A flooded pothole is far worse than a dry one because you cannot judge the depth. The town sits where four rivers meet and the crossings and low lying lanes collect water, so after heavy rain a road can look like a puddle and be a six inch hole. Hitting one at speed drives the rim down onto a hard edge with the sidewall trapped in between, and the water offers no cushioning at all. The usual result is an impact break: casing cords crushed and broken from the inside, with nothing visible on the outside.
The tyre then holds air, sometimes for weeks, and fails later without warning. That delay is what makes it dangerous, because by then nobody connects the two events. If you have hit something hard through standing water, it is worth having the tyre and the rim looked at rather than waiting. If one has already gone, ease off the carriageway, put the hazards on and stand back from the tarmac. A burst casing cannot be repaired, and we bring the replacement to wherever the car has stopped.
A blowout on a quiet street in Hertford Heath is no different from one on a motorway shoulder in the way that counts: the tyre is finished and the car is going nowhere useful on it. Level in Foxholes, sloping in Hartham: we set the car straight first. Underground parking in Bengeo or Sele Farm is worth flagging.

Hertford grew up where the rivers meet and the low lying crossings and lanes hold water after rain, so flooded potholes are a genuine feature of driving here rather than an occasional nuisance. The damage they do stays hidden and surfaces later, often on the A414 or the A10 where there is no room for it. That is the case for looking straight after the bang rather than weeks afterwards.
A driver on a low lying lane near Hertingfordbury hit what looked like standing water and was a substantial pothole. The bang was heard and then forgotten about for three weeks.
A car in Bengeo developed a sidewall lump some days after a hard hit through water. The cords had gone at the moment of impact and the rubber gave way afterwards.
A vehicle near Ware Road had both a damaged tyre and a fold in the rim edge from the same impact. Both needed dealing with before anything would seal.
Because you cannot see how deep it is and the water gives no cushioning. You hit the edge at full speed with no chance to lift off, which is exactly the condition that breaks casing cords.
Damage where the sidewall is crushed between the rim and a hard edge, breaking the cords inside. The tyre often keeps holding air and fails later, which is why it catches people out.
Look for a bulge on either sidewall, including the inner face, and check the rim edge for flat spots or scuffs. Impact damage usually leaves marks on both.
After a hard hit through water, yes. Finding a bulge on your drive is far better than finding out on the A414.
