Ceat Tyres — tyre grip & stability

Address:

411040

I buy a two wheeler ceat tyre on 9 may 2018. Afterwards it’s been little shaky from both front & rear tyre. I checked with the dealer but they said it just because of new tyre which will ok after some days after using.
Because of tyre my bike is continually shaking while my speed is nearly 30-40km.

After 5 months i am still facing the problem of shaky ride all the time.
Hope you will resolve my problem asap.
