After a rear tyre failed (the wall seemed to have sustained damage) I was actually almost outside a tyre shop and had a replacement fitted - not a Pirelli like the others but a Nankang 'budget' tyre as this was all they had on the day. Is this OK to continue using or would it be sensible to replace both rear tyres with a better brand? The car is a Volvo S40 2 litre and the tyres are low profile jobs I think.
