I have read so many good reports on the DTM and I was sold on them. I was running Metzeler Karoo 3 on my R1200GS 2017 and found the noise on road irritating. All reviews on the DTM says the level of noise is lower than other equivalent tyres, esp the Karoo 3. Also, everyone seems to report the noise comes from the front and is amplified up the front forks in the R1200GS making it worse than other bikes. The DTM rear tyres on not in stock in Australia until 2021. So I decided I would just swap the front. So I now have the DTM on the front and the Karoo 3 on the back. I have to say the whirr between 60 and 90 kpH sounds like a jet engine taking off. I tried coasting in neutral at this speed and leaning forward and backwards to try determine where the noise is coming from, and I am thinking it is from the rear, and not the front, which contradicts what everyone else finds. I am also thinking that tyre manufacturers in their trials and testing (incl Dunlop) would desing the tread patterns that the harmonics do not amplify, but rather cancel each other out and hence, one should not mix brands of tyres. My question is, and hopefully someone will know - Should I wait until the DTM rear becomes available and fit it on the rear in the hope of this horrible noise disappearing or reducing, or just change both out to a different set? (If I cannot resolve this noise, I will have to go to 90/10 and forgo any riding on unsealed roads, as I do most on road). Anyone else had a similar experience?
