Wheel vibration at 70-80 mph

[Ads1982]

Hi the v6 has four new tyres,has had hunter alignment and wheels balanced,but there is annoying wheel vibration and lack of feel at 70-80.Is this any known things too look for or the v6 or would a knackered wheel bearing be the cause.
Thanks Al

...and this is why we trust in SGM to commission such work and road test afterwards.

I'm not sure what to say otherwise ADS. If it ain't right, then there could be several permutations of cause.

Did it vibrate at this speed prior to having the new tyres fitted?

Good question

Does it go away after 80 and beyond, my first guess would be balancing. If you can drive through it I.e 80 - 90 (on a private road of cause) it will be balancing

Id go for the balancing. Faulty wheel bearings make noise rather then judder.. generally. It is possible who ever balanced the new tyres got the weights stuck in the wrong place
