we were out at the flics tonight (at Linwood for the locals), the easy way home by motorway was closed for repairs, the detour taking us round the arse end of Paisley and back towards the airport to rejoin the M8. trying to follow the detour we didn't spot a bit of pavement sticking out into the two lane road - like a reverse bus stop, so bang! both passenger side (near side? never did get the hang of that) wheels collided with the kerb. both stayed inflated, no wobbles or pulling on the move, but there is a bulge on the sidewall of the front tyre. about the size of a tangerine, but black ...obviously.
my question (at last I hear you cry) is this - does the bulge mean that the tyre is damaged and unsafe? (would be typical as they're not that old)
