre split for some reason (a failure I have never seen before) it would not have effected the tube. The only way you can get a cut in the sidewall and the tube is something cut the tyre and the tube. With regards to the other flat that I would need to investigate further and if you have details of where the tyre is I would like to check?
