We had our 2021 NX put in for service at beginning of the year and it turned out it needed 3 new tyres! (One had nail in non repairable spot, the other two had holes down to wire??) Anyway, as in for a service, I agreed for Lexus to replace the 3. We went for same as it came with, 3 x yokahama's. Plus the tracking got corrected.
Since then, the mpg has been back up to over 40mpg every trip.
I think yokahama are just fine. Car is, as always had been, smooth and refined (but now with better mpg again 😆)
