Buckled wheel

Just had my wheels balanced this morning and one of them is buckled not to bad
but bad enough,can these be repaired or straightened out.
Cheers fellas
 
Stick the wheel on the rear axle and find the buckle by spinning the wheel, usually the rim is bent in. Mark the low point, remove the wheel and hit it with a big hide mallet. Put the wheel back on and re check. You can also use a tape measure, to see how much it has moved when you hit it. I have done quite a lot over the years, potholes, low profile tyres and big wheels, all contributing factors.
