A bulge is not a slow puncture and cannot be inflated back into shape. That misunderstanding is the one we correct most often, and it matters, because people carry on driving with a swelling on the wall for weeks thinking it is a pressure problem. It is not. It is the casing cords underneath having snapped, usually in one impact, with nothing but air holding the profile. The second misunderstanding follows close behind: that the sidewall is not the part touching the road, so it cannot be that important. The wall is the part carrying the whole weight of the car and flexing every revolution.
The third is the cheerful one. Plenty of tread, therefore a good tyre. Tread depth tells you about grip in the wet and about the 1.6mm legal line. It tells you nothing about a cut that has reached the plies, about crazing that has hardened the rubber, or about a wall pinched against a kerb months ago. So we look at the whole tyre, on the car and off it if that is what the question needs. Sometimes the honest answer is that the tyre is sound, and then you drive away with the one you already had and the money still in your pocket.
An MOT advisory about a tyre is a warning with a date on it. We can look at the car where it sits, in Hounslow Central or Hounslow town centre, and give you a straight view, then fit the replacement there and then if that is what it needs. Old tyres leave Heston, Lampton and TW3 with us, every time. You watch it happen in Lampton, or at the kerb in Cranford.

High kerbs, tight bays and constant stop-start work around Hounslow town centre make impact damage the usual reason people ring us about this. We come and assess the tyre where the car is, explain what we can see, and fit nothing at all unless the tyre has genuinely finished.
Only visible from underneath, which is where most inner-wall bulges hide. The owner had noticed nothing through the steering. That tyre was replaced immediately, because the failure when it comes is sudden and rarely at low speed.
Squeezing into a bay on the A315 had taken a curl off the alloy. The tyre beside it, though, had only surface marking and no crease in the wall, so it stayed on the car. A scuffed wheel does not automatically mean a scrapped tyre.
A car used for short local trips had four tyres with tread to spare and walls covered in fine lines. Age had done it rather than mileage. We explained the trade-off and let the owner choose the timing.
No. There is no safe speed for a broken casing, and heat builds up in the damaged area precisely because it is flexing more than the rubber around it. Get the spare on or leave the car.
By depth and by what is showing. Surface rubber marking is cosmetic. Anything exposing the fabric or steel underneath ends the tyre's working life, and that judgement needs a close look rather than a phone description.
Sometimes. Bulges and cuts are readable from outside. Impact damage to the inner wall, the sort you get from a pothole, often is not, and then the tyre comes off the rim.
Maybe, maybe not. We will give you our own reading of each tyre and tell you which ones can stay. Being told nothing needs replacing is a perfectly normal outcome of one of these visits.
It can be. Hitting an edge hard enough to mark an alloy pinches the wall between the metal and the kerb, and that pinch can break cords without leaving much of a mark on the outside.
