    Default My wheel measurements for replacements

    There's not a lot of wheel companies listing wheels for the Volt yet, so info on the wheel specs is limited. I went ahead and took my own measurements just now and this is what I found.

    Can anyone confirm these measurement? WOT?

    1) Total weight of wheel + tire + tpms + centercap = 37 lbs

    2) Bolt pattern = 5x110 using http://www.americanracingwheelsinfo....lt_pattern.htm

    3) Wheel height measured which includes the flange height = 18" per http://www.procarcare.com/icarumba/r...dia_wheels.asp

    4) Wheel height estimated by removing the estimated flange height = 17"

    5) Wheel width measured which includes the bead seat lip = 8" per http://www.procarcare.com/icarumba/r...dia_wheels.asp

    6) Wheel width estimated by removing the estimated bead lip = 7"

    7) Offset = +37mm per https://www.rsracing.com/tech-wheel.html

    These numbers look a little different from what I read elsewhere, especially the 5x110 versus 5x105 bolt pattern, so any confirmation would be appreciated. I did measure several times to check and recheck my numbers.

    I am looking for 18" rims that have a more aggressive look while still being modern. The styling of the Volt can definitely manage a more radical wheel -- as shown by the Ampera concept. Maybe a little more offset (wheels more out), but not a lot.

    Maybe something like this:

    I am pretty sure the 17" diameter and 7" wide is correct, especially since the 17" is listed as the tire size. Not sure about the bolt pattern though, and that has to be exactly right. The only way to measure it physically, is to measure the distance from the center of one bolt hole to the center of the rim with a metric caliper and double that to get the correct diameter of the bolt circle pattern. It should be listed in the owner's manual, but may not have been listed there.

    Possibly a Volt advisor could find out if they can talk to the engineers that designed the car.

    voltage692,

    I may be interested in the stock wheels and tires?

    Several months ago someone with a line into GM posted the exact wheel specification. You should be able to search and find the specs in the archives of this site or site FAQ linked in my signature.

    Sounds good. As soon as I find some good replacements, I will contact you.

    Did searches, but couldn't find anything. Any ideas on search words from what you remember of the post?

    If there is demand for the stock wheels and tires, then I may be interested in downgrading to 15" or 16".

    Then again, just the other day I saw something about the Volt's wheels being specially designed for low air resistance, so I would have to take that into consideration. (After that I went outside to check if the wheels, which are not symmetrical around the axis of each spoke, are mirror images on the left/right side of the car. They aren't, which seems odd if they really were designed for low air resistance, unless the asymmetrical bit is for style only.)

    Yea, that's called marketing.

    Here's a horrible job at photo editing in Paint.NET. It would be nice if I really knew how to use these programs.

    I saw the claim on a television documentary. (http://www.youtube.com/watch?v=jP4D_zk4zdM#t=17m52s)
