Is there a “proper” way to straighten out the dings in a rim? None of them have stopped the bead sealing but I’d like to sort it slightly as I’m about to fit a new tyre.
Short of any other options I’m going to get the pliers on it with something over the jaws.
Cheers
Adjustable spanner works best ime. Or a vice if it's bent outwards
Adjustable spanner works best ime.
Or use it as an excuse to buy some Knipex pliers as they are even better.
I'd see if the new tyre seals and leave it be.
Best case it doesn't leak just looks bad.
Worst case you try and bend it back and it cracks.

I've got a set, I'd say they're better than molegrips but not as good as a decent aj for this. (specifically, the massive one with imperial measurements on that my grandad stole from the RAF, but other ajs are available)
Rim jibber? Bought or built.
Ah there’s a proper tool! Only available in America though?
I’ll dig out an adjustable cheers 👍
Adjustable spanner plus a metal ruler on outer surface to protect rim and as a bit of a guide to when straight
Shifter. Sounds silly but bring the rim in the house rather than do it in a cold shed. I reckon it's enough to stop cracking on some dings. Although I haven't used a scienceometer to prove this so I'll be wrong obvs.
Yeah the Jibber is only available in the US but doesn't look like a complicated beast, the only real difference is the cutout to hook the rim bead.
I've got the Jibber - the guy selling them is perfectly happy to ship to the UK - although I don't remember spending as much as they seem to be now. It can still dent or mark the rim while pulling the ding out if the ding is a big one but it works well and for smaller dings it's brilliant.
I think there's a guide on MTBR on grinding an adjustable to optimise for rim pulling. Syntace also used to make a rim pulling pliers tool but I could never actually find one for sale.
Took the rear tyre off my FSer last week, as expected, the WTB rim looked like it had been to a pool party with Barrymore. Sorted 4 or 5 big dings, nothing to lose as it's gubbed anyway really.
Hopefully hold out til later in the year, then I'll be getting some decent rims.
Leave well alone if still holding air fine.
You won't see the dings when you're riding.
Anneal the alloy before bending - use old fashioned soap as your guide.
Rub some soap over the affected area - heat it up gently but tightly with a torch (MAP gas is quickest). The soap begins to crust over and look burnt at approximately the right temperature. Then bend out the rim back to shape.
Quench straight into a bucket of cold water.
Done this loads of times forming aluminium alloys, its rough and ready but much better than just tweaking it back cold with pliers.
Might mess your rim tape up though!
Adjustable spanner worked well cheers 🙂 All sorted

Quench straight into a bucket of cold water.
That's not annealing.

No, but the bit before that more or less is.

Depends on how low the bucket is. You might do it annealing or astanding
