One of the wheels on my sister's car is slightly out of round. NSR wheel, 18 inch alloy. Had it off the car for a look the other day, there are a couple of small (ca 4-5cm) flat spots on the inner side of the rim (that faces the car when the wheel is fitted).

I imagine she hit a pothole or similar.

You can feel it through the driver's seat when driving, but maoy between 70-75 mph and it's not bad even then.

Could the wheel be straightened, and what kind of place would do it? Or is a good s/h wheel a better option?

The inner rim is always most vulnerable to road defects, because the 'spokes' only go directly to the outer rim. I had that on 19" rims with runflats. I went to a smaller diameter rim. Long term, that may be the best (but costly) option. Could you trust a second hand wheel? It could be best to replace with new. I assume there is no spare.

Personally, I have had straightened wheels worse than that & in person also straightened 2 wheels that were exactly like you describe with no issues at all.

Both served for well over another 2 years in my hands, and had no discernible effect on the car.

The way I looked at it was both were like that on the car when I bought them & had been there for an indeterminate length of time.

When the damage was done it will have been sudden under a lot of load & the wheel did nothing worse than buckle.

When I straightened them it was done gently by hydraulic pressure with warmth in the metal so less likely to produce worse damage.

If you go to wheel refurb/repair places they pretend they use precision state of the art machinery. They don't, they whack with a mallet.

While warming the metal.

Why would you not "trust a second hand wheel" everyone in the country does every mile on every day once the car has been driven out of the dealership.

Do you buy a second hand car & immediately replace all 4 wheels & tyres before leaving the dealership?

Well, the other three wheels on the car are all 10yrs old anyway, so why not?

My concern was not with sh wheel per se, but that you can't really tell from eBay etc whether a given wheel.is straight. So it might end up not being any better than the one she already has.
