Please, any of you who have received their Bolt or can check one at a dealer, can you report here as soon as possible what diameter the bolt pattern is for the new Bolt EV.

If you can test fit a Volt gen2 wheel on the Bolt and report it will fit correctly, that would be ideal.

There are a bunch of us who wish to order extra wheels and can't until we know the correct size to order.

Thanks in advance.

You can't just rely on bolt pattern as you need offset too. On the other hand, just hold off on new wheels for a year, put a year or two of wear into your OEMs, then buy custom wheels just in time to put snows on your OEMs. Oh wait, you're in Cali, never mind....

I am planning on a set of lightweight autocross ones. But my Bolt is gonna be late. First autocross is in two weeks. Sigh.... :(

The PCD and bore appear to be the same as the second generation Volt. IF they are (5x105 mm and 56.6 mm bore), then the second generation Volt's wheels (and aftermarket wheels) might work on the Bolt EV.

The Bolt EV rims are 6.5Jx17 ET 44, and they provide about 127 mm of backspacing.

The Gen 2 Volt rims are 7Jx17 ET41, and they provide about 130 mm of backspacing.

The aftermarket 7.5x17 rims I've seen for the second generation Volt have ET38 and offer about 133 mm of backspacing.

OK, I rough measured the new Bolt EV bolt pattern, and I am almost certain it is 105mm.
I will test fit one tomorrow afternoon and repost results here then.

Thanks, my dealer tech measured with calipers and said he wasn't positive because he doesn't measure this very much, but thought it was 5x140. Planning on remeasuring locally soon. Didn't get to measure the bore before everything got put back together. Measured the stock wheel weight indirectly by subtraction vs. the winter tire weight, and got approx 22# for the stock 17" wheel, which seems fairly heavy.
