Hello Tafians, I am planning for a 4 thousand Km road trip(both ways) from Bangalore to Jamshedpur in end of May. My car is Punto diesel Active run about 35K with with stock JK tyre. Last service was done at 31K KMs. I have one year baby to travel with me. I am only driver, wife may drive only few 100 kms if require. I have a few question in my mind. Do I need to change the tyres before this journey, as tyre rotation guys advised for this. Do I need to change any oil of car before the journey. Is it OK to drive in highway in peak summer. And feel free to give your valuable suggestions and tips. Thanks in advance.
