I've constantly been having this problem since I got this car four years ago: The outside of the front left tyre wears down significantly before everything else. I've got the tracking (alignment) done when changing the tyres the last two times, and March 2018 was when I last changed the front tyres. I've done about 11,000 miles since then, and the centre is down to around 4-5 mm. Should I be checking the tracking more often, or should I just go to a different tyre shop? Or is there something else wrong? Also not impressed with all the cracking on these tyres after less than 1.5 years (Goodyear EfficientGrip Performance).
