Front wheel vibration

[Joey Shabadoo]

Did a quick search but couldn't see anything - my front wheel has developed a vibration, like I'm going over a bump once per revolution. It's quite noticeable and I'm a bit worried cos I'm going on a long (for me) organised ride on Saturday. I've just swapped back to 32c Gatorskins from my much fatter cyclocross tyres so I'm not sure if they're the problem or if the fatter tyres were absorbing the wheel vibration before. Hub is tight, no wobble and the wheel seems pretty "true". Anything I'm missing?

Vibe on the road, or in the air (bike lifted). On road will be a tyre issue, in air bearings. Also lifted, could be wheel trueness.

Maybe a bit too obvious but is the tyre seated completly into the bead?

Your tyre might have a bulge.....

Tyre seating doesn't usually cause this, unless you've made a big mess of it, like it will pop off rim...

Thanks all - the tyre hadn't seated properly at the valve, leading to a slight bulge. I've reseated it and gone around the block, seems to be ok.
