It sounds like I'm running on a flat!!!

[IWC]

My vectra is occasionally making a noise from the front after cornering or heavy acceleration. The noise sounds like one of the front tyres is flat?!? Its clearly not got flat tyres!!!!!!!

It does not happen all the time but it is becoming more common? Could it be the wheel bearing?

[Exclusive BV]

sounds like it could be a bearing but normally they are noisy all the time or when steering a certain way.

What sort of noise is it?

[IWC]

it sounds like a flat tyre at low speed, its like a soft thud.....thud....thud....thud!!!!?

Worn bearings on the Vectra C don't make any noise, makes them difficult to diagnose unless you have the car on a ramp

[Caveman_nige]

have you got a flat spot on your alloy rim... best to get it checked out

presume you've nothing stuck in your tyres ?

is braking system ok?

[IWC]

braking fine, alloys fine & no nuts, bolts or stones in the tyre! ? ?

A long time ago I drove over something that gave an occasional banging sound from the nearside front tyre
Initially I couldn't see what it was, so drove forward such that I could inspect each third

I found a large split elastic band wedged in one of the treads!

If you suspect the tyres, then post a little more info, including make, type, profile, mileage / age per axle

sorry if this is real obvious,

are all wheel nuts tight? and torqued to correct rating ( 110nm i think )

just wondered

also are wheels catching anything - cables etc anything loose under wheelarch ?

Don't they, do they turn red when they need changed then

Thats a fair point to make and anther thing i'd be looking at are the driveshafts
