i replaced my front tyres recently with michelin pilot sports not more than 3 weeks ago and the left side tyre is chewing up very badly compared to my right wheel, tracking was done with my tyre change inflated to correct pressure. the only problem which i have noticed is when i turn right hard it feels like the left wheel is slipping off and make a "thump" sound as it goes. Anyone know what this could be?? Think its time for vectra to go its given me nothing but trouble
