I have a worn ring on the inside of my front passenger side tyre - a bald ring withing about 10k miles, whilst the rest of the tread is approx 5mm. I thought this was the tracking but my local indy tyre place has said its the ball joint on the suspension arm that's causing this.
They checked the price for a new one and its app £200 + vat as the suspension arm only comes in a whole unit.
Does this sound right re the tyre wear? I have my mot in a week or so so I need to get this sorted asap,
