MRF Tyres — tyre damaged

Address:

Guntur, Andhra Pradesh, 522503

I bought a vehicle yamaha fzs in september 2014. Both tyres were tubeless. Yesterday i found that tyres were damaged they look like air bubbles are comming around on the surface of back tyre of my vehicle, i only travelled 22000km in 3yrs. I trusted mrf tyres with respect instead of ceat tyres, but i and my trust both are deceived at the end. Kindly solve my issue as soon as possible
