On a CRV, two tyres ending on a C and two on H?

Question from visitor, 08/08/2014 :My local Honda dealer fitted 2 rear tyres FOC. They have fitted tyres ending in a C and I've been told that they are for comercial vans and not a CRV. While this might not be illegal are these tyres safe and reliable to use when the front tyres are for cars and end in H?

Hello,

Thank you for your question.

Can you please specify the dimension of your tyres as well as the model and the engine of your car?
