Honda 2 Wheelers India — Honda tyre replacement under warranty period

I have activa honda 6g model for which tyre warranty is for 3 years ...I had taken my activa for changing tyre in warranty to showroom of activa where they took few picture of my swelling tyre- all over every grip was swollen from inside to outside and it's on the verge of blasting they directed to me to the maxiss tyre dealer without proper information, after that when I went to maxiss tyre dealer he demanded 1200 rs for the tyre change in warranty by saying you have used this tyre for more than a year and the price of the same new tyre is 1400 rs so what am I supposed to do now ?
