Places that specialise in tyres generally do it, and so should most garages. Don't let them try and quote a price on anything else though as some places may have job targets.
And yes, its most likely the tracking.
' If a wheel needs tracking it should be 5 pound per wheel' ?? That doesn't sound right to me dude.ok doing this for a living only if a wheel need re tracking it should be a 5 pound per wheel get some on to look at tyre wear first then re balance the wheels before they do the tracking also look at tyre pressure as well and use a good place as i now track rods on my car were nackerd
