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
