P729 Ha scritto:non conosco bene l'inglese ma prova a tradurre questo forse ti sara' utile e' tratto dal libro:mazda mx5 miata : if your car starts vibrating at around 65 mph check the tyre pressures.the mx5 is very sensitive to tyre pressures, and the car will be happiest with 28 psi at each corner.vibration can also be caused by a stiff spot on the tyre where the belts inside the tyre carcass overlap. try a tyre with a jointless nylon band, and have wheels balanced to 1/10 of a gram. these problems are most likely to affetcts cars made before the chassis was stiffened in 1994. to keep your car handling crisply, the shock absorbers should be changed every 30.000 miles. however, some aftermarket items last longer or even offer a lifetime guarantee.

sono passato dal gommista: nel mio caso gomma ovalizzata
appena mi arriva il nuovo wheelset vedo se la vibrazione sparisce o se (sgrat sgrat) ci sono delle concause...
