On recent trip to Bijapur, the early morning drive from 6AM to 10AM [~200 km]; maintaining 70-90 kmph, MID showed FE of 23.2 kmpl.
Later part of day; the FE dropped so the overall trip it showed 20.4 kmpl
Car second sets of boots did not last long and 2 tyres have worn out flat [least is 1.5 mm]
3rd tyre has got damaged due to stone on the thread face. Can take risk running in city and not on highway.
Reported to MRF and they inspected my car & reviewed it.
I had a big concern whether there was mechanical issue on the car; MRF team ruled out.
Finally concluded that right from the time I put on the second set of boots - there was an issue with alignment check. Front Camber each side was extreme on either sides; this has affected the Toe setting and resulted in more tyre wear.
Finally claimed it is due to the alignment issue or more towards the calibration of the alignment machine.
I used to get alignment done outside Nissan Workshop; expecting they do better job - alas it turned out to be wrong.
Recently checked in Nissan Workshop and figured out that the Wheel alignment calibration needs correction too.
Finally replaced the tyres to Good Year Efficient Grip SUV.
Shall post pics shortly.
