Hello, in advance, I think I drive 80% BAB and have increased the tyre pressure a little bit and have 2,8 and 2,9 bar in the front. I notice the consumption already a lot if I have the 2,2 bar of the vehicle or mine on it. I got this tip a few years ago, 2002 was I think, in a driving safety training. Now it was that 2 years ago my tyres became very loud and I already speculated it on a wheel bearing damage, but then I was told that it was a sawtooth pro I took it that way and was logical for me. Then there were a few new ones, they were due anyway and at the back I had to bite in the sour amp and pick up so new ones. After 2 years the whole thing started again, but this time the car went away 😉 Now an acquaintance has been on the BAB again last year, about 35t km also with about the same pressures as me and this sawtooth has formed. Sounds like a trecker already. Now the tyre dealer said it would come from the too high air pressure and not from the, I say driving way. Maybe one of you can help me… Greeting Gregor
