    I have had rims repaired with damage like that.... but it is impossible to say until the tyre is removed and fully examined for cracks and other damage.

    Once the tyre is removed take it to a specialist wheel repair shop for their advice.

    They should be able to press the dent out and possibly die check (or x ray) for cracks.

    Not sure I would feel comfortable driving my high dollar ferrari on a questionable rim, Aluminum usually stress cracks or breaks when being pressed back into shape.Just my 2cts

    I would call a local high end rim or machine shop and get their opinion. Bad luck :( same thing happened to my dad in his Mini Cooper S. Runflat got a bubble in it and had to be replaced.

    I honestly can't see the damage. Maybe it's just me, but check out the damage. EDIT: Never mind :eek: I see it.

    Is that a Triumph TR6 behind the flatbed? Yours, or a concerned Samaritan.

    It's an 80's era MGB. Is that your other car, or a sympathetic friend for a ride home?

    That is really a shame.
    Ther are wheel guys who can "unbend it" but do you really want to drive on a tempered alloy rim.
    By the way where did u do this in NY. I'd hate to hit that same pot hole.

    Sorry to hear of your bad luck.

    ...but those MGs can be a blast with the V8...it is not a GT though its a MGB (GTs had no convertible roof...just a hatch back)...saw one recently with a Holman and Moody 289 shoehorned into it...crazy fast too!

    As a Mechanical Engineer I would suggest buying a new rim. Bending it back cold, or heating it up to soften the material to reforming back to its original shape will make it look fixed, but not worth the risk if it did develop stress cracks.

    The issue isn't the spoke so much as the outer seal of the rim itself. It's out of round now and chances are any effort to bring it back to its original concentricity is futile. You will most likely have vibration issues due to the weight imbalance during high speed rotation.

    Just my 2 cents.

    I am also a mechanical engineer and agree with MJT replace the rim, a previous poster suggested dye penetrant for crack detection but unfortuantely this would not detect cracks under the surface. It is just not worth the risk 0f ever using that rim again.

    Agree die penetrant will not pick up "interior cracks" but, a one time over stress of a part will generate "external" cracks, unless there is an inherent flaw in the casting.

    The part should be thouroughly checked by somone experienced in repairs etc, before a decision is made on if repair or replace is the way forward.

    Good luck

    You are right. It's an MGB.

    I'm an ME also. Replace the wheel. Cast aluminum wheels are not meant to be repaired. Think of it this way. Even if it's marginally acceptable strength wise this time after repair, what will happen next time you hit a pot hole at high speed? Would you prefer bending your new replacement wheel or have your repaired wheel fracture and cause a major shunt into the guard rail or lamp post?

    Salvage the old wheel by making a coffee table out of it, so it's not a total loss. :D

    If the only damage is that outer lip maybe, but the challenge wheels are notoriously not strong.

    I'd opt for a new rim eventhough the cost will hurt.

    Not to minimize your loss, I've been looking of a nice irreparable Ferrari wheel to use as a hose reel. :)

    Yet another mechanical engineer - I say replace it.

    How many engineers is that now? We gotta come up with some sort of joke about how many mechanical engineers it takes to tell you to replace the rim....

    By the way, I think the challenge wheels are magnesium.

    This was recently posted on Fchat ads.
    BTW, It's not my ad.

    2x brand new wheels, 1x front 1x back.

    5 and counting....

    If we get the another we might have enough to figure out how to replace a light bulb. LOL

    Sorry, not an engineer, but did get 3/4 of the way through a metallurgy degree, does that count?..... :)
    Can we change that light bulb now…..

    I see the general consensus is to replace the rim without inspection.... ok that is probably the easiest thing.....

    While you are replacing it, because the forces have been transferred equally through all unsprung parts of the car probably best to change:

    1. Wheel bearing
    2. Stub axel
    3. Upright
    4. Hub
    5. Wheel bolts
    6. Shock absorber
    7. Upper and lower ball joints
    8. Steering rack and tie rod ends
    9. And all mounting the bolts….


    When I bought my car it had hit a kerb, the tyre was US but the wheel looked undamaged, I x-rayed it anyway, no faults were found, but this was the upright.
