New tyres on the Subaru last week. While they were working on it they said that there could be a problem undoing one nut and could break a stud. (Subaru problem so they say) Take car home notice slime all over the wheels. Check wheels and see scratches and rash marks all over them. Previously they were scratch free. They said they put 36psi in them which is correct. Checked them the next day cold and there was 41psi. After driving 100kms I like to check the tension on the wheel nuts. Tension was close but noticed a wheel nut missing and a broken stud. I shouldn't have been so lazy and just driven to Sydney to buy tyres.
