You need an alignment.

At that speed you should stop drinking. You will spill your booze.

wheel alignment or wheel balancing or broken/missing bushing.

Thanks guys, your right. while jacked up I swapped the wheel for the spare cos I noticed a bulge on the tyre. I doubt it's been balenced.
It's also been pointed out to me that to correctly put the wheel on, there should be a mark on the wheel stud onto which you place the wheel hole nearest to the value, I'll check tomorrow.

The bulge in the tyre could be a snapped steel belt. It's happened to me before. At speed, it produces symptoms very similar to unbalanced wheels/tyres but it tends to be a little more severe. A good way to test is to drive very slowly (say, 10km/h or 6mph) and see if there's a perceptible tug on the steering wheel. If that's the case, my bet would be a busted steel belt. It's likely you will need to replace the tyre. Balancing the tyre may reduce the vibration but it probably won't eliminate it.

there wasn't a problem when the tyre with the bulge was fitted, only now with the new spare. It's not a huge bulge, just bigger than a coin but can be dangerous & cause a blowout so i swapped it.

the faster you drive the more you should spend on an alignment.

The usual $10 Kmart "alignment" guarantees that your wheels are generally pointing in the same direction and will probably be OK up to 55mph/90kph before the wheel is ripped out of your hands.

If you go faster spend more at somewhere you can take the car back to if you're not satisfied.

here in the uk i'v never seen anywhere that does cheap wheel alignment. it's generally about £20, but i guess a big garage is likely to have better equipment than an independant one.
