Experienced that before and a new tyre cured it. Just recently was experiencing it again. The tyre was worn again and I assumed that was the cause. I suppose it is the cause, but after replacement, I still have a very slight oscillation. Here's my theory - The original Metz was a 'LAZAR' the last two where the upgraded version - 'LAZAR TECH'. The tyre is much the same with upgraded compounds I believe. The original suggested PSI was 36 which I maintained. The Metz site fitment chart indicates 40psi. I am going to up the pressure before I get permanent cupping and see if the vibes subside. If there's any marked change I'll post. May not occur till the week end.
