    Does anyone have pictures of the early wheel weights that were revited on ?

    My friend is restoring an early 50s LeMans car and it looks like the wheel weights were rivited on to the alloy wheels,

    Was this a common thing ?

    THanks for any info

    I've seen them laced around the spokes of wire wheels but never riveted on. Others?

    I have never heard of that before. Usually it is the tire that is the cause of the imbalance. Would they re-rivet new weights on for different tires?
    The brake drums will have steel weights screwed or riveted to them to balance them.

    If you look at something like a Lancia Aurelia wheel from the early 50's, you'll see that the wheel weights are to be attached to studs permanently mounted on the inside of the rims. There is a complex procedure detailed in the workshop manual for balancing these wheels.

    I would think that riveting a weight onto an alloy wheel would be a great way to start a crack in it.

    The early Borrani rims were rivetted together rather than welded as they were later. The ends of the rim were butted together and a plate rivetted on top. Perhaps you're mistaking this for a weight.
    I don't know what year they went to welded rims, but think it was just post war.
    I'll post a photo if I can find one.

    thanks for the info ,

    its a steel center with an alloy outer , not a Ferrari rim ,

    My friend just assumed that was the way things were done in the 50s as they did not think of glue on weights yet,

    Type of car?

    Are you saying that the wheels were put onto a balancing machine and marked, then holes were drilled, and weights were attached with rivets? I find that very unlikely. Do you have a picture of the wheels as described?

    Dave, are you saying that a rim with a steel center and an alloy outer is not a Ferrari rim? Or, are you saying that your friends rim has a sttel center with an alloy outer, thus not being a Ferrari rim?
    Either way you are wrong. Ferrari wires have steel centers and alloy outers. At least every one I have seen.

    No mention of "wire wheels" in the original post.

    Well he did comment on the hub and rim so I assumed he was speaking aobut wires. Were there complete alloy wheels in the fifties without wires?

    Hallibrand in the USA. Campagnolos alloys date from the 50s too.

    Certainly.

    There was no mention of Ferrari, only "an early 50s LeMans car".

    Is it anything like this? These rivets are for joining the alloy rim to the steel center, not for attaching wheel weights.

    Picture from the "Illustrated Porsche Buyers Guide".

    There are enough examples out there of Borrani's with a steel centre and alloy rim from the period. Ferrari's first complete chassis had them, and 015/s (?) had knock-off disk Borrani's.
    There must be plenty others.

    I cannot for the life of me imagine a riveted on balancing weight, it makes no sense.
