I have 3 tyres all with 5-6mm tread left on them and one alloy with no tyre. Tyre was punctured and unrepairable
Should I replace just the one tyre with new one (exactly the same type as the other 3) or should I replace two of the tyres.
Reason for my thinking is, shouldn't the tryes across the same axel of a 4WD car be of the same age/wear. Or will the fact that the other tyres have 5-6mm of tread make no difference if I just fit one new tyre.
You advice appreciated.
