After a while I noticed that my new wheels didn't seem quite balanced right - got a bit of vibration around 60mph.

Couldn't be bothered to take them back where I bought them - got a company just down the road from where I work to balance them. It made the vibration worse right from 50mph up and def bad around 60-70mph. So they had a 2nd attempt and got it as good as it was before I went to them - the steering wheel wobbles a bit at around 60mph and noticeable vibration from 50mph up.

It seems like they're still not balanced right to me but the tyre place bloke was telling me they'd just had their machine calibrated it must be something else etc etc. So what else could it be? If I get lexus to investigate then I guess it's going to cost me lots of money. I have cheap and nasty tyres - khumos. Could this be the problem? Or wheel bearings, warped disks or something? Or am I just being fobbed off?

Although unlikely to be the cause of the problem.. have you had your tracking checked since fitting the alloys..

yeh, agree get the tracking / wheel alignment checked..

Done by Lexus just after having the alloys fitted. Hmmm....

just a guees, try swopping the wheels round, move the front to back n vice versa, see if this helps, it could be a slight buckled alloy..

But they're only a few weeks old and apart from two very slight scrapes against the kerb while parking they're knock-free. Unless they came faulty? Hmmm.

Hmmm perhaps worth a try swapping them though as it would show if it is a problem with a wheel or not.

Thanks.

if it was buckled alloy surely balancing the wheel would correct this???????

Just that not all garages tell you this or they don't pick it out..

Same thing happend to one of the alloys on my previous cars, went to Gorden Tyres (reptutable company), got the balancing checked and re-done, but the steering was shaking was still there but only slightly, but vibration was there too.

I then went to garage where i got the wheels from, they checked and said the wheel is buckled, they replaced it for free..

check your bushes on the radius arm, if they are warn this may cause vibration. if the car is over 5 yrs old or high miles they may be worn.

Wouldn't they notice a buckled alloy when balancing and wouldn't the balancing in theory compensate anyway? I would have thought swapping them would mean you still get a shake but not from the steering wheel.

If the front wheel is buckled, then obviously the front end will shake, but if you swop the wheels round, fronts to the back and the backs to the front and then you brake then you will not notice shaking at the front, but only slightly at the back..

Tried and tested..

My wheels were doing that to and i kept getting them balanced and it turned out that my wheel in the front was bent and that caused it to shake the steering wheel and shake past 60 mph

my old man brought a brand new set of alloys for his car and he had them balanced so many times and had every thing checked etc etc couldnt get rid of wobble it turned out to be bad casting of the alloy might wana get it sorted so u can take em back if this is the case

surely the weights are there to correct for tyre non-roundness and differing weight around the circumference?

They won't cure the buckle as the wheel will still physically wobble!
