Well, it all depends, right? Is the wheel and/or wheel-lip bent inward at all towards the hub? If so, this guy would toss it; it WILL affect the tire's ability to hold a seal at speed. However, that doesn't look like that's the case at all. Correct me if I'm wrong, but it appears the outer part of the lip itself is bent just a tad outward and the base of the sealing lip (where the inner most part of the tire seals and contacts the wheel) looks to be in-place and unaffected, yes? If that's the case, you SHOULD (like 98%) be fine. Just please, for the love of God, don't go whacking at it with anything unless you've got some serious heat on the areas affected. There's a really good bench-vise fix for something as simple as that. You don't have a dial-indicator, do you? A little creativity and you can get that thing damn near perfect. Keep it, fix it and ride it!
