buckled wheel help
In need of some help/advice here
I bought some second hand 15" 195/50/15's the other day. I decided to get them all balanced today. First wheel was 120 out, second being 130 and third being 135. The bloke at the tyre garage fitted weights to them and got the machine to read 'OK' What worries me is im off this week and have to take my daughter to school (9 mile drive) are these wheels ok, does buckled mean they are totally shot or can a few weights repair them? Any help would be great as I have no idea about wheels and really dont want to be driving my car if it could be dangerous.
Thanks in advance.

Not necessarily.
You can have a set of tyres on one wheel and need only 10g of weight, yet swap it to another wheel (even a brand new one) and suddenly require 60g+.
The tyre "adjusts" itself (for want of a better word) to the wheel it is fitted, so subsequent swapping can affect it.
You can try moving the tyre around the rim in 90 degree sections until you find a setting that lowers it, then weight it from there.
I have had it with a set of tyres, took them off one set of wheels and put them on another set, went from 30g weight to 90g
and when I put a new set of tyres on, went down to 10g-20g average and one actually had none 
.
Also, depends on what type of weight you are using and the placement. Outside-fit "bang-on" weights will take less to balance a tyre than alloy "stick-on" weights. They need twice the amount due to where they need to fit on the wheel.
If you are really worried, I would spin the wheels up with no tyre on and check for hub-warpage (whole wheel wobbling sideways) and for run-out (wheel moving up and down). If you need more than about 10g weight on an alloy with no tyre or weights on, then the wheels is classed as buckled.
