hi all went fri to ats tyres on fri as i had a slight vibration on the steeering at about 30-40 mph and also it was pulling to left so he balanced to 2 front wheels and said the tracking was out by 3degrees so put that right. after driving it a fair way yesterday still seems to be the same with one difference the streeing wheel not in centre. so took it back to a different ats tyres told them he put the wheel on the machine and said the tyre was out of shape did this on the other 3 and said they was out of shape 2 was quite bad and 2 not so bad. is this possible and said i need 2 new tyres they are 195/80/15 goodyear wrangler tyres i have on there on alloy rims. many thanks
