185/70R14s also fit, but they can cause strange handling issues on a 'B unless you have wider than stock rims. But if you only need the one it would be best to see what can be done

If you do go with 165R14s I know of a place that can supply and fit them for £42.50 a corner. He can also balance and seal wires.
