Landed PA28 at Bristol, funny rumbling noise from the front and lots of vibration from the nosewheel, plus seemed to see more of the runway than usual. Keep nose raised as much as possible. Tower confirmed it was flat (do they have binoculars?) and told me to stop the engine and stay put (on the runway).
Large yellow fire engine comes tearing up the runway followed by landrover. Fire engine sprays foam on the grass (apparently they build up the pressure on the way out, and have to 'release' it whatever happens). Everyone quite excited and very friendly. All commercial traffic held up. We all pushed a/c off the runway, and found only one bolt (no longer) holding the two nose wheel rims together.
Felt embarrassed and lucky at the same time, plus probably received the best ever value from a landing fee.
