    Can you post a picture of the lug nut hole in the wheel?

    You know, it almost looks like someone oblonged the holes to fit a different bolt circle. Is there any evidence of that? Do all the holes look exactly the same? Any evidence of file marks on the insides of the holes?

    it looks like those lug nuts would work fine. It looks like the rim is cast with an oval opening in the back and the front is drilled for the exact bolt pattern.

    This is a slightly different unilug set up than the one on my Keystones. My rims have an oval slot and a wider oval recess on the face of the rim. You place an offset washer in the recess and the lugnut passes through the washer and the oval slot. I like the daisy design better.

    Artificial enlargement of wheel holes, hm? Doesn`t sound too nice to me. Ok, you`re really helping me out with this, please give me some more info. I`ll take some close shots of the holes, front and back and you let me know what you think, ok? Also, I`m not familiar with the unilug wheels (not too common around here), what kind of washers and lug nuts to be used on my wheel, I even don`t know what to order from Summit, so please keep feeding me with infos, I really appreciate it.
    Also I could imagine that they might be up to vibrations, read about this. A common issue?

    i would suggest that u contact the manufacturer and if the holes are ovalled for unilugs, then purchase the correct lug nuts from them.

    There are a couple of items that are critical in getting these wheels safely mounted. They're pretty obvious, but it's easy to get it wrong.

    The base of the lugnut must match the seat on the rim. Some lug nuts are flat where they meet the rim, others are conical. It looks like your rims need conical seats. There are probably multiple angles of cones, you want to find the one closest to your rims. Perhaps someone here knows the appropriate angle for your rims or knows how to measure the angle.

    The lug nut must not press on anything other than the rim. It must be deep enough so lug nut presses the rim against the hub. Some lugs have a shaft below the nut portion that reaches through the rim. If they reach the hub the wheel will not be properly secured. Some lugs are longer than others and you need to be sure the top of the lug doesn't bottom out inside the nut.

    I would think you could take one of your rims to a shop that specializes in aftermarket rims and find someone who can point out the right lug nuts. They usually have a wide range of lug nuts available for the different rims they sell and you can test fit a handful to find the best.

    Good Luck,

    John

    Hi ,

    thanks for all your comments on the wheels. I`ll see if I can find someone who`s a little more familiar with the unilugs than I am. Still I took some pics for you guys to check on the holes and maybe give me an advice of nuts that might work, promise I won`t bolt them on blindly and afterwards blame you folks for giving wrong advices. By the way, I don`t think they are bored over or enlarged, they show no signs of manipulation other than being driven in the past. Is the usual size 17/6? Any problems with unilugs creating vibrations under heavy acceleration?
