I have blue earth on my daily use car Baleno since January 2018 and have driven on them for 12k km till now. Ride is very comfortable. Not very noisy. Absorb the shock well when drive over pot holes or cat eyes. Only one puncture but it was because of a very sharp twisted piece of metal.
No experience on driving on highway as I don't take that car on long route.
Would recommend them for driving within the city like Lahore and Islamabad
I purchased them from J. RASHID Neela Gumbad Lahore.
